What コスモ石油株式会社 does
Cosmo Energy Holdings Co., Ltd. (コスモエネルギーホールディングス株式会社) is a Japanese integrated energy holding company whose core subsidiary Cosmo Oil Company (コスモ石油株式会社) operates petroleum refining (including the Sakai refinery) and a nationwide service station (gas station) network selling gasoline, diesel, kerosene, and heavy oil to individual drivers and commercial fleet operators. The group has diversified its revenue base beyond traditional petroleum by adding wind power generation (via Cosmo Eco Power), Sustainable Aviation Fuel (SAF) initiatives, a retail electricity brand (Cosmo Denki) sold through a digital sign-up flow, and a Corporate PPA program targeting enterprises seeking renewable energy procurement for carbon neutrality.
Consumer-facing operations have been expanded into an integrated mobility and energy ecosystem that includes car leasing (Cosmo My Car Lease), car sharing (Yasashii Carshare), vehicle inspection (Komitto Shaken), a proprietary official app, and co-branded card programs (Cosmo Card, Cosmo Card Opus with Aeon). Revenue is generated through transaction fees on fuel and card interchange, recurring electricity subscriptions, long-term renewable energy PPAs, and recurring or one-time mobility service fees. The group operates exclusively in Japan (domestic geographic scope) and supports its activities through sustainability programs such as the COSMO Eco Fund, J-Credit–registered forest conservation in Chiba Prefecture, and the integrated annual report (Cosmo Report 2025). Recent technology initiatives include a quadruped-robot Proof of Concept at the Sakai Refinery for autonomous equipment inspection and a joint demonstration with NSK on wind turbine bearing lubrication monitoring.
