Whatever OP says there must be something that's typical about her country. It sounds like you live in Switzerland so bring them coo-coo-clocks, knives and toblerone (you get the picture).
Alcohol is pretty good though, but you have to make sure that the receivers like to drink. It seems as though a proportionately higher amount of Japanese don't drink at all as compared to Europeans.
I also recommend bringing some postcards or similar of beautiful sights etc. in your home country. These are good tiny gifts for random people that you meet, where it's the thought that counts most of all.

Hope this helps.
