Management Policies

1. Management strategy and progress report

1) Medium-term Management Outlook

In the period of the Medium-term Strategic & Financial Plan to March 31, 2006, we achieved operating results that far exceeded the quantitative targets outlined in the plan, partly attributable to rises in the commodity markets. We also invested actively in core areas and other key growth areas. We have created a new Medium-term Management Outlook, based on a company-wide consideration of the kind of business models that we should aspire to develop over the next three-to-five years, along with the initiatives necessary to achieve such aspirations. The key elements of the approach outlined in the new plan are:

•

Building a business portfolio that meets the needs of customers and of society

•

Leveraging business engineering capabilities across Mitsui and its subsidiaries (“the Group”) and optimizing resource allocation

•

Prioritizing the development of human resources. In this respect we intend to build on our existing values of challenge and creativity and freedom and open-mindedness with additional emphasis on fairness, humility and compliance. We intend to form and foster a diverse pool of capable personnel.

(1)

Corporate vision three to five years ahead – quantitative summary; and business plan for the year ending March 2007

Looking ahead three to five years, risks in the operating environment include political, economic and environmental risks. Notwithstanding these risks, we believe that the currently favorable operating environment—with simultaneous growth in different regions of the world, and strong upstream markets for mineral resources, energy and materials—is likely to continue. Based on this assumption, we envisage achieving the parameters over the next three to five years as illustrated in the chart below.

LOGO

(2)

Four key strategies of the Medium-term Management Outlook

(a)

Development of Strategic Business Portfolio

(i)

We have developed key policies based on dividing up the Group’s business into four areas, outlined below. In working toward our vision for three to five years ahead, we intend to make investments of around ¥800 billion over the two years ending March 31, 2008, while also recycling assets of around ¥100—200 billion.

-3-

•

In the area of mineral resources and energy, we intend to complete the development of large-scale projects such as Sakhalin II and expand existing projects such as the LNG project in Western Australia and iron ore and coal production in Australia, while investing selectively in high-quality new projects.

•

In the area of global marketing networks, particularly in steel products, chemical products and machinery, we will provide SCM (supply chain management) and other sophisticated functions. We will focus on the automobile, IT and energy industries as our market, and focus on developing areas through collaboration with three regional headquarters particularly Asia.

•

In the consumer service area, we will create closer collaboration by bringing together the Lifestyle, Consumer Services, and Information, Electronics & Telecommunication business units, and focus on developing businesses that can become future earnings base.

•

In the infrastructure area, we will invest selectively in high-quality projects mainly in power generation, water supply, energy and transportation.

LOGO

(ii)

Based on the Portfolio Management Committee that we established in April 2006, we will create and re-engineer our business portfolio, and optimize the allocation of our available resources. We will refine our investment evaluation criteria, and seek to recycle existing investments.

(iii)

Accompanying a review of our business portfolio, we will allocate and shift human resources from a group-wide perspective in a more dynamic fashion.

(b)

Evolution of business models leveraging business engineering capabilities

•

We will focus on consumer-oriented services in Japan that show the greatest potential for growth, including: media and information; health, medical and senior care; retail support, and outsourcing.

•

We will pursue business development in environment-related businesses such as emission rights trading and recycling, along with new energy businesses such as biomass ethanol and solar power.

•

We will seek to leverage across the Group our strengths in logistics, finance and IT, and actively promote joint operations among business units.

(c)

Implementation of global strategies

•

We will focus the allocation of human resources on growth sectors in Asia, and strengthen our strategic partnership with our customers.

•

Based on our regional headquarters we have created for the Americas, Europe and Asia, we will develop a broad, cross-border product strategy.

•

We will employ and foster the development of a diverse group of personnel at overseas trading and other subsidiaries and associated companies around the world.

-4-

(d)

Reinforcing a management framework to support growth

•

Under our revised corporate staff organization, we are pursuing an efficient risk management approach.

•

We will continue to review and strengthen our system of corporate governance, implementing measures such as the increase in external directors and external corporate auditors in June 2006.

•

While working to ensure compliance with Section 404 of the U.S. Sarbanes-Oxley Act (“SOX 404”), which applies from the fiscal year ending March 31, 2007, we are working to enhance our internal control over financial reporting.

•

We will continue to pursue a CSR-oriented management approach that reflects the characteristics of Mitsui, seeking to develop as a business that meets the needs of customers and society while engaging in environmental issues and contributing to society, primarily through the CSR Promotion Division established in April 2006.

2)	Progress on Medium-term Management Outlook

(1)

Progress on key initiatives

(a)

Development of Strategic Business Portfolio

(i)

Investment plan

Medium-term Management Outlook intends to make investments around ¥800 billion over the two years ending March 31, 2008. In the six-month period ended September 30, 2006 we have made investments of ¥230 billion.

