Well, I do not speak any Japanese or Chinese, but I think that's most likely the case. Why do I think that? I have been in Tokyo for the past week, and already spent 3 weeks here last year, and one of the things I've noticed is the funny t-shirt texts in English. Their knowledge of English language is probably close to our general knowledge of Japanese, so... you have a mess.
Things like "Behave me", or "All we need it love, is we need", or even "Laughing got tired", are very common here. I already got two of those shirts. They are awesome! :)
