...However, some scholars distinguish between Japanese and continental pheasants as separate species. Japanese pheasants are divided into four subspecies: Northern pheasant (northern Honshu, Sado), Tokai pheasant (central and western Honshu, Shikoku), Kyushu pheasant (southern Honshu, Kyushu, Goto Islands), and Shima pheasant (part of Honshu, Yakushima, Tanegashima, Izu Islands). However, because pheasants are game birds, each prefecture has artificially bred and released them every year, resulting in the various subspecies being mixed together in various places, and the differences between the subspecies are no longer clear. *Some of the terminology that refers to "northern pheasant" is listed below.
