Business in Japan. You can't believe all the sightseeing I won't be able to do. I'll be mostly in the Kansai area, which, is somewhat different from the Kanto area as Wikipedia notes. Especially there's a difference in personalities between the two; it's as though one region was like Brooklyn (Kansai area) and the other was more like ...well...whatever place in NYC accountants work (maybe Hartford CT)...the Tokyo region is somewhat like a whole NY full of accountants and insurance salesman.. That's a horrendous and crude over-generalization, but there clearly is a difference in personalities in the two regions, and even an inexperienced foreigner can see the difference first-hand. Perhaps more to the point: Osaka is like a whole more like NYC's Times Square, and Tokyo is much less so, save for Shinjuku, Roppongi, Shibuya, Asakusa and places like that.
If I get a chance maybe I'll blog a few pictures but chances are verbal content might be a tad sparse over the coming week.
