So, I'm a student right now and I'm really busy, but I could probably help translate a little bit into Japanese if there's anyone else interested in helping? I couldn't make the language as flowery as the English version, but I wouldn't have any trouble getting the meaning across. I don't think I can commit securely to any large additional amount of work during the semester though, so I wouldn't be as reliable or useful as someone else might be. Another problem is that I'm not a member or any Japanese fan communities, but I just scanned some Japanese pages and wikis, and I don't think I'd have much trouble learning all the relevant jargon. Are you also interested in reserve volunteers of some kind?
