The Japanese wrinkled frog is a true frog native to Japan and introduced to Hawaii in the late nineteenth century. It and its close relative are distinguished from other frogs by rough, uneven skin. It lives and breeds in various freshwater environments, including ponds, streams and wetlands (Wikipedia, general species account). The source does not describe its status in China.
