Shinagawa Shrine
Shinagawa Shrine was founded in 1187 as a place for marine traffic safety and prayer realizations. During the shrine’s annual festival, which takes place in early June every year, portable shrines called “mikoshi” are carried around town, and many people come to celebrate.
You'll find this shrine south of Shinagawa Station. It has an impressive street entrance and a set of steep steps. The shrine itself is pretty small.
