Château d'Iinoya

The Iinoya Castle stands on a mountaintop with stone walls and wooden structures following traditional Japanese fortification designs of the medieval period.

Built during the Sengoku period, this military fortress served as headquarters for the Ii clan until its demolition under the Tokugawa shogunate's one-castle-per-province law.

The castle grounds contain multiple defensive positions and living quarters that reflect the strict social hierarchy of medieval Japanese military society.

Visitors can reach the castle ruins by taking a local bus from Hamamatsu Station to the base of the mountain, followed by a 30-minute walk.

The castle site provides physical evidence of medieval Japanese military engineering through its remaining stone foundations and defensive earthworks.
