What is Sengakuji and where is it located?

Sengakuji is the name of a small town in central Tokyo near Shinagawa station, but it is perhaps more globally recognized as the town where “Sengakuji Temple” is located. The Sengakuji Temple, founded in the 17th century, has become one of the most popular and famous buddhist temples in Japan for the final resting ground of the “47-Ronin”, the masterless samurai from Akoh in the Western part of Japan, all of whom dedicated their entire life to their master…until death.

The redevelopment area unilaterally proposed by SUMITOMO (without consent of landowners) is an area adjacent to this temple, where a total of 260 property owners live.
