 Though the two other castles in the city, Kanō Castle and Kawate Castle, only have ruins marking their former presence, they have both had important roles in the city's past.Kanō Castle was built shortly after the Battle of Sekigahara when Tokugawa Ieyasu ordered the Toyotomi family to build it upon the ruins of a former medieval castle.Okudaira Nobumasa was the first person to live in the castle and he was followed by his descendants until the Meiji period.
