The Japanese tit (Parus minor), also known as the Oriental tit, is a passerine bird which replaces the similar great tit in Japan and the Russian Far East beyond the Amur River, including the Kuril Islands. Until recently, this species was classified as a subspecies of great tit (Parus major), but studies indicated that the two species coexist in the Russian Far East without intermingling or frequent hybridization.
