This is the third (and oldest existing) underground mall in Japan.
When it was built in 1955, Asakusa Underground Mall became the third such structure in Japan, and it is now the oldest remaining. The mall is filled with a nostalgic atmosphere, as if you had traveled back to the Showa Era (1926-1989), with bare pipes on the ceiling and water leaking onto the floor. The 23 shops here include a very cheap barber (haircut: 700 JPY), yakisoba eatery (one plate: 350 JPY), DVD shop, Thai restaurant, sundry goods store with permanent discounts of 50–90%, fortune teller, Qigong shop, and printing shop. Each one is small (33 square meters) and fun to explore. A two-minute walk from Asakusa Station on the Tokyo Metro Ginza Line.
