You shouldn't spend too much energy thinking about translating your game into a language you don't even know yet. Also note that Chinese, Korean, and Japanese are completely different languages. Linguistically speaking, Dutch and Hindi are more similar than are Chinese and Japanese. Having said that: From my very limited knowledge, a system structured like the one you propose should be translatable into Japanese. So just go for it. You can worry about rain once you have the sky in place.
