Karatsu Castle - History

History

Terasawa Hirotaka, a retainer of Toyotomi Hideyoshi, became lord of Karatsu in 1595. In the Battle of Sekigahara in 1600, he joined the forces of Tokugawa Ieyasu and attacked Gifu Castle. He was rewarded with greater lands around Karatsu, forming a dominion of 123,000 koku. In 1598, he abandoned his original castle of Nagoya Castle, and started work on a new castle at Karatsu, using many materials from the old one, from 1602 1608. The Tokugawa shogunate ordered neighboring tozama domains to contribute to its construction, and they did so primarily by excavating its network of moats. In 1637, in part due to his failure to suppress the Shimabara rebellion, his lands were confiscated by the Shogunate. Karatsu Domain was given over to the control of the Ōkubo clan (1649–1678), Matsudaira (Ogyū) clan (1678–1691), the Doi clan (1691–1762), Mizuno clan (1762–1817), until finally coming into the possession of the Ogasawara clan in 1762.

In June 1869, the title of daimyo was abolished, and in 1871, Karatsu Domain itself was abolished with the abolition of the han system, and became part of the new Saga Prefecture. Karatsu Castle was pulled down shortly afterwards, and in its place Maizuru Park was established in 1877.

The current donjon and some other structures of the castle were reconstructed in 1966 to boost local tourism and to function as a local museum. The current donjon features five tiers and five stories, with a lower ground floor; it also houses an exhibition area. Many of the yagura date from the same time, although the Tatsumi Yagura was added in 1990.