•

In the metal resources and energy area, based on the Medium-term Management Outlook (as shown below), we continued to make investments aimed at increasing our equity production volumes. Our total investment in the Sakhalin II project was approximately ¥350 billion as of the end of September 2006, an increase of ¥47 billion ^(*) compared to the end of March 2006.

For an update on the progress of the Sakhalin II project please also see “Key Topics”. We also acquired oil and gas interests valued at ¥53.2 billion in the offshore Gulf of Mexico, through an agreement with Pogo Producing Company. Furthermore, in March 2007, we plan to make Mitsui Oil Exploration Co., Ltd. (MOECO), currently one of our associated companies, into a subsidiary (in which we will increase the voting rights to 50.3%). In Australian iron ore and coal business, we made investments of ¥26.7 billion , as part of our plan to increase production capacity.

(*)

including effect from foreign exchange translation

•

In infrastructure projects business, we invested ¥27.5 billion for the acquisition of Gás Participações Ltda. (Brazil) (“Gaspart”) and other Brazilian gas distribution operations. We also invested ¥10.3 billion to acquire newly-issued shares of Toyo Engineering Corporation with the aim to enhancing collaboration in the infrastructure projects businesses, which are growing in size in all regions.

•

In the global trading networks area, in response to rising demand for salt for use as a raw material in the chlor-alkali industry, we acquired the Onslow salt field in Australia in June 2006. Furthermore, in September 2006, we launched an initiative in the automobile parts business, acquiring newly issued shares in automobile parts manufacturer Asahi Tec Corporation, which increased its capital to fund expansion of overseas operations, particularly in the United States.

-5-

•

In consumer products and services business, we completed a ¥5.8 billion investment in Brightstar Corp., a major U.S. distributor of mobile handsets, and aim to expand our mobile phone business in the Asia-Pacific region.

(ii)

Continuous review of our business portfolio based on Mitsui’s business strategy

Mitsui’s President sits down twice a year for face-to-face discussions with the Chief Operating Officers of each business unit to review the profitability and viability of subsidiaries and associated companies. From this fiscal year the scope of these examinations has been widened to include the entire portfolio of each Business Unit. The examinations cover business domain prioritization, recycling of inefficient assets, and improvement in the quality of monitoring of subsidiaries and associated companies.

(b)

Evolution of our new business models leveraging business engineering capabilities

In April 2006, we reached an agreement with Petróleo Brasileiro SA (“Petrobras”) of Brazil to jointly implement a feasibility study for producing bioethanol and related products in Brazil and exporting and selling them internationally. Mitsui aims to pursue with comprehensive cross-divisional efforts for the commercialization of biomass ethanol.

(c)

Implementation of global strategy

In accordance with our policy of strengthening our business strategy in the broad economic regions of Asia, Europe and the Americas, we introduced the Regional Business Unit system in April 2006. The Asia Business Unit is working in partnership with the Iron & Steel Raw Material and Non-Ferrous Business Unit of Mitsui’s Head office towards the acquisition of a 25% equity stake (equivalent to approximately ¥18 billion) in Erdos Electrical Power & Metallurgical Co., Ltd. of China’s Inner Mongolia Autonomous Region, with the aim of expanding our business in China.

(d)

Enhancing management systems to support growth

Section 404 of the U.S. Sarbanes-Oxley Act (“SOX 404”) has become applicable to Mitsui from the fiscal year ending March 31, 2007. Mitsui and its subsidiaries subject to SOX 404 have for the most part completed self-evaluation on internal controls over financial reporting, and audits by the independent auditor are steadily commencing.

With regard to the DPF incident, where Mitsui sold diesel particulate filters (“DPFs”) for diesel cars for which false data had been produced and submitted to the authorities, we completed the redemption of the DPFs in question. To ensure that we never forget the lessons learned from this incident, which caused major concern to all stakeholders including our customers and the related authorities, and seriously damaged our social trust, we continue to work vigorously to ensure that our compliance systems are thorough and robust.

(2)

Progress toward quantitative targets

(a)

Operating results for the year ending March 31, 2007

LOGO

For the six-month period ended September 30, 2006, we recorded net income of ¥159.2 billion. Please also refer to “Highlights of Consolidated Financial Results for the Six-Month Period Ended September 30, 2006” for detailed information by operating segment.

For the year ending March 31, 2007, we are revising our outlook of net income to ¥300 billion. The year-on-year comparison of annual operating results by operating segment is provided as below:

-6-

•

The net income of the Iron & Steel Raw Materials and Non-Ferrous Metals Segment for the year ending March 31, 2007 under revised plan is ¥100 billion, an increase of ¥45.3 billion compared to the year ended March 31, 2006. This is primarily attributable to higher iron ore and copper prices; in addition this segment recorded one time gains on sales of shares in Toho Titanium Co., Ltd. and stake in Aluminium smelters in the United States by Mitalco, as part of the initiative to recycle existing assets.

