I think they blur ir after. Just Japanese law prevents the showing of genitalia. Not other parts of the body. So only the vagina and penis are normally censored. However is some cases the asshole is censored too but it's not as often I don't think.
Asshole has to be censored when it's being penetrated afaik, though sometimes they just censor it along with the rest for whatever reason, probably less effort to draw.
