Not that it really matters, but yeah, I think he's Japanese. His English patterns are, based on my experience, pretty typical of a Japanese person with a limited grasp on English. Before you jump on me about that, know that Japanese grammar is vastly different from grammar structures for English and other romance languages, so when someone goes from Japanese to English with a limited understanding, it's pretty distinct.
That aside, I think his nationality and, honestly, his intentions, are beside the point. The point is, it is way too soon to do something like this. Not just because there are people still suffering from this tragedy, but because - and this is perhaps most important - this tragedy is still in danger of becoming much, much, much worse. Earthquakes continue, literally, daily here in Japan. There are several a day, as the tectonic plates slowly try to return to their normal state, and one of these days soon one of those earthquakes might, just might, cause a tsunami that wipes out the workers trying to fix this reactor problem... and without those workers on site, all of those reactors will explode and cause both local and global effects that history has heretofore never seen.
That is why, regardless of intentions, nationality, and logic, this is way way way way way too soon.