•

The net income of the Energy Segment for the year ending March 31, 2007 under revised plan is ¥77 billion, an increase of ¥36.1 billion compared to the year ended March 31, 2006, mainly attributable to growing revenues at oil and gas producing operations reflecting higher oil price and the commencement of commercial production at the Enfield oil field in Western Australia in July 2006(*).

(*)

Mitsui E&P Australia Pty. Ltd. (“MEPAU”) owns interest in Enfield project. Mitsui, with its fiscal year ending on March 31, consolidates operating results of MEPAU whose fiscal year ends on December 31. Therefore, there is a 3 month time lag between the operating results of MEPAU and its reflection into our consolidated operating results. Namely, MEPAU’s operating results will be reflected in our consolidated operating results from the third quarter of the year ending March 31, 2007.

•

The net income of the Iron & Steel Products Segment and the Chemical Segment for the year ending March 31, 2007 under revised plan is ¥20 billion and ¥20 billion for both segments, increases of 0.6 billion and ¥7.9 billion, respectively, compared to the year ended March 31, 2006. The firm market conditions are supporting their steady results. Furthermore, the Chemical Segment recorded ¥9 billion (¥5 billion after tax) of Compensation and Other Charges Related to DPF Incident for the year ended March 31, 2006.

•

The net income of the Machinery & Infrastructure Projects Segment for the year ending March 31, 2007 under revised plan is ¥34 billion, an increase of ¥3.4 billion compared to the year ended March 31, 2006. The firm results are supported by automobile and vessel related operations, in addition, overseas power generation businesses also contribute to the improvement, which includes the expanding operations at IPM Eagle LLP.

•

We have revised the planned net income of the Foods & Retail Segment for the year ending March 31, 2007 as zero, an improvement of ¥3.2 billion compared to the year ended March 31, 2006. This segment reported a ¥3.2 billion net loss for the year ended March 31, 2006 reflecting net loss of ¥10.9 billion at MITSUI FOODS CO., LTD. For the year ending March 31, 2007, Mitsui Norin Co., Ltd. recorded ¥9.0 billion net loss due to impairment losses on goodwill and other intangible fixed assets in the first half, which causes slow down in recovery in the segment’s operating results.

In May 2006, we announced the outlook of the consolidated net income for the year ending March 31, 2007 as ¥240 billion. However, considering the favorable operating results in mineral resources and energy related businesses as mentioned above, we have revised it to ¥300 billion. The comparison table set forth below shows the assumption of the commodity prices and other parameters for the year ending March 31, 2007 with the impact of the commodity price movements on net income. As of end of the first half period, we observe positive price trends in mineral resources and crude oil compared to the beginning of this fiscal year.

Financial conditions as of September 30, 2006

Total assets as of September 30, 2006 was ¥9.4 trillion, an increase of ¥0.8 trillion from ¥8.6 trillion as of March 2006. The net debt-to-equity ratio (“DER”) was 1.69 times, the same level as March 31, 2006. The annualized ROE for the first half period was 18.1%, higher than 14.5% for the year ended March 31, 2006.

Net cash provided by operating activities for the six-month period ended September 30, 2006 was ¥36.0 billion, reflecting the steady growth of the operating income, while net cash used in investing activities was ¥232.0 billion, attributable to investments mainly in the energy and mineral resources businesses. As a result, free cash flow for the six-month period ended September 30, 2006 was net outflow of ¥196.0 billion. For the full year ending March 31, 2007, we expect that overall the similar trend of negative free cash flow will continue.

For further information, please see “Highlights of Consolidated Financial Results for the Six-Month period Ended September 30, 2006.”

2. Key topics

Sakhalin II project

The Sakhalin II Phase 2 Project continues to progress in accordance with the Production Sharing Agreement, and the construction work is now more than 80% complete towards the scheduled start of LNG delivery in summer 2008. In the meantime, Sakhalin Energy Investment Company Ltd. (“SEIC”) is closely working with the relevant authorities to resolve the environmental issues raised by the Ministry of Natural Resources of the Russian Federation.

3. Dividend policy

In order to maximize shareholder value we seek to maintain an optimal balance between (1) achieving sustainable growth through strategic investments in areas of our core strength and growth and (2) paying out cash dividends as direct compensation to shareholders. Specifically, we have set the target dividend payout ratio of 20% of consolidated net income, and through improving the performance of the company, we aim to steadily increase dividends from their current levels.

For the six-month period ended September 30, 2006, we decided to pay an interim dividend of ¥17 per share, ¥7 per share higher than the previous corresponding period. For the year ending March 31, 2007, we will closely review improvements in business performance with the aim of increasing dividends for the full year above current levels, based on the policy outlined above.

4. Share trading unit

Our capital market policy reflects the importance of securing long-term, stable shareholders and expanding our investor base. We carefully review the appropriateness of our minimum share trading unit and investor distribution on an annual basis.

