History of Kawagoe Castle and the Honmaru Palace

Kawagoe Castle Honmaru Palace

Kawagoe Castle was constructed in 1457 under the orders of Uesugi Mochitomo by the father-son duo Ota Doshin and Dokan. During the Sengoku period, it came under the control of the Hojo clan, and in the Edo period, Tokugawa Ieyasu appointed Sakai Tadakatsu as the castle lord, making it a significant historical site.

The current Honmaru Palace was rebuilt in 1848 by then-castle lord Matsudaira Naritsune. After the Meiji Restoration, many castle structures were dismantled, but parts of the Honmaru Palace survived by being repurposed as a prefectural office, public hall, and martial arts gymnasium, preserving it to this day.
