Hi,
At the end of my third year as a teacher on the JET program (at the bottom of Mt. Fuji), I find that I pretty much always have a different perspective than Jordan when it comes to things in Japan. Still, I greatly respect what he's doing with this column, and I hope he keeps it up.
Since I teach for JET, I'd like to respond to the question about long hair: it shouldn't be a problem*, so long as you are professional about the rest of your appearance. While you'll definitely won't make any waves if you have short hair, wild, anime-esque hairstyles are pretty common over here. A lot of young men in Japan have what I would term longish hair, even some who are in the business world (though usually not below the shoulders). About half of my male junior high students are sporting hybrid mullets at the moment. I know a few JET guys who have hair down to the middle of their backs.
Anyway, anyone with questions about the JET Program or who wants another view of Japan (with not much about games or anime, I'm sorry) can email me or check out my blog (below).

*Attitudes about hairstyles and attire would vary if you were placed with a very conservative region or if you were working for a private organization, so I'm not making any promises.