Highlights of Consolidated Financial Results for the Six-Month Period

Ended September 30, 2006

1. Operating Results for the Six-Month Period Ended September 30, 2006

(1) Operating Environment

Against a backdrop of steady performance by the U.S. economy, broad-based expansion continued with China and other emerging economies continuing to post high growth, Europe shifting to a recovery trend and the Japanese economy performing well. In the United States, corporate profits remained robust and consumer spending continued to increase, and despite an easing in housing investment, which had been overheating, the economy performed steadily overall. China and other emerging economies continued to achieve high growth, driven by further expansions in capital investment and increases in exports.

This broad-based expansion of the global economy underpinned strong international commodities markets. Prices of crude oil, non-ferrous metals and other commodities reached record-high levels in the summer, and despite falling thereafter, remain at high levels. The global trend towards steadily higher interest rates continued, and in the United States, the raising of policy interest rates that began in 2004 continued during the first half of this fiscal year, while Europe and Japan also raised interest rates.

The Japanese economy continued its robust recovery. Exports continued to increase, bolstered by the global economic expansion and the weakening yen. Strong corporate sector results led to increased capital investment particularly in the digital home appliance field, while improvements in employment and wages led to firmer consumer spending.

(2) Summary of Operations for the Six-Month Period Ended September 30, 2006

An overview of the results of the operations for the six-month period ended September 30, 2006 is set forth below:

•

For the six-month period ended September 30, 2006, Mitsui & Co., Ltd. and its subsidiaries (“the Group”) recorded net income of ¥159.2 billion, an increase of ¥76.0 billion, or 91.3 %, compared to ¥83.2 billion for the corresponding six-month period of the previous year, mainly attributable to the increase in gross profit and equity in earnings of associated companies. Overall operating segments except for the Foods & Retail Segment and the Lifestyle, Consumer Service and Information, Electronics & Telecommunication Segment recorded improved operating results primarily in mineral resources and energy related businesses, which benefited from a favorable economic environment.

•

The combined sum of net income and net loss from subsidiaries and associated companies for the six-month period ended September 30, 2006 was ¥135.0 billion, an improvement of ¥42.4 billion compared to ¥92.6 billion for the corresponding six-month period of the previous year. The combined sum of net loss from unprofitable subsidiaries and associated companies was ¥25.1 billion, primarily attributable to impairment losses on goodwill and intangible assets at Mitsui Norin Co., Ltd. and increased interest expenses for investment in the Sakhalin II project.

Current assets as of September 30, 2006 were ¥5,156.5 billion, an increase of ¥409.7 billion compared to ¥4,746.8 billion as of March 31, 2006, mainly attributable to:

•

a ¥141.1 billion increase in marketable securities such as commercial paper at Mitsui; and

•

increases in trade receivables, inventories and derivative assets primarily at the Energy Segment, the Iron & Steel Raw Materials and Non-Ferrous Metals Segment and the Chemical Segment, reflecting higher market prices and increased business transactions.

Total current liabilities as of September 30, 2006 were ¥4,085.5 billion, an increase of ¥574.6 billion compared to ¥3,510.9 billion as of March 31, 2006, primarily because of increases in:

•

short-term debt by ¥232.0 billion at Mitsui and overseas financial subsidiaries; and

•

trade payables and derivative liabilities corresponding to increases in the above-mentioned current assets.

As a result, working capital, or current assets minus current liabilities, as of September 30, 2006 was ¥1,071.0 billion, a decrease of ¥164.9 billion compared to ¥1,235.9 billion as of March 31, 2006.

The sum of total investments and non-current receivables, property and equipment—at cost, intangible assets less accumulated amortization, deferred tax assets—non current and other assets as of September 30, 2006 totaled ¥4,225.6 billion, a ¥398.9 billion increase compared to ¥3,826.7 billion as of March 31, 2006, mainly due to the following factors:

•

Within total investments and non-current receivables, investments in and advances to associated companies as of September 30, 2006 was ¥1,471.6 billion, a ¥171.0 billion increase compared to ¥1,300.6 billion as of March 31, 2006. Major components were:

the Sakhalin II project for ¥47.0 billion (including effect from foreign exchange translation of ¥2.1 billion);

the acquisition of Gaspart and other gas distribution operations in Brazil for ¥30.3 billion; and

acquisition of newly-issued shares of Toyo Engineering Corporation for ¥10.3 billion.

In addition to the above-mentioned increases, there were increases which do not involve cash outflow such as:

increases in equity in earnings (before tax effect) of ¥53.9 billion (net of ¥54.3 billion dividends received from associated companies);

a ¥10.7 billion net improvement in foreign exchange translation cumulative adjustments; and

a net decrease of ¥4.1 billion in unrealized holding gains and losses on available-for-sale securities held by associated companies.

