What is there to do in Tokyo?

Travel Info
Planning a week trip to Tokyo. What sites does it have to offer for an anime fan. I know I will have fun no matter what I do, I mean Japan, come on, but I want to get the most out of my trip. Any suggestions?

You should plan a trip to the 3D theatre here.. very cool!
As with most Japanese websites, you lose a lot of great info when you have to go to teh englih site. Do you have someone who can translate the Japanese site for you?
It will help with the map as well.
Also, here is the site for the Anime Festival in 2008. (you missed 2007 already.. maybe you can catch it next time!)http://www.tokyoanime.jp/en/

Sanrio Puroland AKA "the Hello Kitty theme park" and Akihabara would be good spots to check out. Puroland actually has an English website.
