Yakushi-ji, Buddhist temple in Kōchi, Japan

Yakushi-ji is a Shingon Buzan-ha temple in the Kera district of Kōchi, with the mountain name Iwaya-san and Yakushi Nyorai as its main image. Its main hall stands on a hillside terrace; about twenty minutes' climb above it, near the summit, is the Iwaya Kannon-dō, the inner sanctuary of Zenjibu-ji, temple 32 of the Shikoku pilgrimage. Its main image is an Eleven-faced Kannon. Above that, a path passes a Ishizuchi Shrine hall and reaches the triangulation point on Hatchibuse peak at 212 m.

Yakushi-ji traces its origin to Minamoto no Koreyoshi, a brother of Minamoto no Yoritomo who was defeated in the Heiji War and exiled to Kera-no-shō in Tosa Province. Accused of rebellion by the Taira and killed, he was mourned by his teacher, the monk Rinyū, who founded the temple and enshrined Koreyoshi's personal image of Yakushi Nyorai. A great festival is held here every year on 11 February.

Yakushi-ji is the 59th stop on the Shikoku Mandala pilgrimage circuit, and its groundsong (goeika) asks the temple's Yakushi Nyorai to grant the lapis-lazuli medicine that heals the sickness of each year. A great festival is held here every 11 February. Above the main hall, about 20 minutes' climb leads to the Iwaya Kannon hall, the inner sanctuary of Zenjibu-ji, temple 32 of the 88-site Shikoku pilgrimage.

The main hall stands at the foot of the hill; from there a climb of about 20 minutes leads to the Iwaya Kannon Hall near the summit, and the path continues past a hall of Ishitachi Shrine to the triangulation point on Hatchibuse peak at 212 m. The temple lies in Kera, Kōchi, and the grounds are steep in places. The main festival is held on 11 February.

Above the main hall, a roughly 20-minute climb leads to the Iwaya Kannon Hall, the okunoin of Chikurin-ji, temple 32 of the Shikoku 88-temple pilgrimage. It enshrines an Eleven-Faced Kannon. Continuing past a small Ishizuchi Shrine building brings you to the triangulation point on Hachibuse peak, 212 m above sea level.
