No, it does not make sense to go to any other city. Tokyo has enough to keep a person busy for a lifetime. If you want to see Kyoto, fly into KIX instead and take the Haruka express train to Kyoto. (Kyoto does not have its own airport.)

There are at least four publishers that produce guidebooks for Tokyo (and Kyoto), and they're usually available at your nearest large bookstore or in e-book form.

Also, there are dozens of threads about Tokyo in this forum. If for some reason you can't or don't want to buy a guidebook, start there.
