The Japanese let volunteers from Okinawa into their army since 1890 and in 1898 Okinawa was given universal military conscription and were parts of all arms of the Japanese military, unlike Koreans where there was no conscription until the very last year of World War II since the Japanese did not trust Koreans unlike Okinawans. Taiwanese were also distrusted by the Japanese, with volunteers from Taiwan only allowed in 1942 and conscription only implemented in 1945.
