The island remained uninhabited until claimed by the Empire of Japan in 1885. In 1900, a team of pioneers from Hachijōjima, an island located south of Tokyo led by Tamaoki Han'emon (1838 – 1910), who had pioneered settlement on Minamidaitōjima, became the first human inhabitants of the islands, and started the cultivation of sugar cane from 1903. During this period until World War II, Kitadaitōjima was owned in its entirety by Dai Nippon Sugar (now Dai Nippon Meiji Sugar), which also operated mines for the extraction of guano for use in fertilizer. Many of the inhabitants were seasonal workers from Okinawa and Taiwan. After World War II, the island was occupied by the United States. The use of increased mechanization increased phosphate yields marginally until the deposits were exhausted by the mid 1950s. The island was returned to Japan in 1972.
