On the banks of a ditch fed by three springs,fist-sized stones were laid.

This is a large ditch built around the second half of the early Kofun period (late 4th century). Of the three springs at its upstream end, two have box-shaped stone frames, and at a confluence stones about 50 cm high were set upright. The Agency for Cultural Affairs considers that rites were held here, with the spring water itself regarded as sacred.
