I typed a long rant. but.. deleted.
After 5months here in Tokyo, I have found many things I don't like about Japan.
But, it shouldn't scare you off.
You don't learn these things unless you come here. It is something to get away from America, and to be in another country.
JET pays more, but they send you to bumblefuck.
NOVA and berliz can get you a job closer to Tokyo (not sure if that is a good thing).
I also know a small english school just outside Tokyo (in Chiba).
I think the english teaching jobs are kinda shit though, and seem boring.
It is better to come as a student, if you can.
Most of the black people I have met in Japan are shady as hell. They are from like Africa or somewhere, but they dress in American hip-hop styles and ask me in a horrid accent to come check out their 'young girls" and 'free drink free touch' for 19min. for only 3000yen.
No one is going to attack you because you are black.. but expect lots of dumb questions and shit...
