It would be "omiyage" you're refering to buying. Buying a couple Americany gifts maybe 5$-10$ at most would not be a bad idea even for a vacation when you are planning to return later. Makes a good impression from what I have heard from friends who have gone.
I'm still not sure what omiyage I will get for my host family, other than mugs, some american wine, or other random gift things. This wouldn't be a bad spot on a thread like this to list good omiyage ideas.
I'll put down my idea of T-shirts or Mugs with sayings on them.
(I don't think he meant to randomly give gifts, but a couple cheap presents would be a good idea to bring I think.)[/QUOT
What is your host family? How do you get one? Also, if I make friends in japan, could I give them a gift?
