The construction of Matsue Castle began in 1607 and finished in 1611, under the local lord Horio Yoshiharu. In 1638, the fief and castle passed to the Matsudaira clan, a junior branch of the ruling Tokugawa clan. Most Japanese castles have been damaged or destroyed by war, earthquakes, or other causes. Since a large part of their construction was wooden, fire was a major hazard. Matsue castle was built after the last great war of feudal Japan, so it never saw a battle. Yet only some of the walls and the keep exist today.
