If you're into plamo, I wish I could remember the name of the shop in Akiba I stumbled upon when I went in '09. I remember them having several new or recently released kits (where I got my Aoshima Garland and Bandai R3 Layzner) but they also had a treasure trove of really old kits (like my DYRL Strike Valkyrie for ~250Y) for dirt cheap. Had I more room (or less manga) in my suitcase, I probably would have picked up more stuff there than I did. If you're not into plamo, I think I remember a couple of display shelves that were worth a peak. If I remember, it was the place with the large Mazinger Z outside but being nearly 10 years ago now, who knows what's happened in the meantime.

Things I often recommend:
I'll second Akage's suggestion of Mori Tower in Roppongi/Roppongi Hills (Minato-ku Roppongi 6-chome 10ban-1gou) - hit the observation deck on 50-ish and you can get a 360 degree panorama all around Tokyo (at least). While Tokyo Tower is prominent in anime, the only pics I have of it are from above in Mori Tower. Website doesn't say how much the tickets for Tokyo City View are, but I don't remember it being more than 3000Y. I've paid more for other observation decks in North America.
If you're travelling within the country, I'll be the weirdo that recommends staying in a capsule hotel, especially if you're in between stops. By far one of the most fun and unique travel experiences I've had. I wouldn't try to book my entire trip in capsules but it made a lot of sense when I had a very early flight the next morning and the friend I was staying with didn't live in the city I was flying out of.
Last but not least, a Nippon Professional Baseball game. Even if you don't like baseball, the crowd and cheering sections/ouendan are usually really into it and makes the whole game a spectacle. If you're in Tokyo, you might save yourself a bit of money and opt for a game at Meiji Jingu Stadium where Yakult Swallows play, rather than drop bigger money on a Yomiuri Giants game. Tokyo and Osaka/Kyoto/Hyogo have a couple teams between them but there are a few other designated cities and large cities that have franchise teams, depending on where else in the country you are thinking about heading.
