There are many exciting spots in Tokyo and its vicinity. Why don't you create your own tour by combining some of them? Guide can assist you in advance. One of my suggestion is as follows: National Museum in Ueno Park, Asakusa, FukagawaFudodo temple, TomiokaHachiman shrine and Ginza street. National Museum has an excellent collection of Japanese culture. Asakusa is one of the most popular spots and you can enjoy shopping souvenirs and meet many ordinary folks. At FukagawaFudodo temple you can attend a "Goma" Ritual Service of Shingon Esoteric Buddhism. It must be a very impressive experience for you in Japan. You can understand some aspects of Japanese culture and spiritual life.
