This is a statue of Japanese cypress (J. hinoki) dyed in a red wash to resemble sandalwood. Its robes are decorated in designs of cut gold leaf (J. kirikane). The influence of art from the Song dynasty (960–1279) in China can be seen especially in its ornate hairstyle and the expression of its robes. This was the main object of worship (J. honzon) at Rengezōin, a sub-temple of Shitenōji in Osaka. Sutras and other materials were deposited within this statue at the time of its consecration.

An ink inscription at the base of the statue tells us that it was the principal icon (honzon) at the Rengezōin cloister of Shitennōji Temple in Osaka, and a colophon on one of the sutras deposited within the statue reveals its date of production and the people who had it made. The image is thought to be the work of a master Buddhist sculptor of the Zenpa workshop. This workshop made a substantial number of images for the important Saidaiji priest Eison (1201–1290), who had great influence at Shitennōji around the time of the statue’s production.

The influence of Chinese Song dynasty can be seen on a decorative hair style and a draping robe. This statue was originally the principal image of Zōkezō-in in Shitennō-ji Temple, Osaka Prefecture. The various objects including sutra were deposited in the hollow of the statue.
