Amercan and Hawaiian colonists started settling the Bonin islands in 1830. In 1853, Commodore Perry acquired property on Chichijima and named a governor for the new US colony of Peel island. After World War II, the islands were returned to Japan. Some of the residents claiming American descent were repatriated back to the US.
