In just Tokyo or the entire country? I live in Tokyo so other places with the exception of Shibuya I know nothing about. Obviously there is sushi (lol), different kinds of soup, different kinds of fish, ramen and there's some more but can't remember them. Those are just a few that I know lots of people eat mostly every day. There's lots of place you can visit such as historical sites from a very long time ago. There's also a park that you could check out. There's also a shopping mall that has close to 200 stores (just an estimate), is two levels high and I think there's an indoor amusement park too. One of the stores in the mall is called Pokémon Center. I've been working there for two and a half years now. The store has lots of different merchandises such as keychains, iPhone covers, plushies, trading cards, posters, mugs, DVDs, etc. Those are what I can remember right now lol. Umm... Anything else you want to know?
