Kon'yō-ji, Buddhist temple in Teramoto, Itami, Japan

Kon'yō-ji is a Shingon Buddhist temple of the Kōyasan branch in Teramoto, Itami, founded by Gyōki. Its main hall, the Ruriden, houses a secret Yakushi Nyorai image attributed to Gyōki, displayed after the 1995 earthquake. The grounds also contain a Gyōki hall rebuilt in the Genroku era, a Kannon hall from the Kan'ei era, and a mountain gate moved from a site in Amagasaki.

Gyōki founded the temple in 731 as Konyō Seyin, a relief house for the poor, while building the Konyō pond. In 733 it became an imperially sponsored temple under Emperor Shōmu, with 36 sub-temples. It was burned in 1579 during the siege of Arioka Castle and later rebuilt; the 1995 earthquake damaged it, and the main hall was rebuilt in 1997.

The temple remains an active place for Buddhist practice and worship, where visitors can observe how rituals and ceremonies shape daily spiritual life. The carved wooden details and layout reflect values that have guided this community for centuries.

Visitors can explore the buildings, gardens, and interior spaces, with opportunities to observe Buddhist ceremonies on certain occasions. It is helpful to check access conditions in advance, as some areas may have restricted visiting times.

The temple bell is the fourth cast for the site; the current bronze bell dates from 1760. The temple's own bell tower was rebuilt in 1789, and the Heian-period Konjaku Monogatari includes a tale about a bell stolen from a temple called Koya-dera in Settsu.
