    Tomb of Tani Shigeto

    Tani Shigeto, whose surname was Jinzan, was born in 1663 as the third son of a Shinto priest in Oko Hachiman. He studied Neo-Confucianism, Shintoism, national history, astronomy, and calendar studies, and had a promising future. But at the age of 45, he was falsely accused and imprisoned here. He died in 1718 at the age of 56, but no tombstone was made, following the Tani clan's admonition that "enlarging the grave will eventually destroy the family."

    Nonaka Shrine (Oendo)

    In 1708, after Kaneyama's death, his fourth daughter, En, built an ancestral shrine with Mr. Furumaki (Kaneyama's former vassal) in order to enshrine her father. This Nonaka Shrine is called Oshido, and has a quiet appearance that retains the vestiges of those days.

    Eigenji Temple

    It is said to have been founded by Yamauchi Bingo no Kami Hikosaku, a chief retainer of the Tosa domain. The principal object of worship is Avalokiteshvara, and it’s the 33rd Avalokiteshvara of Tosa Province and the 11th Sacred Site. In the past, it was a subdivision of Eiheiji, the head temple of the Soto sect of Buddhism, and was called Kanonji, serving as a temple to ward off demons. But after Tosa came under the rule of Kazutoyo Yamanouchi, it became Furumineyama Kanryuji Temple. It was destroyed by fire in 1708, but was rebuilt as Eigenji Temple the following year. In the back, there are 10 tombstones called "egg towers", which are the graves of the Inui clan, chief retainers of the early Tosa domain.
