It's a feature of November. What is this place where the go board is placed?
The radiant ceremony "Sevengosan Fukasogi's ceremony"
The location in the photo is Nihonbashi Hie-jinja Shrine.
The go board installed on the precincts is used in Shichigosan's "Fukasogi no Gi".
According to the story of the shrine, a child who prayed for Shichigosan jumps from above this foundation to Yoshikata and wishes for health and growth.
※I remember that the Yoshikata is south-southeast, but please check the direction of flying at the shrine.
It is a feature of November every year, and you can see it when you visit the shrine at this time (10:00 to 16:00).