Other investments were ¥964.8 billion, a ¥29.1 billion increase compared to ¥935.7 billion as of March 31, 2006. This was due to purchases of shares in Nippon Steel Corporation for ¥10.0 billion and Brightstar Corp of the United States for ¥5.8 billion; and investment in partnership which owns Skylark Co., Ltd., restaurant chains in Japan, for ¥ 10.0 billion.

•

Property and equipment—at cost as of September 30, 2006 was ¥873.5 billion, an increase of ¥127.3 billion compared to ¥746.2 billion as of March 31, 2006. Major components were:

the newly acquired oil and gas project in the offshore Gulf of Mexico for ¥58.2 billion (including effect from foreign exchange translation of ¥1.9 billion);

the oil and gas projects of Enfield and Vincent oil filed in Australia, Tui oil field in New Zealand and oil and gas project in Oman in total for ¥32.7 billion (including effect from foreign exchange translation of ¥1.8 billion);

the iron ore and coal mining projects in Australia for ¥29.8 billion (including effect from foreign exchange translation of ¥6.3 billion); and

the Onslow salt field in Australia for ¥10.4 billion.

Long-term debt, less current maturities as of September 30, 2006 was ¥2,699.3 billion, an increase of ¥40.6 billion compared to ¥2,658.7 billion as of March 31, 2006 mainly due to a ¥13.9 billion increase in borrowings from financial institutions associated with funding for the acquisition of leased assets at rolling stock leasing subsidiaries.

Shareholders’ equity as of September 30, 2006 was ¥1,834.2 billion, an increase of ¥156.3 billion compared to ¥1,677.9 billion as of March 31, 2006, primarily due to the increase in retained earnings by ¥135.0 billion and net improvement in foreign currency translation adjustments by ¥26.8 billion as a result of stronger U.S. dollar and Australian dollar against Japanese Yen.

-23-

As a result of the above, shareholders’ equity to total assets ratio as of September 30, 2006 was 19.5%, a 0.1 percentage point decline compared to 19.6 % as of March 31, 2006. Net interest bearing debt, or interest bearing debt minus cash and cash equivalents and time deposits as of September 30, 2006 was ¥3,102.3 billion, an increase of ¥271.7 billion compared to ¥2,830.6 billion as of March 31, 2006. Net debt-to-equity ratio as of September 30, 2006 was 1.69 times, the same level as March 31, 2006.

Net Debt-to-Equity Ratio

The Group refer to “Net Debt-to-Equity Ratio” (“Net DER”) in this flash report. Net DER is comprised of “net interest bearing debt” divided by shareholders’ equity.

“Net interest bearing debt” is defined as adjusted interest bearing debt described as below less cash and cash equivalents and time deposits. The Group’s interest bearing debt primarily consists of long term debt, less current maturities, which are not readily repayable. In order to flexibly meet capital requirements and to prepare for future debt-service requirements in case of unforeseen deteriorations in financial markets, currently the Group holds a relatively high level of cash and cash equivalents reflecting the current financial market conditions and future capital requirements.

Under this policy, Net DER is a useful internal measure for the Group’s management to review the balance between:

•

the Group’s capacity to meet debt repayments; and

•

leverage to improve return on equity in the Group’s capital structure.

To calculate the Group’s adjusted interest bearing debt, the following are the eliminating factors:

•

accounts payables, derivative liabilities and others;

•

capital lease obligations; and

•

SFAS No. 133 fair value adjustment.

The Group eliminates of SFAS No. 133 fair value adjustment because Japanese investors usually evaluate Net DER of other general trading companies in this manner.

This measure does not recognize the fact that cash and cash equivalents and time deposits may not be available completely for debt repayments, but cash and cash equivalents and time deposits may be required for operational needs including certain contractual obligations or capital expenditure.

“Net interest bearing debt” and “Net DER” are presented in the table below.


	Billions of Yen
	End of Sep. 2006			End of Mar. 2006
Short-term debt	¥	772.8		¥	540.8

(2) Cash Flows

•

Net cash provided by operating activities for the six-month period ended September 30, 2006 was ¥36.0 billion, a slight increase of ¥2.0 billion compared to ¥34.0 billion for the corresponding period of the previous year. While operating income grew steadily, the Group recorded significant increase in trade receivables and inventories for the six-month period ended September 30, 2006.

•

Net cash used in investing activities for the six-month period ended September 30, 2006 was ¥232.0 billion, a ¥47.4 billion increase compared to ¥184.6 billion for the corresponding six-month period of the previous year. The outflow of cash that corresponded to the above-mentioned acquisition of assets included investments in:

the newly acquired oil and gas project in the offshore Gulf of Mexico for ¥53.2 billion(*);

the Sakhalin II project for ¥44.9 billion (*);

Gaspart and other gas distribution operations in Brazil for ¥27.5 billion (*);

iron ore and coal mining projects in Australia for ¥26.7 billion (*);

the oil and gas projects of Enfield and Vincent oil filed in Australia, Tui oil field in New Zealand and oil and gas project in Oman in total for ¥21.9 billion (*);

Onslow salt field in Australia for ¥7.0 billion (*);

acquisition of newly-issued shares of Toyo Engineering Corporation for ¥10.3 billion; and

purchase of shares in Nippon Steel Corporation for ¥10.0 billion and investment in partnership which owns Skylark Co., Ltd., restaurant chains in Japan, for ¥ 10.0 billion.

