Tachibana Michiyo's tomb (橘三千代の墓) is located in a secluded mountain, which looks like an underground temple.
On the other hand, the underground temple of the cross of Empress Kōmyō (光明皇后), the daughter of Michiyo, was built to face the Atago Shrine (愛宕神社) (Mt. Atago).
There is a place in Wazuka-Town (和束町), where a right triangle, especially the Kepler triangle is formed from the two points of Mt. Atago (愛宕山) and Tachibana Michiyo's tomb, and at that place, a huge sacred rock (Iwakura) seems to exist as a benchmark.
There is no information about its location on the internet at all.
So today, I'm going with Mr. Takebe to investigate the sacred rock formation.
I will check with my own eyes what's there or nothing is there.
