Based on its corporate principle "From producers to consumers", the IDEMITSU Group has endeavored to accomplish a crucial mission of supplying petroleum to every corner of society since its establishment in 1911.

Exploitation of oilfields, construction of large tankers, operation of refineries and petrochemical plants: these are some of the efforts that the IDEMITSU Group has continuously devoted to achieve stable supply of petroleum with its all-embracing system including drilling, transportation, refining, processing and selling of petroleum.
