I'm going to see some relatives in Japan, and I wanted to bring them some gifts from America. What are some American products that Japanese people would appreciate? Conversely, are there products in Japan that aren't available in the U.S., which would make good gifts for my American friends and family?
You never mentioned how old the people you are buying gifts for, so I'll have to tell you what I took.
When I travelled to Japan, I brought things that were uniquely Canadian (maple syrup, smoked salmon, etc). I also took little Canada pins to give out, as well as things like shirts from my university, city, a hockey stick, hockey cards, etc. Basically, I brought stuff that was from Canada and wasn't perishable.
The dollar store at the mall likely has tons of great stuff, from coffee mugs/key chains/etc with your hometown's name on it.
My advice is to bring stuff that is a regional specialty, like California wine or salsa from the SW or maple syrup from New England...hope that helps. If you send me a detailed message, I'll be glad to offer up some more ideas.
