After the war, an ocean going shipping business was considered as a military industry and Saburo Yamashita was purged from an executive director position of Yamashita Steamship
Company. In December,the Yamashita family was designated as a zaibatsu (family-run conglomerate) by the occupation forces and the family's assets were frozen.
With the above background, two brothers, Saburo and Haro Yamashita, established Kashiwa Company. Carbon dioxide fire extinguishers comprised its main line of business at the initial stage. Later, their youngest brother, Toyoro, joined the company.
The purge was released and Saburo went back to Yamashita Steamship Company and became its President in 1960. Merged with other companies, Yamashita Steamship Company later became Yamashita-Shinnihon Steamship Co., Navix Line, Ltd., and now Mitsui O.S.K. Lines.
