The Sugao stone Buddha statues were created in the late-Heian period. The area was designated as an archeological site on 22 January, 1924, and as an important cultural asset on 26 May, 1964.

There are five carved images: Amitabha Buddha in the center, Bhaisajyaguru and Sahasrabhuja-arya-avalokiteśvara on the right, and Jūichimen Kannon and Tamonten on the left. They are preserved in relatively good condition. From the red-colored images, an invisible energy seems to gush out.

For 1000 years, these monuments have been protecting the people from mishap, while bringing luck and encouraging the birth and raising of strong children. The statues are also called 'Iwagongen' as an invocation to the god Kishu-Kumanogongen
