Tamanawa Castle, Japanese castle ruins in Kamakura, Japan.
The fortification spans across multiple levels with external moats connected to the Kabaeo River, enabling naval operations from its strategic position.
Built in 1512 by Ise Moritoki, also known as Hojo Soun, the castle served as a crucial base for controlling the Sagami region until 1619.
The Ryuhouji Temple near the castle grounds contains a memorial stone for the Tamanawa Hojo clan and maintains a historical museum.
The main enclosure area sits within school property, requiring advance permission for visits during weekdays when the educational institution operates.
The castle maintained an undefeated status for 80 years until its peaceful surrender to Tokugawa Ieyasu during the 1590 siege of Odawara.
