The outlying cities, Nagoya, Nikko, & Kyoto especially are 'fantastic' for their ancient temples & scenery, though Tokyo does have the Emeror's palace right in the center of the city and is great as well. From atop the Tokyo Tower, you get a great 360 degree panorama view of the city & also of Mt. Fuji in the distance - there are telescopes to provide 'close-up' views.
Springtime is probably the best time to visit - around Easter when the cherry trees are in full bloom, though I can imagine the Fall colours must be spectacular as well.My favorite memory of Japan is of the Temples & park-like region of Kyoto.
