Visiting Japan

On June 8th, I will be part of a short-term exchange program, in which I will travel to Japan for two weeks, living with a Japanese family during that time. The trip itself is somewhat planned out, but for the first three-four days, I will be able to do anything (within reason) I want with them.

My questions:

1) Any suggestions on what I should do? (Going to Himeji if it helps)
2) Anything I should definitely get while there? (I will be going to a mall there)
3) Are there any useful phrases I could use with them?

you're already gone, but try hitting a night club over there. if u can get to osaka or tokyo (even kyoto or nagoya). it seems that the kinki area has more psytrance/dnb where as the tokyo area tends to have trance and gabber

this is just from my experience though
