Shot at Seifa-Utaki, an old holy place of Ryukyu dynasty in Nanjo, Okinawa. There were a number of sacred places in the precinct. And this place was the most sacred place among the other places. This place was called 'Sangui'.
Two big rocks were there and they made a big triangle. The triangle was enough big to go through. When I stood in front of it, I could see some figures standing on the other side of the rocks. Once it was prohibited to enter for the ordinary persons. Yet it became a tourist attraction. I didn't know whether the deities enshrined here enjoy the tourists coming or not.
