This Tendai Buddhist temple is nestled in the quiet mountains. It is said to have been founded by En no Ascetic and then rebuilt by Prince Kaisei in the 8th century. During the Sengoku period, Matsunaga Hisahide donated his estate, and Miyoshi Nagayoshi, Takayama Tomoteru, and Ukon and his son issued letters of assurance of the temple's land. During the Edo period, the temple was revered by the Nagai clan, lords of Takatsuki Castle, and the Imperial family, and in the Hoei era (early 18th century), Keishoin, the mother of the 5th Shogun Tsunayoshi, carried out extensive renovations. The temple grounds include the founder's hall and Prince Kaisei's one-stone, one-character sutra pagoda. The standing statue of Shokannon in the main hall (currently on loan to the Nara National Museum) and the standing statue of Bishamonten are designated as Important Cultural Properties of Japan, the Hokyoin Tower on the mountainside to the east of the main hall is a tangible cultural property of the prefecture, and the Honzan-ji documents, including letters from Takayama Ukon, a known Christian daimyo, are designated as tangible cultural properties of Takatsuki City.
