Business
Idemitsu Kosan Co.,Ltd. is a leading Japanese petroleum company primarily engaged in the manufacture and sale of petroleum products, petrochemical raw materials, and functional materials. Its core product portfolio includes gasoline, kerosene, diesel fuel, jet fuel, lubricants, plastic resins, and various industrial chemicals derived from crude oil refining processes. The company also operates in the renewable energy sector, focusing on carbon-neutral solutions including biofuels, clean hydrogen production, and electric parts cooling oils. Additionally, it provides energy infrastructure and materials for the petrochemical industry. Idemitsu serves diverse markets across Japan, Southeast Asia, and Europe, with a comprehensive energy supply chain extending to transportation and retail fuel networks. Founded in 1911 and headquartered in Tokyo, Japan, Idemitsu Kosan continues to evolve its business with strategic expansions and innovations aimed at carbon neutrality and sustainability. In recent developments, the company has partnered with Norsepower to equip two very large crude carriers (VLCCs) with wind rotor sails, marking a key step in reducing emissions in maritime logistics. It is also undertaking a joint feasibility study with Hatch Blue for a blue carbon business and advancing clean hydrogen production from waste. In 2024, Idemitsu acquired an 8.75% stake in Fuji Oil, strengthening its strategic partnership to enhance operational efficiencies and market presence. The company plans to consolidate its ethylene production operations with Mitsui Chemicals by fiscal 2027 to optimize production and shift toward sustainable chemical manufacturing. Digital transformation investments, including ERP strategic partnerships, underpin ongoing operational reforms to improve capital efficiency and foster innovation. Idemitsu maintains a resolute focus on achieving carbon neutrality by 2050 through diversified energy and resource conservation solutions. Idemitsu Kosan operates through key business segments including Petroleum, Basic Chemicals, Functional Materials, Power and Renewable Energy, and Resources. Its renewable initiatives are supported by significant R&D investments and operational shifts such as phasing out hydrocarbon refining at certain plants to pivot towards carbon-free energy hubs leveraging solar and hydrogen technologies. The company’s international expansion and sustainable practices position it as a major integrated energy and chemical company advancing both traditional fuel supplies and low-carbon energy solutions worldwide.
