Planned to be released by the end of this year, Bayonetta 3 has passed the rating examination in North America and according to the Nintendo’s official site page it’s classified as M (mature) due to the violence, blood and gore, partial nudity and strong language inside the game.
Considering the M rate corresponds to CERO Z in Japan, there are good chances that the Japanese version will be also censored due to the strictly rules of the CERO association.
