"Chinowa" is a large ring made of grass and erected on the pathway leading to a shrine on the days of purification (harae). Photos are taken at Shinagawa Shrine.

 

At the shrine, you can pass through the ring as an act of purification from misdeeds (tsumi), impurities (kegare), or bad luck.

Shinagawa Shrine is located only a few minutes away from Shim-Bamba station, Keikyu Line. (5 minutes from Shinagawa Station) When you go up the stairs, you can see whole Shinagawa area.

 

They also have a mock Mt. Fuji (a little hill you can climb up by steep stairs). Japanese people worship Mt. Fuji and there are about 60 mock Mt. Fuji spots in Tokyo for those who are not able to climb up the mountain.
This shrine is calm and peaceful. Very special place! Worth a visit if you are in the area.
