洞泉寺, Buddhist temple in Iwakuni, Japan

Dosenji Temple is a Buddhist temple in Iwakuni situated near the base of Mount Shiroyama and features traditional Japanese architecture with wooden structures and tiled roofs. The complex comprises several buildings arranged in a harmonious layout around a central prayer hall.

The temple traces its origin to 1450, when Kikkawa Tsunenobu, a local lord of Aki Province, founded Bandokuzan Dosenji at Shinjo-Oasa in his territory. In 1603, following the Kikkawa clan's move from Aki to Suo Province after the 1600 Battle of Sekigahara, the temple was relocated to its present site and given its current name, written with the characters for "cave" and "spring".

The temple grounds hold the Kikkawa family cemetery, burial place of the Iwakuni domain lords, with 51 graves divided between two hillside sites, Otō on the mountain and Otō in the temple valley. Beside Kikkawa Tsunemoto's grave stands the "Whose Sleeves" water basin, attributed to Kobori Masakazu (Enshū) and named for its resemblance to a kimono sleeve.

Visitors should prepare to remove their shoes before entering interior spaces, as this is standard practice in Japanese temples. The best time to visit is after sunrise when sunlight gently illuminates the wooden structures and fewer people are present.

The temple grounds hold the Kikkawa family cemetery, the graves of the Iwakuni domain lords, designated a Yamaguchi Prefecture historic site in 1988. Beside the grave of Kikkawa Tsunemoto stands a stone water basin called the "Whose Sleeves" basin, said to be the work of Kobori Masakazu (Enshu) and named for its resemblance to a kimono sleeve.
