Oki Islands: 1000-Year History of Imperial Exile

The Oki Islands in the Sea of Japan, designated a "distant exile" site in 722, received high-status political prisoners for over a thousand years: Ono no Takamura (838), [Emperor Go-Toba](/character/gotoba) (1221), [Emperor Go-Daigo](/character/godaigo) (1332). [Oki Shrine](/spot/oki-shrine), Kuroki Palace ruins and other historic sites preserve their memory.

The Oki Islands in the Sea of Japan were designated a “distant exile” site in 722 and received some of Japan’s most famous political prisoners for over a thousand years: Ono no Takamura (838), Emperor Go-Toba who spent 19 years on Nakanoshima until his death (1221-1239), and Emperor Go-Daigo (1332) — who escaped within a year and toppled the Kamakura shogunate. The four inhabited islands now form a UNESCO Global Geopark. Go-Toba sites concentrate on Nakanoshima (Oki Shrine, the imperial cremation tomb), while Go-Daigo sites are on Dogo (Kuroki Palace ruins).
