Nintendo JP claims they will not be censoring third party Switch games, as it inhibits the industry
As of late, the gaming industry has gone through a rather topsy-turvy phase, with Sony cracking down by censoring or banning certain themes within video games, while Nintendo, usually thought of as the more "censorship-happy" company, has been allowing games on their platform without removing content. The most recent case of this being Super Neptunia RPG, which had two CG scenes edited in the release on PlayStation 4 as opposed to the Switch version, which was untouched. This topic was brought up during Nintendo's 79th Shareholder's Meeting Q&A, where Nintendo president Shuntaro Furukawa reiterated Nintendo of Japan's stance on censorship, claiming, "Nintendo, as do third parties and their software, applies for an objective rating from third-party organizations (CERO) prior to release. If platform-holding companies choose arbitrarily, the diversity and fairness in game software would be significantly inhibited. We provide parental controls that can be used to apply limits." (translation courtesy of Censored Gaming.)
Furukawa further added that, "Nintendo, at this time, does not censor, and does not intend to censor", when it comes to third-party releases on the Nintendo Switch. Whether this stance may also apply to Nintendo of America and their localization Threehouse branch, is dubious, with western first-party titles like Xenoblade Chronicles X, Fire Emblem Fates, and Tokyo Mirage Sessions having seen controversial censorship choices in the past. But as it stands, it appears that software from other publishers will remain uncensored, for the time being.
