Château de Hikuma Yamashiro

Hikuma Yamashiro is a Japanese castle site on the Mikatagahara plateau in Hamamatsu with stone walls that spread across the elevated terrain. The fortification included multiple baileys and defensive structures arranged for strategic purposes.

The Imagawa clan built the original fortress between 1504 and 1520 as a regional stronghold. It later developed into a key military position under the Tokugawa regime.

The site became known as the Success Castle because many of its commanders rose to prominence in the shogunate government. Visitors walking the grounds today can sense how this reputation shaped its importance in the regional power structure.

The site is now accessible as a public park where visitors can walk around and read educational displays. Wear comfortable shoes since the elevated terrain has some slopes and uneven sections.

Unlike typical Japanese castles, this fortress had no traditional central keep but instead featured a two-story guard tower in the inner bailey. This unusual design set it apart from other fortifications of its era.
