Over the past decade, Idemitsu has expanded into renewable energy and alternative fuels. Its investments include solar power generation facilities and joint ventures focused on hydrogen production and biodiesel. These initiatives reflect the company’s strategy to diversify its energy portfolio and reduce carbon emissions across its operations.

Idemitsu Kosan serves customers in Japan through an extensive network of retail service stations branded under its name, while its trading divisions handle crude oil sourcing and product exports to markets in Asia, North America and Europe.
