The Japanese do not like to "rock the boat"... so if something is likely to be considered tasteless or extreme: it generally doesn't get airtime. But the Japanese are quite a bit less uptight about nudity and bodily functions than people in the West: so some things we might consider shocking or in poor taste are perfectly fine.
