It was the Buddha statue made around 1170 and it was done by yosegi-zukuri (a method of constructing a statue by assembling pieces of wood) with gyokugan (eyes made of crystal which were inserted into the head of a wooden Buddhist statue in order to produce a realistic appearance), personalizing the character of a mantra advocated by Dainichi Nyorai (Mahavairocana).
嘉応2年（1170年）頃に制作された寄木造、玉眼の仏像で、大日如来の説いた真言の一字を人格化した仏である。
