ExxonMobil and its predecessor companies have done business in Japan for over a century. Affiliates of Standard Oil of New York (SOCONY) and Vacuum Oil set up branch offices in Yokohama in 1893, selling kerosene and lubricants.

Throughout its history, ExxonMobil has evolved to meet the dynamic needs of the energy sector and the restructuring of Japan in June 2012 was a continuation of that process. ExxonMobil Japan (EMJ) is operating as a 100% ExxonMobil affiliate. EMJ remains committed to customers, suppliers, venders and society in Japan and in the Asia Pacific region by maintaining a strong market presence and supplying a number of products and services.
