Kii Kokubun-ji, Provincial temple in Kinokawa, Japan.

Kii Kokubun-ji is a provincial temple on a square area on the north bank of the Kinokawa River in Wakayama Prefecture. The temple grounds include an archaeological park where excavated foundation remains of the original complex can be viewed.

Emperor Shōmu ordered kokubunji founded in every province in 741; Kii's temple is recorded by 756 in the Shoku Nihongi. The Kii Kuni Kinkomyoji reports it burned in 879, after which only the Main Hall and monks' quarters were rebuilt. It appears in the Engishiki, then in records again around 1300, became a Negoro-ji subsidiary, and was destroyed in Toyotomi Hideyoshi's 1585 conquest of Kii. The Main Hall was rebuilt in 1700 under Kishū Domain patronage.

The main hall houses a statue of Yakushi Nyorai, who represents the Buddha of healing in Japanese Buddhist tradition. This figure shows what spiritual role the place held for believers in the past and continues to hold today.

The temple is about a 15-minute walk from Shimo-Isaka Station on the JR West Wakayama Line. The archaeological park and the adjacent Kinokawa City Museum of History and Folklore can be visited together. The main hall stands on the foundations of the original lecture hall, so look for the low stone base beneath the building.

The pagoda's foundation is made of chlorite schist and measures 16.4 meters on each side, with all foundation stones still in their original positions. Excavations also revealed a pond and garden west of the central axis, a feature not mentioned in standard temple layout descriptions.
