The bad things Nintendo do, like the lawsuits, the music take-downs on YouTube, censored localization and so on, usually come from Nintendo of America. From Nintendo of Japan only good things come out, like the gigaleak (and eventually some games).
on side note, the former Nintendo of America CEO released a book where he tells that everything that went well was his idea, and everything that went bad he warned the Japanese about, but they did anyway, so self personal promotion is also a Nintendo of America thing apparently.
