The island remained uninhabited until claimed by the Empire of Japan in 1885. In 1900, a team of pioneers from Hachijōjima, one of the Izu Islands located south of Tokyo led by Tamaoki Han'emon (1838 – 1910), became the first human inhabitants of the island, and started the cultivation of sugar cane. The population reached 4000 in 1919. During this period until World War II, Minamidaitōjima was owned in its entirety by Dai Nippon Sugar (now Dai Nippon Meiji Sugar), which provided community services and subsidized pricing for its employees, and of whom were seasonal workers from Okinawa and Taiwan.
