The company began in the early 1970s with the acquisition of petroleum interests in Indonesia (offshore SW Sumatra and NW Java), leading to the establishment of Japan Low Sulfur Oil Company Ltd (JALOSCO). IN 1972, Itoh Energy Development Co., Ltd. (CIECO) was formed and in 1984 JALESCO merged with CIECO, leading to the current corporate structure. While operating in Indonesia during the 1980, the company then expanded its operations into other regions. In 1993 CIECO changed its corporate name to ITOCHU Oil Exploration Co. Ltd.[4]
