What are the tourist spots in Japan i shouldn't miss going?

Wow, that's great! I've never gone to Tokyo yet, though I want to. Here, it's a link about some good information on places to go: http://wikitravel.org/en/Tokyo If I were you, I'd also visit the Akihabara, lol. So many technology in one place, it's delirious. But only if you're into hi-tech stuff, lol.
