Le château en bref
Shizuhatayama Castle (賤機山城), also known as Rinzaiji-jō, occupies the ridge of Shizuhatayama, at Ōiwa in Aoi Ward, Shizuoka. This mountain castle (yamajiro) with successive enclosures, at an elevation of about 180 metres, served as a refuge and defensive stronghold for the Imagawa residence at Sunpu. Its date of foundation is uncertain: it is said to have been built under Imagawa Norikuni around 1334–1338, or under Imagawa Norimasa around 1411. In 1568, during Takeda Shingen's invasion of Suruga, Imagawa Ujizane fled and the Takeda occupied Sunpu, where the residence was set on fire. The castle is said to have been abandoned after Tokugawa Ieyasu entered Sunpu in 1582. It retains a main enclosure, terraces to the north and south, embankments, cut ditches and a probable tower platform. The wooded ruins can be explored on hiking trails from Shizuoka Sengen Shrine; the Shizuhatayama kofun nearby, designated in 1953, is distinct from the castle.
