Effectively nobody in Japan uses or even knows the kana keyboard layout though, only QWERTY. My comment was more that they may not know the word "quit" for the Q to be meaningful to them... not that they can't find it on the keyboard.
Similarly as an English speaker I would be quite confused if the shortcut key for exit was a totally different letter like P or something.
