There's no livelier introduction to Tokyo's neighborhoods than Asakusa, with its old shitamachi (downtown) atmosphere and the city's oldest temple. After wending your way along Nakamise Dori, a pedestrian lane lined with stalls selling rice crackers, fans, umbrellas, T-shirts, cotton kimono and other souvenirs, you'll reach Sensoji Temple, founded in the 7th century and home to the Goddess of Mercy.

Tokyo is Japan's economic and cultural center. Vibrant neighborhoods and fantastic cuisine are around every corner. This mecca of Japanese pop culture fused with traditional ideals is one of the world's most entertaining cities.
