Minakuchi Castle Ruins (Minakuchi Castle Museum)

Minakuchi Castle (sometimes called "Hekisui Castle") was founded by Kobori Enshu to provide accommodations for when Tokugawa Iemitsu was making his tour to the capital.
The Minakuchi Castle Museum, which resembles a square-shaped turret, showcases castle models and other materials related to the former Minakuchi feudal domain.
