Earlier today, I found a bug in Discord where one of the login forms in Japanese uses 「はい」 ("Yes") as the label for the "Log in" button. The button in question is right beneath a label stating 「パスワードをお忘れですか」("Forgot password?").

X / Twitter is full of funny translations, too. My favorite is 「ポストさんを報告」 (lit. "Report Mr. Post").
