In June 2012, TonenGeneral Sekiyu K.K. and EMG Marketing Godo Kaisha (formerly ExxonMobil Yugen Kaisha) began operations as part of a new integrated production and sales group owned primarily by Japanese shareholders.
The significance of the restructuring can be better understood by looking back at the Group's 120-year history.

Standard Oil Company of New York (Socony) opened its first Japanese branch in Yokohama in 1893 to import and sell kerosene at a time when kerosene lamps were still used for lighting. Vacuum Oil Company also opened a branch in Yokohama that same year. Vacuum Oil's high-grade lubricants and technical services were factors in bringing Japan's textile spinning industry to world prominence. The eventual sale of petroleum products under the Esso and Mobil brands also originated with Vacuum Oil.
Meanwhile, domestic oil companies established Toa Nenryo Kogyo in 1939 through joint capital investment to manufacture aviation gasoline and aviation lubricants, then regarded as high-tech products. Toa Nenryo Kogyo, an oil refining company, founded Tonen Sekiyu Kagaku in 1960 to expand its business into the petrochemical industry during the high-growth period of the Japanese economy.
Another event that contributed to our history was the establishment of General Bussan, originally the fuel department of Mitsui & Co. until it was made independent with the dissolution of the zaibatsu conglomerates in 1947. The company later became involved in petroleum refining and the sale of petroleum products under the General brand.
These three strands of our history came together with the formation of the ExxonMobil Japan Group in 2000.
However,  the ExxonMobil Japan Group had a complicated capital structure: ExxonMobil Yugen Kaisha was wholly owned by ExxonMobil, while TonenGeneral Sekiyu, listed on the First Section of the Tokyo Stock Exchange, was partially (50.02%) owned by ExxonMobil Yugen Kaisha.

The new TonenGeneral Group was created in June 2012 to respond to these circumstances by integrating refining and sales with TonenGeneral Sekiyu at its core. What had been a global organization divided vertically by function and operation was transformed into an integrated, self-sufficient organization within Japan.
This revolution also means the Group has shifted to primarily Japanese ownership after having been foreign-owned for the majority of its existence. The Group now has the most efficient management structure in its 120-year history.
Since the foundation of the ExxonMobil Japan Group, we have learned and witnessed firsthand what a global company should be.
The expertise obtained from our past experience is the essence of our organization. Into this, we have integrated  a management style suitable for the Japanese market. With a global knowledge base, the new Group is capable of responding to market needs faster than ever before.
Leveraging the world's most advanced technology and expertise, the new TonenGeneral Group strives to provide superior services grounded in actual conditions in Japan, as we continue to provide a stable supply of petroleum and petrochemical products. Thank you for your continued support.