On the other hand, Mitsui obtained ¥16.5 billion through the sale of shares in Toho Titanium Co., Ltd.

As a result, free cash flow, or sum of net cash provided by operating activities and net cash provided by investing activities, for the six-month period ended September 30, 2006 was net outflow of ¥196.0 billion, a ¥45.4 billion increase in net outflow compared to ¥150.6 billion outflow for the corresponding six-month period of the previous year.

•

During the six-month period ended September 30, 2006, net cash inflow by short-term debt was ¥210.1 billion, which was mainly raised by Mitsui and overseas subsidiaries. Net cash inflow raised by long-term debt was insignificant. Thus, net cash provided by financing activities was ¥202.7 billion after the payments of cash dividends by ¥24.1 billion and for the acquisition of treasury stock.

As a result, cash and cash equivalents as of September 30, 2006 were ¥706.5 billion, a ¥9.4 billion increase compared to ¥697.1 billion as of March 31, 2006.

(*)	Cash flows in foreign currencies were translated into yen using the average foreign exchange rates during the year, and therefore differ from the amounts appearing in “Assets, Liabilities and Shareholders’ Equity” as above, which were translated by the current rate as of September 30, 2006.

4. Risk Factors

You should note that the risk factors set forth below do not represent all the Group’s risk factors, and changes in economic and other conditions could lead to outcomes that differ from those presented below.

(1) Risk factors derived from changes in market environments

The following are typical risk factors derived from changes in market environments.

The decrease in the volume of trade and the flow of goods and materials resulting from the worldwide economic downturn may adversely impact the Group’s business, results of operations and financial condition.

The Group’s global business activities, including our trading activities are affected by the particular economic conditions of the countries in which the Group operates. The Group is particularly vulnerable to the downward economic trends in Japan. In addition, an economic downturn in China, which has become an increasingly important market for us due to increasing trading and business transactions involving raw steel materials, steel products, chemical products and infrastructure projects, may also adversely affect the Group’s results of operations. An economic downturn, either globally or in any regions in which the Group operate may cause, among other things, a reduction in flow of goods and materials, a decline in private consumption and fixed investment, and subsequently a decrease in demand of the Group’s customers for the Group’s products and services, which may have an adverse impact on the Group’s business, results of operations and financial condition.

Fluctuations in commodity prices can adversely affect the Group’s results of operations and financial condition.

The Group trades in a variety of commodities in the global commodities market including metal, energy, chemical and agricultural products. The Group’s trading activities in these commodities in particular, have a significant impact on the Group’s business operations. As a result, unexpected movements in commodity prices may adversely affect the Group’s business, operating results and financial condition. For instance, the operating results of the Group’s oil and gas are sensitive to the price of crude oil. A decline of U.S.$1 per barrel in the price of crude oil results in a decrease in the Group’s net income of approximately ¥1.6 billion as of the year ending March 31, 2007. And with respect to the Group’s iron ore and coal production, a decline of U.S.$1 per 1 ton in the each price of iron ore and coal results in a decrease in the Group’s net income approximately ¥2.7 billion and ¥0.5 billion respectively for the year ending March 31, 2007. These estimations are based on the assumption of the Group’s annual production from above-mentioned activities calculated and foreign exchange rates during the year ending March 31, 2007, thus the sensitivities to these commodity prices for the year ending March 31, 2007 will vary.

-26-

Exchange rate fluctuations may adversely affect the Group’s operating results.

The Group is exposed to risks associated with foreign currency exchange rate fluctuations. Although the Group’s reporting currency is the Japanese yen, a significant portion of the Group’s business operations, consolidated revenues and operating expenses is denominated in currencies other than the Japanese yen. As a result, appreciation or depreciation in the value of other currencies as compared to the Japanese yen could result in material transactional gains or losses. As the financial statements of overseas subsidiaries are stated in the U.S. dollar, the Australian dollar, the Euro, or other currencies, the Group’s net income may be affected by the fluctuations of these currencies and the Group is exposed to translation risk in the Group’s assets and liabilities denominated in foreign currencies. As a result, exchange rate fluctuations may negatively affect the Group’s operating results.

Changes in interest rates could have an adverse effect on the Group’s operating results.

The Group is exposed to risks associated with interest rate fluctuations, which may affect the Group’s overall operational costs and the value of its financial assets and liabilities, particularly, its debt obligations, which are primarily debt raised in the capital markets and bank loans. The Group utilizes various financial and derivative instruments which are sensitive to interest rate changes. An increase in interest rates, especially in Japan and the United States, may adversely affect the Group’s results of operations.

