Zenkō-ji 善光寺

Zenkō-ji (善光寺, Temple of the Benevolent Light) is a Buddhist temple located in the city of Nagano, Japan. The temple was built in the 7th century. It is one of the few remaining pilgrimage sites in Japan. The modern city of Nagano began as a town built around the temple.

Zenkō-ji was founded before Buddhism in Japan split into several different sects. It currently belongs to both the Tendai and Jōdoshū schools of Mahayana Buddhism, and is co-managed by twenty-five priests from the former school, and fourteen from the latter. The temple enshrines images of the Amida Buddha. According to legend, the image, having caused dispute between two clans, was dumped into a canal. It was later rescued by Honda Yoshimitsu. The temple was thus named "Zenkō," according to the Chinese transliteration of Yoshimitsu's name.

The main Buddhist image is a hibutsu (secret Buddha), a hidden Buddha statue, not shown to the public. This hibutsu is rumored to be the first Buddha statue to ever be brought to Japan. The commandments of the temple require the absolute secrecy of the statue, prohibiting it to be shown to anyone, including the chief priest of the temple. However, a replica of the statue (Maedachi Honzon) has been created which can be shown publicly once every six years in spring, in a ceremony called Gokaichō. This event attracts many worshippers and visitors.
