Manga are a kind of comic, they’re just pretty specific about their format and choices. Anime is a kind of animated cartoon, it’s just specific about its choices. Even “coming from Japan” isn’t a requirement as long as it follows those traditionally(-ish) Japanese choices.
Eh, there’s different schools of thought. Artists like Junji Ito or Kabi Nagata make stuff very different from the usual manga, but they’re still called “manga”. In the same way, Radiant isn’t considered a manga by many even though it’s so close to the actual ones it even got an anime.