(2) Risks factors derived from failure to achieve compliance with laws, regulations and rules

Besides the risk factors related to strategic and management decision such as entry to or withdrawal from new market and control of subsidiaries and associated companies, risk factors derived from failure to achieve compliance with laws, regulations and rules could lead to outcome that affect the Group’s operating results and business negatively.

Restrictions under environmental laws and regulations and any accidents relating to the Group’s use of hazardous materials could negatively affect the Group’s business, results of operations and financial condition.

As a global general trading company, the Group is involved in various projects and business transactions worldwide that are subject to extensive environmental laws and regulations. In particular, the Group’s Metal Products & Minerals Segment and Energy Segment may be adversely affected by present or future environmental regulations or enforcements in connection with the Group’s extracting activities. For example, the Group is subject to complex sets of environmental regulations in Australia, Brazil, Russia, and the Middle East. These laws and regulations may require us to perform site clean-ups; require us to curtail or cease certain operations; impose fines and payments for significant environmental damage; require us to install costly pollution control equipment; and require us to modify the Group’s operations.

The Group is a shareholder of Coronet Industries Inc. (“Coronet”), a former manufacturer of animal feed supplements. Coronet has been working with the U.S. Environmental Protection Agency (“EPA”) and the State of Florida on an investigation of environmental conditions and former operations at its facility in Florida. In addition, Coronet has been named as a defendant in two civil actions initiated by residents living near the plant. Mitsui, as well as its United States subsidiary, Mitsui & Co. (U.S.A.), Inc., have been named as defendants in one of these actions. These actions are both at their early stages.

-27-

Employee misconduct could adversely affect the Group’s results of operations and reputation.

Due to the Group’s size, as well as the operational and geographic breadth of the Group’s activities, the Group’s day-to-day operations are necessarily de-centralized. As a result, the Group cannot fully ensure that the Group’s employees comply with all applicable laws and regulations as well as the Group’s internal policies. For example, the Group’s employees may engage in unauthorized trading activities and exceed the allotted market risk exposure for various commodities or extend an unauthorized amount of credit to a client, which, in either case, may result in unknown losses or unmanageable risks. Moreover, the Group’s employees could engage in various unauthorized activities prohibited under the laws of Japan or other jurisdictions, to which the Group is subject, including export regulations, anticorruption laws, antitrust laws and tax regulations. There can be no assurance that the efforts the Group undertakes to ensure employees’ compliance with applicable laws and regulations as well as the Group’s internal policies will succeed in preventing misconduct by the Group’s employees. Depending on its nature, employees’ misconduct could have negative effects on the Group’s results of operations and reputation.

5. Outlook for the Year Ending March 31, 2007

With regard to the outlook for the year ending March 31, 2007, the Group anticipates:

•

total trading transactions of ¥15,000 billion, increasing ¥114 billion, or 0.8%, compared with ¥14,886 billion for the year ended March 31, 2006; and

•

net income of ¥300.0 billion, increasing ¥97.6 billion, or 48.2%, compared with ¥202.4 billion for the year ended March 31, 2006.

These forecasts assume the revised parameters as below:

•

average currency exchange rate of ¥112.66 = U.S. $1.00 (the first half ¥115.33 and the second half ¥110.00); and

•

average crude oil price(*) of U.S.$64 per barrel (the first half U.S.$63 and the second half U.S.$65)

(*)	This crude oil price (JCC: Japan Crude Cocktail) is applied to the sales prices at the Group’s oil and gas producing subsidiaries and associated companies, and the effect of change in JCC price is reflected to their operating results with 0 to 6 months time lag.

For the impact of the price fluctuation of crude oil, iron ore and coal on the Group’s net income, please see “4. Risk Factors - 1) Risk factors derived from changes in market environments”.

Basis of Financial Statements and Summary of

Significant Accounting Policies

(Unaudited)

I. Basis of Financial Statements

The accompanying consolidated financial statements of Mitsui & Co., Ltd. (the “Company”) and its subsidiaries (collectively, the “companies”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

II. Summary of Significant Accounting Policies

(1) Inventories

Inventories, consisting mainly of commodities and materials for resale, are stated at the lower of cost, principally on the specific-identification basis, or market.

(2) Debt and marketable equity securities

The companies classify debt and marketable equity securities, at acquisition, into one of three categories: held-to-maturity, available-for-sale or trading under provisions of Statement of Financial Accounting Standards (“SFAS”) No. 115, “Accounting for Certain Investments in Debt and Equity Securities.”

Trading securities are carried at fair value and unrealized holding gains and losses are included in earnings.

Debt securities are classified as held-to-maturity and measured at amortized cost in the Consolidated Balance Sheets only if the companies have the positive intent and ability to hold those securities to maturity. Premiums and discounts amortized in the period are included in interest income.

