The eastern buzzard or Japanese buzzard (Buteo japonicus) is a medium to large bird of prey that is sometimes considered a subspecies of the widespread common buzzard (Buteo buteo). Some scientists treated is as a distinct species starting in 2008, but others still treat it as either one or three subspecies. It is native to Mongolia, China, Japan and some offshore islands. At least some birds winter in Southeast Asia. It is similar to the steppe buzzard. It is carnivorous.
