[2] Constructing Buddha statues out of stone is widely practiced in Buddhist areas in Asia.

There are no historical materials remaining that testify to the period or circumstances surrounding the construction of these statues.

With the decline in Shugendō pilgrimages from the Muromachi period onward, the statues were forgotten and remained exposed to the elements, some of them possibly for over a thousand years.

The replica of the Buddha's head on the platform of Usuki Station was made before the restoration, and is a good representation of the state it was in when it was placed underfoot.

[3] The surrounding topography, which had been a V-shaped valley, was destroyed during conservation and restoration work, and the portion of wall on which the stone Buddhas were not carved was cut down.

Drainage facilities have been introduced around the carvings, so there is no longer any possibility of water flowing at the feet or underneath the stone statues.

[3] The site is approximately 4.5 kilometers southwest from Kami-Usuki Station on the JR Kyushu Nippō Main Line.
