Nichirin-ji, Tendai Buddhist temple in Daigo, Japan.

Nichirin-ji is a Tendai temple on the 8th station of Mount Yamizo, near the 1,021.8 m summit. Apart from the abbot's and monks' quarters, the grounds consist of a single building, the Kannon Hall (Kannon-dō), which enshrines an eleven-faced Kannon.

According to temple tradition, En no Gyōja founded Nichirin-ji in 673, during Emperor Tenmu's reign; it later fell into ruin and was revived in 807 by Kūkai, who installed an eleven-faced Kannon he is said to have carved himself. By 989 it was a Kannon pilgrimage site, and from the Kamakura period it held the 21st of the 33 Bandō stations. The hall burned in 1643, was rebuilt in 1660, and a 1880 forest fire destroyed all but the main image.

Nichirin-ji is the 21st stop on the Bandō Sanjūsankannon pilgrimage, and its honzon is an eleven-faced Kannon said to have been carved by Kūkai. Pilgrims chant the goeika: "Lost as I am, I have now climbed to Yamizo; the Buddha's light makes the mountain shine too." The temple's location near the eighth station of Mount Yamizo made it the hardest stage of the circuit; before a forest road reached the summit, some pilgrims worshipped from the foot of the mountain instead.

The temple stands near the eighth station of Mount Yamizo, Japan's highest peak in Ibaraki Prefecture, reached by taxi in about 40 minutes from Hitachi-Daigo Station on the Suigun Line. By public transport, take the Ibaraki Kotsu bus to Jake and walk about two hours from the stop. Viewing hours are 8:00–16:30 in summer and 9:00–16:00 in winter; the mountain closes in January and February for snow, though temple seals remain available.

The temple stands near the eighth station of Mount Yamizo, Ibaraki Prefecture's highest peak at 1021.8 m, which made it the hardest stop on the Bandō 33 Kannon pilgrimage. Before a forest road reached the summit, pilgrims unable to climb worshipped from the foot of the mountain instead.
