In Gyeongsang 6 (1601), Honda Tadakatsu, who was one of the Tokugawa Shitenno and became the first Kuwana feudal lord, along with the castle town of Wari, carried out the extended maintenance of the castle. Kuwana Castle was once credited as "Ogijō" and "Kaido no Meijō", but it was broken after the Meiji Restoration because it came to the shogunate in the wake of the Boshin War. The site of the castle was maintained as a Kukhua Park in 1928, and has beautiful cherry blossoms and azaleas, and is a familiar place for citizens to relax. Also in the park is the Zhenkokumori Shrine, which enshrines Matsudaira Sadozuna (koku) and Matsudaira Sadanobu (Raku-gō), and in the vicinity is the restored Banryū-ryū (a two-tiered tower with the roof tiles of the dragon, the guardian deity of the voyage. Utagawa Hiroshige) is also depicted in the "Tōkaidō Fifty-three-year Kuwana". Pets are not allowed to be free-range and use their manners.
