Overview

Marufuku Yushi Kogyo Co., Ltd. is a Japanese company based in Sanjo, Niigata, founded in 1932 by Rokuro Sasagawa. It manufactures household powdered soap, liquid soap, and cleaning agents made from plant oils, as well as barrel-polishing detergents and other household toiletry products.

History

The company was founded in May 1932 (Showa 7) by Rokuro Sasagawa as a sole proprietorship in Sanjo City. In September 1941 (Showa 16), it was reorganized into Niigata Prefecture Soap Industry Co., Ltd. through a corporate merger. In 1948 (Showa 23), it absorbed Marufuku Chemical Industry Works and changed its name to Marufuku Yushi Kogyo Co., Ltd. Subsequent milestones include receiving the Niigata District Invention Award from the Invention Association Niigata Branch in 1967, and receiving development funds from Sanjo City for improvements in soap manufacturing in 1980, for a 'garbage deodorant' in 1989, for a 'food waste oil treatment agent' in 1990, for a 'hair decomposition agent' in 1993, for a 'waterproof spray' in 1994, and for a 'snow melting agent' in 1999. In 1989, it also received a development subsidy from Niigata Prefecture for an 'edible oil recycling cartridge filter'. In 1994, the company increased its capital by 5 million yen to 15 million yen.
