Fukuzen-ji, Buddhist temple in Tomo-machi, Fukuyama, Japan.

Fukuzen-ji is a Buddhist temple in Tomo-machi built on a hill called Kaiganzan Senjyuin and features a large open-sided pavilion. This structure frames views across the Seto Inland Sea toward the distant Bentenjima island, creating a natural viewing platform.

Fukuzen-ji was founded around 950 in the Heian period by the itinerant monk Kūya, and belongs to the Daikaku-ji branch of Shingon Buddhism. Its reception hall, later named Taichōrō, was built in the Genroku era. During the Edo period the temple served as the guest house for Korean diplomatic missions, twelve of which travelled to Japan, and became a meeting place for Japanese scholars of Chinese medicine and calligraphy.

The reception hall, named Taichōrō in 1748 by chief envoy Hong Gye-hee, holds a plaque whose characters were copied by his son Hong Jing-hae. Korean envoys left poems and calligraphy, and the temple keeps these documents as Fukuyama city cultural properties. The hall served as lodging for the twelve Edo-period Korean missions.

The temple sits about 30 minutes by bus from Fukuyama Station near the coast. Visitors should wear sturdy shoes and allow time for the walk up the hillside.

The flat plaque bearing the name Taichōrō was copied by Hong Jinghai, son of envoy Hong Gye-hee, and given to the monks in 1748; the characters now on display are a copy of his writing. Poems composed impromptu by the delegation also survive at the temple.
