The stable supply of energy sources plays a vital role in supporting the

foundations of industrial activity and community living. The Mitsubishi

Materials Group has its roots in the coal business ----more specifically, the

operation of coal mines ---- which began in 1871. Coal was an important

commodity in those days, fueling the modernization of Japan.

Mitsubishi Materials is a clean energy company, providing nuclear,

geothermal, hydroelectric power and solar in addition to electric power

from such traditional sources as coal and petroleum, to help create

comfortable living and working environments. We also draw on a

profusion of technologies and extensive experience, accumulated through

many years in diverse energy-related pursuits, as well as our human

talents, to utilize energy wisely in the formation of sustainable community

development.

1. Nuclear Fuel Cycle BusinessMitsubishi Materials' Energy Project & Technology Center is responsible for thefollowing technology field; such as- original conversion technology development that supports uranium enrichment- manufacture of fuel assemblies and containers for the transportation of uranium

hexafluoride- process design and construction of purification & denitration of uranium and plutonium

facility which is the core process in reprocessing operations, and product storagefacilities at Rokkasho Reprocessing Plant.

In addition, the center pursures a wide range of nuclear fuel cycle-related activities,including R&D on processing and disposal of radioactive waste.

2. Geothermal Power (Onuma Geothermal Power Plant)Drawing on a wealth of underground resource development technologies accumulatedthrough coal and mineral mining, Mitsubishi Materials' Geothermal & Electric PowerDepartment began producing clean energy geothermal power in Onuma, AkitaPrefecture, in 1974. The center has been supplying steam to the Sumikawa GeothermalPower Plant since 1995. We are currently conducting feasibility studies for thedevelopment of additional geothermal power plants.

3. Coal (overseas coal mines, coal-fired power plants)Mitsubishi Materials sells thermal coal to electric power utilities in Japan and otherdomestic companies for general industrial applications. We rely primary on coal frommines in Australia and Indonesia. We also hold 11% equity in an Australian coal miningbusiness, and this investment ensures stable access to coal sources. Our strong point isthat the coal that we import have low environmental impact----that is, low sulfur and ashcontent----and have been favorably received by our clients.

[ CORPORATE HISTORY ]

MitsubishiBy the early 1940s, the original Mitsubishi zaibatsu (Mitsubishi Company), founded in the early 1870s,had expanded into virtually every sector of the economy, including mining, heavy industry, oil refining,chemicals, banking, real estate, insurance, even aircraft manufacture. It was the biggest most powerfulindustrial combine in pre-war Japan.Then, with the advent of World War II, everything changed. After the war, the single organization wasdissolved into scores of independent companies that were no longer subject to central control.The common misconception abroad however, is that Mitsubishi is still one giant company. This is not so.It is a collection of dozens of autonomous companies. Some of them have been around for more than acentury, while others have grown up in the last few years.

Mitsubishi Materials CorporationMitsubishi Materials Corporation was created on December 1, 1990 by merger of Mitsubishi MetalCorporation and Mitsubishi Mining & Cement Co., Ltd., which had been established after the WorldWar by the allied breakup of the old Mitsubishi Mining Company. Mitsubishi Materials Corporationis one of the world largest materials companies, employing more than 23,000 people in 25 countries. TheCompany has built strong positions in metal smelting and refining, cement manufacturing & metalfabricating and is now regarded as a technical leader in areas such as silicon wafer, electroniccomponents and advanced materials.
