My trip report's kind of a slog, but if you skim through it, we spent about 10 days in Tokyo and crammed so much fun stuff into every day. Here's the link:

Off the top of my head, some ideas are...
- Visit Tsukiji Fish Market
- See Kitchentown and the stores where they sell the fake food restaurants use
- Tokyo City View at the top of Mori Tower
- Tour the Imperial Palace - you have to apply to go, but it's free:

- Walk across Shibuya crossing (the main drag in "Tokyo Mater") at night when all the neon's lit up, then go visit the statue of Hachiko the Dog.
- Visit Ueno Park for its museums, lakes and zoo
- Wander around Akhiabara looking for anime stuff
- Check out the huge toy stores like Kiddyland in Harajuku and Hakuhinkan Toy Park in Ginza
- Go to the ginormous Sony store near Ginza and play with all the gadgets
- Window shop Ginza (like Rodeo Drive) or Harajuku (like... Melrose?)
- Visit a cat cafe and pet kitties
- Ride the monorail around Odaiba and get off at some of the museums or the Toyota showcase, where you can go on rides and stuff.
- Visit the original Mitsukoshi Department Storeif you get there when it opens there's an organist playing the pipe organ and all the sales clerks welcome you as you walk the aisles.
- Do karaoke
-
Get a bunch of crazy unfamiliar food from a department store food hall or just 7 Eleven and eat it in your hotel room in front of Japanese TV
- Take a day trip to Hakone or Kyoto (Hakone is closer so it's cheaper)
