The company traces its roots back to the early 1970s during which time ITC acquired various petroleum interests in Indonesia. The acquisition of interests in the offshore Southeast Sumatra and Northwest Java by ITC in 1970 led to the establishment of Japan Low Sulfur Oil Co., Ltd. (JALOSCO). In 1972, ITC formed C. Itoh Energy Development Co., Ltd. (CIECO) to invest and acquire assets in the Vogelkop and Irian Jaya oil fields. In 1984, JALOSCO merged with CIECO, setting the stage for the subsequent evolution into the current corporate structure. The successful production of oil and natural gas in the Indonesian fields during the 1980s and thereafter prompted CIECO to expand its operations into other areas around the world.

CIECO, headquartered in Tokyo, changed its corporate name to ITOCHU Oil Exploration Co.
