I went to Ameyoko
Everyone seemed to be enjoying drinking in the evening.

Ameyoko is the official name of Ameya Yokocho, a shopping street with about 400 stores located mainly on the west side of the Yamanote Line viaduct between Okachimachi Station and Ueno Station and about 500 to 600 meters under the viaduct.
The area is crowded with tourists during the day.
