...this post is kinda ridiculous considering it's a non Japanese person giving "notes" so people who are also not Japanese can create Japan or Japanese people in... fanfiction... some of these are completely dumb and stereotypical... and their sources are three YouTubers..eye.. https://twitter.com/Tomo_todomomo/status/1253709184320716803

that being said there's nothing wrong with writing Japanese people or setting your story in Japan... but this ain't it.
