Each area has its own distinct culture and history. Shibuya, Ginza, Asakusa, Nakameguro, Akihabara, Kagurazaka...Tokyo truly is a world class unique city. (The only other places I felt similar was in New York and London!) I try to do some research before I check out a new spot, and the deeper I delve into one area, the more exciting it gets!
