This statue of a bodhisattva comes from Mount Haku (Kaga Hakusan) in Ishikawa. The sense of the statue’s strength achieved in the naturalistic rendering of the upper half of its body; the rounded expression of the folds in the robes; and the statue’s lower half offering a balanced, grounded impression all evoke Nara-period sculpture in dry lacquer and modeled clay.

This statue of a bodhisattva (bosatsu) is said to have been excavated at Hakusan in Ishikawa prefecture. The entire work, from the top of the head to the pedestal, including the scarf-like tenne, which hangs free falling away from the body, was produced in a single cast. The hole at the top of the head indicates the location of an iron rod that once secured this work to a mold. Although the face is abraded, the undulations of the flesh and the expression of the texture of the robe are precise, and much of the original gilding remains.

The round, high topknot and the well-balanced proportion of the body with slightly twisted waist are impressive. Reportedly, this gilt bronze statue was excavated from Mt. Hakusan in Kaga area. Having been buried in the ground for a long time, the surface has considerably corroded and the facial features are no longer clearly visible. However, gold from the gilded surface is still extant in some regions, including the back of the body. The modeling of the body is very beautiful: Ample and precise ups and downs of the body-line can be observed from breast to thigh on the front side and from the shoulders to the spine on the back side. Such modeling of the body is common to many of the Bosatsu (Bodhisattva) statues made between the late 8th and early 9th centuries, including the statue of the eleven-headed Kannon (Ekādaśamukha) in Shōrin-ji temple in Nara. This statue of Bosatsu is considered to have been made during that period. It is a valuable statue of high quality and one of a few extant examples of gilt-bronze statues made during the late 8th and early 9th centuries.
