South Seas Development Company
The South Seas Development Company (Nan'yō Kōhatsu) was a Japanese colonial company founded in 1921 by the businessman Matsue Haruji to develop the South Seas Mandate. It built sugar plantations and refineries on Saipan, Tinian and Rota, worked mainly by migrants from Okinawa and Japan, and later expanded into phosphate, fisheries and trade across the Pacific and South-east Asia. It was dissolved after Japan's defeat in 1945.
