The Sainoo Temple site, located in the San’in region (encompassing present day Tottori, Shimane, and the northern part of Yamaguchi prefectures), was one of the preeminent ancient temples in that area. It is laid out in the style ofthe grounds at Hōryū-ji Temple. Myriad fragments of clay figures were excavated at the site of the remains of its Golden Hall (Kondō). The snail-shell curls (J. rahotsu) are those of a Buddha image in a colossal scale, a so-called jōroku image: 2.4 meters tall when seated. There are also fragments from a jōroku bodhisattva image, likely a standing figure reaching to a height of 2.8 meters, which can be identified as such as they seem to be parts of the hairstyle worn by bodhisattvas.

The Saino’o Haiji abandoned temple site is in what was Hōki Province in the western part of present-day Tottori prefecture. There was once a prominent temple in the San’in region spanning Tottori prefecture, Shimane prefecture, and the northern part of Yamaguchi prefecture. A great number of statue fragments was excavated at this site; they represent traces of statues of all kinds, ranging from small statuettes to colossal jōroku images. The fragments discovered here exemplify the spread of Buddhist culture from the capital to the periphery.
