On a hilltop among the Stone Buddhas of Usuki is a small Hiyoshi Shrine. One of about 4,000 Hiyoshi Shrines around the current, it is a branch of the famous Hiyoshi Taisha at the base of Mount Hie near Lake Biwa.
Originally called Hie Shrine, Hiyoshi Taisha was the protective shrine for the monastic complex of Enryakuji on top of Mount Hie, and so I suspect that the monks who carved the Usuki Buddhas were of the Tendai Sect.
The woods around the shrine are apparently quite unique and listed as a prefectural nature site.
The wooden komainu were quite unusual and the honden had some nice relief carvings....
