Shiyozan Koufukuji Temple is a Soto Zen Buddhist temple in Ishinuki, Tamana City, Kumamoto Prefecture. Located at the eastern foot of Mount Kannondake in the Shodai mountain range, it is known for its long history, cultural treasures, and quiet natural surroundings. The temple is also the 24th temple on the Higo Saigoku Kannon Pilgrimage.
According to temple tradition, Koufukuji was founded in 1357 by Kikuchi Takasumi, who invited the Zen master Daichi to serve as its founding priest. The temple was established as a Soto Zen institution, and Kikuchi Takasumi’s wife, Ryōgo-ni, is said to have donated the temple grounds in support of her husband’s wishes.
Koufukuji became a family temple of the Kikuchi clan, which helped protect and maintain it. The temple preserves memorial tablets, old documents, and other objects associated with the clan. After the Kikuchi family’s influence declined, the temple also fell into decline, but it was later restored with support from Kato Kiyomasa.
Koufukuji was originally affiliated with Gidaiji Temple in Kaga. In 1640, it became a direct branch temple of Eiheiji, one of the principal temples of the Soto Zen school. It has continued to preserve its Buddhist traditions and historical connections ever since.
A small spring called Gozenzui stands near the temple gate. According to local tradition, Toyotomi Hideyoshi used this water when he traveled to Kyushu. Later feudal lords, including Kato Kiyomasa and members of the Hosokawa family, are also said to have used it. The spring remains a notable feature of the temple’s historical grounds.
A sign for the Shodai Eighty-Eight Kannon Pilgrimage hangs at the temple gate, welcoming worshippers and visitors. The present main hall was relocated from an earlier meditation hall. In the past, as many as 100 monks are said to have practiced there, and the sound of their chanting could be heard in the surrounding area.
The temple grounds contain a memorial tower associated with the Ishinuki vendetta in Tamana. The incident is remembered as one of Japan’s last acts of revenge of this kind. The bodies of those killed in the vendetta were temporarily buried behind the temple, and a memorial tower was later erected for their repose. The monument remains today as a reminder of this episode in local history.
Koufukuji is associated with a number of important historical documents and Buddhist works. Japan’s national Important Cultural Properties connected with the temple include Daichi’s calligraphy, “Tōkoku Myōkō Joyagē”; four documents concerning the transmission of the temple’s robes and teachings, accompanied by a twenty-five-panel Buddhist robe; and 108 documents from the temple archives. These works are held by the Kumamoto Prefectural Museum of Art.
Kumamoto Prefecture has also designated documents relating to Taiheinoji Temple and Koyama Kannondō, together with a map of Shōhōji Temple, as Important Cultural Properties. Tamana City has designated works attributed to Dōgen, including sections of the Shōbōgenzō, and a line of calligraphy attributed to Daichi as Important Tangible Cultural Properties.
Koufukuji has been served by generations of Soto Zen priests, beginning with Daichi Sokei and followed by other respected monks. The temple’s history extends through 34 generations of abbots.
Visitors interested in Buddhist history, regional culture, and historic temples can appreciate Koufukuji as a place where the legacy of the Kikuchi clan, the teachings of Soto Zen, and the surrounding mountain landscape come together.
