Überblick
Founding
The exact date of Sugaya-yakata's founding is unknown, but it is traditionally said to originate as a manor built in the early Kamakura period by Hatakeyama Shigetada, a powerful vassal of the Kamakura shogunate, at Sugaya along the Toki River, a strategic point on the Kamakura Kaidō road. The 1187 entry of the Azuma Kagami chronicle records that Shigetada, accused of treason, shut himself up in "Sugaya-yakata in Musashi Province" to protest his innocence.
Succession of Lords
Shigetada distinguished himself in battles such as the Uji River fight during the Genpei War and the Ōshū campaign, earning renown as a "model of the Kamakura warrior," but was killed at Nigorikawa in Musashi Province in 1205 through a plot by the Hōjō clan. The manor is said to have subsequently passed to the line of Ashikaga Yoshizumi, though its history through the 15th century is unclear. In 1488, on the order of Yamanouchi-Uesugi Akisada, Ōta Sukeyasu rebuilt Sugaya-yakata, and it became a stronghold of the Yamanouchi-Uesugi clan. After the Night Battle of Kawagoe in 1546, the Later Hōjō clan advanced into the area, and Koizumi Kamon-no-suke served as castellan until the end of the Sengoku period.
Structure
A flatland manor facing a cliff over the Toki River, it covers roughly 130,000 square meters. The main bailey is surrounded by a second, third, and western bailey, with the natural deep valleys on its east and west serving as outer moats. Its earthworks survive in good condition, along with moats, gate approaches, and earthen bridges, making it a representative example of a medieval manor-castle in the Kantō region.
Present State
The Saitama Prefectural Ranzan History Museum now stands on the site, exhibiting materials related to Hatakeyama Shigetada and medieval manor-castles. Together with the Matsuyama, Sugiyama, and Ogura castle ruins, it is designated a National Historic Site as the "Hiki Castle and Manor Ruins Group," and in 2017 it was selected among the Continuation of Japan's Top 100 Castles (No. 120).
