Taisan-ji, Buddhist temple in Kobe, Japan

Taisan-ji is a Buddhist temple in Kobe that features a main hall with copper-covered roofs and traditional sliding lattice doors. The grounds extend across wooded slopes and include several buildings as well as an ancient forest along a river.

According to the temple's 973 origin narrative, it was founded in 716 by Fujiwara no Umakai, grandson of Kamatari, as a temple vowed by Empress Genshō. Umakai had a dream of Yakushi Nyorai while at a hot spring in Akashi, then built the seven-hall complex. The founding monk was Umakai's uncle, the Tang envoy Dōe. The original buildings burned in 1285, and the current Main Hall dates from around 1293–1300.

Taisan-ji belongs to the Tendai sect, not Zen, and its mountain name Sanshinzan precedes the temple name. The main hall holds both the principal image, a Yakushi Nyorai, and an Eleven-Faced Kannon that is the 25th station of the New Saigoku Thirty-Three Kannon pilgrimage. Annual rites include the Shushō-e from 1 to 7 January, the Tsuina ceremony on 7 January, the flower festival on 8 May and the Neri-kuyō procession on 12 May.

The temple is a 25-minute walk from Gakuen-Toshi Station on the Kobe Municipal Subway Seishin-Yamate Line, or is reached directly by Shinki Bus route 14 between Akashi Station and Myodani Station. Admission is 300 yen, free on New Year's Day, and grounds are open 8:30 to 17:00, closing at 16:30 from December to February.

The cliff-carved Fudō Myōō, about 2 metres tall and cut in high relief into the rock upstream on the Taisan-ji River (Ikawa), dates from the Kōan era (1278–1288) and is a city-designated historic site. The temple's 10.95 hectares of primeval forest are a prefectural natural monument, and the wider 55.9-hectare scenic area is listed among the Hyōgo 100 Forests.
