The Sengoku daimyō Tsutsui Junkei started construction of the castle, and Toyotomi Hidenaga made it his residence. In the Edo period, it became the headquarters of the Kōriyama Domain. During this time it was held by members of the Mizuno, Okudaira Matsudaira, Honda, Fujii Matsudaira, and Yanagisawa clans. Today, many walls and moats are preserved in a public park in the city. The Yanagisawa Shrine stands on the grounds. The Castle was listed as one of the Continued Top 100 Japanese Castles in 2017. From Wikipedia
