Oki-jinja, Shinto shrine in Ama, Shimane, Japan

Oki-jinja is a Shinto shrine in Ama, Shimane Prefecture, on Nakanoshima in the Oki Islands. Its main hall, built for the shrine's founding in 1939, is in the Oki-zukuri style with a copper-sheet roof. The grounds cover 15,000 tsubo and include a worship hall, a prayer hall, an offering hall and a treasure house, with a cherry-tree-lined approach.

The shrine was built in 1939 to honor Emperor Go-Toba, who was Japan's 82nd emperor in the 12th century. This memorial was erected many years after his death to preserve his legacy on the islands, where he had been exiled.

The shrine's deity is Emperor Go-Toba, exiled to Oki in 1221, whose cremation mound lies next to the grounds. Two annual festivals, on 14 April and 14 October, are held here. The approach is lined with cherry trees that draw flower-viewing visitors each spring, and the neighbouring Ama Town Go-Toba-in Museum displays items connected with the emperor.

The shrine stands next to the Go-Toba funeral mound, and the Ama Town Go-Toba-in Museum is just outside the gate. From Hishiura Port, take the Oki Ama Kotsu bus bound for Akeya Beach and get off at Oki-jinja-mae, or drive about 15 minutes via Shimane Prefectural Route 317.

The shrine was completed in 1939, the year of the Go-Toba Tenno 700th Memorial marking seven centuries since the emperor's death in 1239. It was built as part of Shimane Prefecture's projects for the 2600th anniversary of the legendary founding of Japan in 1940, and was ranked a prefectural shrine (kensha) in 1943.
