Did you know that the word “Hentai” differs in meaning between English and Japanese?
In English, Hentai refers to the pornography with Anime or Manga styling, but originally in Japanese, it means “changing shapes” or “abnormal sexual desire”
So if you want to look for Hentai in Japan, you should rather refer to words like “Ero-Anime” or “Nijigen (Two dimensional) Ero” in adult comic shops!