Debt and marketable equity securities other than those classified as trading or held-to-maturity securities are classified as available-for-sale securities and carried at fair value with such unrealized holding gains and losses reported as “Unrealized holding gains and losses on available-for-sale securities” in Shareholders’ Equity after income tax effects.

(3) Depreciation

Depreciation of property and equipment (including property leased to others) is computed principally under the declining-balance method for assets located in Japan and under the straight-line method for assets located outside Japan, using rates based upon the estimated useful lives of the related property and equipment. Mineral rights are amortized over their respective estimated useful lives, using the straight-line method or the unit-of-production method.

Leasehold improvements are amortized over the lessor of the useful life of the improvement or the term of the underlying lease.

(4) Pension and severance indemnities plans

The companies have pension plans and/or severance indemnities plans covering substantially all employees other than directors. The costs of the pension plans and severance indemnities plans are accrued based on amounts determined using actuarial methods in accordance with SFAS No. 87, “Employers’ Accounting for Pensions.”

(5) Derivative instruments and hedging activities

All derivative instruments are recognized and measured at fair value as either assets or liabilities and changes in the fair value are currently recognized in earnings or reported as “Net unrealized gains and losses on derivatives” in Shareholders’ Equity after income tax effects, depending on the intended use of the derivative instruments and its resulting hedge designation.

(6) Business combinations and intangible assets

Under provisions of SFAS No. 141, “Business Combinations” and SFAS No. 142, “Goodwill and Other Intangible Assets,” all business combinations are accounted for using the purchase method, and goodwill acquired upon business combinations and indefinite-lived intangible assets are tested for impairment annually or more frequently if impairment indicators arise.

-39-

(7) Discontinued operations

The companies present the results of discontinued operations (including operations of a subsidiary that either has been disposed of or is classified as held for sale) as a separate line item in the Statements of Consolidated Income under “Income from Discontinued Operations—Net (After Income Tax Effect)” in accordance with SFAS No. 144. The amounts in the Statements of Consolidated Income and the Statements of Consolidated Cash Flows for the previous periods have been reclassified.

(8) Asset retirement obligations

Under provisions of SFAS No. 143, “Accounting for Asset Retirement Obligations,” the companies record a liability for an asset retirement obligation at fair value in the period in which it is incurred. When the liability is initially recorded, the companies capitalize the related cost by increasing the carrying amount of the long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset.

(9) Revenue presentation

The revenues are presented in accordance with Financial Accounting Standards Board (“FASB”) Emerging Issues Task Force Issue (“EITF”) No. 99-19 and are classified by major class as required by the U.S. Securities and Exchange commission (“SEC”) Regulation S-X, Rule 5-03.

(10) Consolidation of variable interest entities

The variable interest entities where the Company or one of its subsidiaries is a primary beneficiary are consolidated in accordance with FASB Interpretation No. 46, “Consolidation of Variable Interest Entities (revised in December 2003)—an Interpretation of ARB No. 51.”

(11) Reclassification

Certain reclassifications have been made to prior year amounts to conform to the current year presentation.

Notes:		1.		In accordance with SFAS No.144, the figures of “Consolidated Total” for the six-month period ended September 30, 2005 have been reclassified.

“All Other” includes business activities which primarily provide services, such as financing service and operation services to external customers and/or to the companies and associated companies. Total assets of “All Other” at September 30, 2006 and 2005 consisted primarily of cash and cash equivalents and time deposits related to financing activities, and assets of certain subsidiaries related to the above services.

Net loss of “Adjustments and Eliminations” includes income and expense items that are not allocated to specific reportable operating segments, such as certain expenses of the corporate departments, and eliminations of intersegment transactions.

Transfers between operating segments are made at cost plus a markup.

Operating Income (Loss) reflects the companies’ a) Gross Profit, b) Selling, general and administrative expenses, and c) Provision for doubtful receivables.

Starting from the year ended March 31, 2006, Iron & Steel Products and Iron & Steel Raw Materials and Non-Ferrous Metals which formally composed the “Metal Products & Minerals,” and Foods & Retail, which was formally included in “Consumer Products & Services” are disclosed as a separate product- focused reportable operating segment, and Electronics & Infomation, which was formally included in the “Machinery, Electronics & Information” is aggregated to Life Style and Consumer Service, which were formally included in “Consumer Products & Services” and disclosed as “Life Style, Consumer Service, Information, Electronics and Telecommunication.” Machinery and Infrastracture Projects, which were formally included in “Machinery, Electronics & Information,” are disclosed as “Machinery & Infrastracture Projects.”

Also, starting from the six-month period ended September 30, 2006, Mitsui & Co., Financial Services (Europe) which was formerly included in “Europe,” is transferred to “All Other,” in order to centralize the operation of financing services to the companies and associated companies.
