Oh also I'd recommend visiting Tsukiji fish market. Its a very cool place to check out and you can get your sushi fix with some of the freshest fish you'll ever get for sushi. And some advice, don't be a stupid tourist who makes your country look bad. I've seen plenty of them, mostly in Tokyo, and they give the Japanese the stereotypes that they have of other countries. They actually closed of the giant tuna auction is Tsukiji for about a month because of rude tourists, such as thinking it would be funny to bid on the fish and taking flash photography during the auction, but recently reopened it because its way too valuable for tourism. Just don't be a loud obnoxious jerk and you should be fine.
. Shinjuku is also a really cool place to hit up. Tokyo Tower is pretty cool so I'd visit that as well. Harajuku is pretty cool for clothes if I remember right but may be wrong there. The giant shrine in Asakusa is pretty cool too. Just explore as much as you can. There is so much to Tokyo and you can find some really awesome places just by lookin around. If you like clubbing definitely go to Club Ageha or Club Asia. They are both really awesome clubs. Ageha is the largest club in Tokyo but from what I've heard its kinda hit or miss. Night I went it was packed but other nights it can be empty from what I've heard. Its also the younger crowd as in like 20-22 where Club Asia gets the older crowd. Sometimes its just fun to get on the JR line and get off at a random stop and check out some random part of Tokyo. Me and a few friends did that one time and it was pretty cool. I only really know about Tokyo and Sendai as Sendai is currently where I'm livin. Hope this helps
