Kakegawa Castle

Kakegawa Castle is a hirayama-style Japanese castle located on a small hill in the center of Kakegawa, Shizuoka Prefecture, Japan. Originally constructed between 1469 and 1487 by Asahina Yasuhiro, a retainer of the Imagawa clan, the fortress served as a strategic stronghold for controlling the eastern half of Tōtōmi Province. Its position was particularly vital due to Kakegawa's role as an important post station on the Tōkaidō highway, which connected Kyoto with eastern Japan. Throughout the Sengoku period, the site witnessed significant military conflict, including a five-month siege before surrendering to Tokugawa forces in 1568, and later served as the seat for various fudai daimyō clans ruling the Kakegawa Domain.

The castle underwent a major transformation in 1590 under Yamauchi Kazutoyo, who completely rebuilt the complex according to contemporary designs following his acquisition of the domain. Although the original keep was destroyed by an earthquake in 1604 and reconstructed in 1621, subsequent seismic activity during the Ansei Tōkai earthquake of 1854 caused extensive damage. While many structures were repaired by 1861 and utilized as government offices after the Meiji Restoration, the main keep was not rebuilt at that time, leaving the site in ruins for much of the modern era.

Today, Kakegawa Castle stands as a reconstructed historical landmark open to the public. Following decades of ruin during the Shōwa period, a faithful reconstruction of the tenshu (main keep) and other buildings was completed in 1994. The site now features the restored Ni-no-Maru Goten palace and preserves much of the stone walls and moats dating back to the Yamauchi renovation. It serves as a cultural testament to the region's feudal history, offering visitors insight into the architectural evolution and political significance of this former provincial center.
