Honren-ji, Buddhist temple in Setouchi, Japan.

Honren-ji is a Buddhist temple in Setouchi featuring traditional wooden structures, meditation halls, and gardens arranged according to Buddhist architectural principles. The grounds are organized to balance different areas for religious practice and contemplation.

Honren-ji began as a Hokke-dō founded by Daikaku Daisōjō, head priest of Kyoto's Myōken-ji, in either 1338 or 1347; he instructed Ishihara Sado-no-kami of Ushimado's ruling family in the Lotus Sutra. The name "Ushimado-ura Hokke-dō" first appears in temple documents in 1450. The Main Hall was rebuilt in 1492, and in 1994 the grounds were designated a National Historic Site as a Joseon mission site.

Ushimado's Karako Odori, a boys' dance performed on the fourth Sunday of October, is said to derive from the Korean envoys who stayed here. The temple keeps nine scrolls of documents tied to those missions, designated Okayama Prefectural Important Cultural Properties, along with poems and plaques the delegates left behind.

The grounds are accessible during daylight hours, though some areas are reserved for meditation sessions and religious ceremonies. Visitors interested in attending these activities should contact the temple in advance to arrange participation.

The temple's guest hall, used by the Korean envoys, faces a garden attributed to Kobori Enshū; visits require a reservation. Nine scrolls of documents tied to the missions are kept here as Okayama Prefectural Important Cultural Properties.
