The story

The company was established 1888 as the "Nippon Oil" (日本石油, Nihon Sekiyu), or "Nisseki" (日石) for short. In 1999, the company merged with and absorbed the former "Mitsubishi Oil" (三菱石油, Mitsubishi Sekiyu). The merged company was called "Nippon Mitsubishi Oil" (日石三菱, Nisseki Mitsubishi) until 2002, when it was renamed back to Nippon Oil Corporation. In 2010, NOC merged with Nippon Mining to form JX Holdings, and Nippon Oil was renamed JX Nippon Oil & Energy. In 2017, JX and TonenGeneral were merged into JXTG Holdings. The company's name was slightly modified to JXTG Nippon Oil & Energy. In June 2020, ENEOS Corporation was adopted as the current name.
