This species was formerly found in Japan's Ryukyu Islands, but it has not been recorded since 1936 and is now Extinct. The reasons for this are unknown.
None remain, a dramatic decline to extinction occurred from the late 19th to the first half of the 20th centuries.
Columba jouyi was endemic to Okinawa and Kerama, and the Daito Islands, in the Nansei Shoto Islands, Japan (Stattersfield et al. 1998). It was described in 1887 from a type in the Tokyo Educational Museum (Stejneger 1887), and is also known from three skins in Tring (Knox and Walters 1994). It apparently declined rapidly (and inexplicably), and was last recorded on Okinawa in 1904, and on Daito in 1936 (Stattersfield et al. 1998).
It is likely to have inhabited the forested interior of the islands on which it lived.
It is not known why it became extinct.
