A large square tumulus of the first half of the 7th century. The city explains that from the late 16th century through the 17th and 18th, potters from nearby kilns reused the stone chamber as a workshop and the like. When that use ended, it became a place of prayer to Toso-shin, the deity of potters, and to a mountain deity, and the rites continue to this day.
