Images of the *Amida 阿弥陀 trinity made in the style of the Amida trinity at Zenkōji 善光寺 in Nagano Prefecture. This triad is the principal devotional image at Zenkōji and is said to have originated in India. It then traveled to China, and was brought to Japan in 602. It is a triad of Amida with the attendants *Kannon 観音 and *Seishi 勢至 rendered in gilt bronze. The main figure and the two attendants are placed against the same nimbus (see *ikkō sanzon 一光三尊). The standing Amida image is shown with the right hand raised and the left hand lowered in the position known as tōken-in 刀剣印 or tō-in 刀印, where only the forefinger and middle finger are extended. The attendant figures wear ornamental crowns and have their hands folded across their chest. In the Fujiwara and Kamakura periods, Pure Land Buddhism Jōdokyō 浄土教, spread in Japan and faith in the Amida became very widespread. A large number of imitations of the Zenkōji shiki Amida sanzon were made, initially in the Kantō 関東 and Tōhoku 東北 regions and later throughout the country. Many of these statues were made of bronze, and some were gold plated. There are also rare examples of wooden or iron statues. Although the size of the images varied, the central figure was most frequently around 30 cm in height. The Zenkōji shiki Amida sanzon in Zenkōji, Yamanashi Prefecture is the oldest signed example in Japan, bearing the date, Kenkyū 建久 7 (1196).
