Anime is animation originating from Japan. Outside Japan and in English, anime refers specifically to animation produced in Japan. However, anime, in Japan and in Japanese, describes all animated works, regardless of style or origin. Many works of animation with a similar style to Japanese animation are also produced outside Japan. Video games sometimes also feature themes and art styles that may be labelled as anime.
