Kontai-ji, Buddhist temple in Harayama, Wazuka, Japan

Kontai-ji is a Buddhist temple situated on Mount Jubu-san at 682 meters elevation. The grounds feature a main hall and a 13th-century pagoda nestled within the mountain landscape.

According to the Kofukuji Kanmu Sensho of 1441, En no Gyoja founded Kontai-ji in 675 under Emperor Tenmu's order, and Taicho restored it in 722. Emperor Shomu made it an imperial temple, and Gan'an of Kofukuji revived it in 807. The temple burned after Emperor Go-Daigo's 1331 visit and again in 1518; the present buildings date from the late Edo period.

The temple's name pairs kin (gold) with tai (womb), and its mountain, Jubu-san, was called the "Northern Omine" in contrast to the Omine range in Nara. The main image, a Kamakura-period wooden seated Miroku Bosatsu, is kept at Daigo-ji's treasury rather than on the mountain. A fire ceremony and tea offering are held on the first Sunday of September each year.

The main approach starts from the Harayama trailhead in Wazuka, reached by Nara Kotsu bus from JR Kamo Station, then about one hour on foot along the Tokai Nature Trail. A second climbing route comes from Ujitawara to the north. The gyōba circuit around the eastern precincts runs about 3.2 km and takes roughly two hours.

The temple grounds link to the Tokai Nature Trail, offering hiking paths from both Wazuka and Ujitawara through mountain terrain. This route connects several sacred sites along a single pathway.
