I love going to supermarkets in different countries, it's a wonderful way of learning about cuisine, even if you can't read what certain things are. Japanese supermarkets are cool.
Teeny tiny fish that we put in the somen noodles:
Teeny tiny beer! (seriously, who drinks 135ml of beer??)
Teeny tiny sake
And, beer for children. It's non-alcoholic, but foams up just like the real thing...
Supermarkets are fun!
