Kasuga Shrine, Shinto shrine in Kasuga, Fukuoka Prefecture, Japan

Kasuga Shrine is a Shinto shrine in Kasuga, Fukuoka Prefecture, whose dark gabled roof with curved eaves and gold ridge ornaments tops a plain light-brown wooden facade with lattice-paneled doors. A raised veranda with a wooden railing is reached by a broad stone stairway with a wooden handrail on the left. A stone lantern and a black lamp post stand before it at the edge of a wooded hill.

Tradition holds that the shrine began when Naka no Ōe, later Emperor Tenji, enshrined Ame no Koyane here. In 768, Fujiwara no Tamaro, then Dazaifu administrator, invited three deities from Kasuga Taisha in Yamato and founded the shrine. In 1586, Shimazu troops burned it during the Sengoku wars; Kuroda Kazunari rebuilt it in 1627, and the Kuroda lords later took it under their protection.

The shrine's name comes from Kasuga in Yamato, the home of Fujiwara no Tamaro, who in 768 invited three deities from Kasuga Taisha to join the local Ame-no-Koyane. Each year on the night of January 14, the Hadaka-oshi rite has newlyweds of the parish sing congratulatory songs while the groom is pushed and splashed with sacred water; it is a nationally designated Important Intangible Folk Cultural Property.

The shrine stands at 1-110 Kasuga, Kasuga, just north of the Kasuga Jinja Iriguchi crossing on Prefectural Route 31. From JR Onojo Station on the Kagoshima Main Line it is 1,500 m, about 18 minutes on foot; buses also stop at Kasuga Jinja-mae. The approach runs straight from the Oshioi Bridge over the Ushikubi River.

The shrine's eleven camphor trees, known together as Kasuga no Mori, were designated a prefectural natural monument on 16 January 1963. Behind the main hall, the site of Daiko-ji, a former branch temple of Shoten-ji, survives and holds a set of thirteen Buddhist figures.
