JGC Corporation (formerly Japan Gasoline Co., Ltd.) was founded on 25 October 1928 with a capital of 10 million yen, its offices being located at Uchisaiwai-cho, Koji-machi, in Tokyo. The purpose of the establishment was to purchase cracking processing technology from UOP (Universal Oil Products) of the U.S.A. with the intent to construct and operate an oil refinery on the Pacific Rim. However, the Company opted to withdraw from refinery operations for several reasons, and instead, focused its business operations on promoting the UOP processing license. To further this new direction, the Company commenced engineering operations during the 1930's. Since the company's establishment, JGC engineering has left its mark on numerous projects in the field of hydrocarbons the world over. Many have been major, state-sponsored projects carried out in Asia, Africa, South America, Eastern Europe and the Middle East. In short, as a leading global engineering company, JGC has the accumulated experience gained from over 20,000 projects performed in approximately 70 countries.
