Man, I'm sorry I missed this thread! Late to the par-tay, as it were.
A few things worth mentioning:
tetsuo - as DC said, there are tons of brands of condoms in Japan. Sometimes when you talk you tend to speak really authoritatively, but in actuality, you're wrong -- this is a bad habit and one you should break ASAP

(friendly advice, don't take it personal)
jonny - I have to agree that Japanese do not sweat as much as Westerners do. That's not to say they don't sweat at all -- BUT -- even when they do sweat, they generally don't stink, which has a lot to do with their diets. (BTW, I take showers every day too -- do you British folk do the fortnight thing, or...?

)
bebpo - we used to have trash cans everywhere! then some asshole left a bomb in one. japan likes to overreact to these situations, you see. thus, you no longer find trash cans ANYWHERE (sigh...)
borghe - I know you're already here, but, if you see this -- I hope you have a good time in Japan!!
