Karatsu Castle (Maizuru Castle)

Karatsu Castle, also known as Maizuru Castle ("Dancing Crane Castle") for the shape of its outlying baileys, was built between 1602 and 1608 by Terasawa Hirotaka, a feudal lord who had served under Toyotomi Hideyoshi during the Japan invasions of Korea. Constructed at the mouth of the Matsuura River on a coastal promontory overlooking Karatsu Bay, the castle anchored the domain that administered this stretch of northern Kyushu through the Edo period, passing through several daimyo families including the Ogasawara before the abolition of the han system in 1871. The original keep was dismantled in the Meiji-era castle demolitions of the 1870s, and the stone foundations (ishigaki) and portions of the moat are what survive from the Edo-period structure. The present five-story, five-tier keep is a 1966 ferroconcrete reconstruction built on the original stone base, styled after regional keeps of the period rather than an exact replica, since no architectural plans of the original survive. Inside, the museum galleries are arranged chronologically across the reconstructed floors, covering the castle's founding, the Terasawa and successor domains, samurai armor and weaponry, and Karatsu's role in trade with the Korean peninsula, moving up to an open observation floor at the top with views over Karatsu Bay and Kagami Shrine. The keep is surrounded by Maizuru Park, planted with roughly 3,000 cherry trees, and the stone ramparts and inner moat remain the most historically authentic elements on site. As a coastal fortress built in the years immediately following the failed Korea campaigns, Karatsu Castle reflects the reorganization of Kyushu's defenses and daimyo holdings in the early Edo period.
