Well there's there's the Kaminarimon Dori in Asakusa, which is in the older part of Tokyo. That's the largest temple gate in Tokyo.

Mistukoshi in Ginza district is a major high-end department store, which in itself isn't cool. But it's historically significant since Mitsukoshi is the oldest department store franchise in the world, dating back 400 years to when they first just sold kimonos at a static price in a static location. I think the store actually may even been on the grounds of the original store.

The Kabuki Theatre, which I think is around Shinjuku District is very cool. It's really cool architectually. You can also pay something like 700 yen to catch an act out of a Kabuki play, which will run for about an hour.

The Edo Tokyo Museum (can't remember exactly where that is) is a really cool museum that shows the history of Tokyo. When you head up the escalators, you can hire yourself a free English tour guide. They're great because they're so informative, and they provide the service free simply because they want to practice their English. Just outside the Edo-Tokyo Museum is the Sumo arena, which if you're lucky is holding a match. Though I think it's too late in the year for that.

In my opinion, Tokyo is fun not so much because of its historical significance so much as it is about getting a glimpse into modern-day Japanese culture. If your looking for sites of more historical significance, you're better off hitting Kyoto.
