The group's history began in April 1927, when a joint-stock company (gōshi kaisha) named Denko Mumaitan Shokai was founded for the purpose of selling Korean Pyongyang anthracite. In September 1929 the company was reorganized as Tokyo Mumaitan Co., Ltd. and entered the manufacture and sale of briquettes. In April 1934 Shinagawa Mametan Co., Ltd. was established, entering the manufacture and sale of mametan (small briquettes). In May 1936 the company changed its trade name from Shinagawa Mametan Co., Ltd. to Shinagawa Fuel Co., Ltd., and in March 1937 Shinagawa Fuel Co., Ltd. and Tokyo Mumaitan Co., Ltd. merged. In September 1952 the company began selling petroleum products and related appliances (kerosene, gasoline, heavy oil, light oil, etc., and petroleum appliances). In April 1955 it began selling LP gas and related appliances (propane gas, butane gas, auto gas, gas appliances). In January 1963 it listed its shares on the Second Section of the Tokyo Stock Exchange, and in September 1983 it was designated as a First Section issue of the Tokyo Stock Exchange. In April 1998 the company changed its trade name from Shinagawa Fuel Co., Ltd. to Sinanen Co., Ltd. (now Sinanen Holdings Co., Ltd.). In October 2015, with the transition to a pure holding company structure, the company changed its trade name from Sinanen Co., Ltd. to Sinanen Holdings Co., Ltd. According to the company's investor-relations history page, the group has delivered energy, housing, and lifestyle services attuned to the times and society since its founding in 1927, and in 2015 it moved to a pure holding company structure and began challenges toward realizing a decarbonized society; in 2026 it plans to integrate four core companies and revise its group logo and MVV, heading toward its 100th anniversary in 2027.
