Hamamatsu Castle

Hamamatsu Castle was the residence of Tokugawa Ieyasu for seventeen years, from 1570 to 1586, during a formative period of his career when he fought the Battle of Mikatagahara against Takeda Shingen and gradually expanded his territory through the Sengoku period. Because Ieyasu went on to become shogun and several later lords who served here also rose to senior positions in the Edo government, the castle became known as the shusse-jo, or castle of success, and it remains a popular subject of local pride in Hamamatsu. The current stone base is built in the nozura-zumi style, using irregular, unshaped fieldstones stacked without mortar, a construction technique typical of the Sengoku and early Edo periods and distinct from the more finished cut-stone walls seen at later castles such as Kakegawa. The wooden keep that once stood on this base was dismantled in the Meiji era, and the present three-story concrete reconstruction was completed in 1958, modeled on depictions from Edo-period records rather than an exact restoration. Inside, the reconstructed keep houses exhibits on Ieyasu's years in Hamamatsu, including armor replicas, castle models, and information on the Battle of Mikatagahara, one of the few defeats Ieyasu suffered in his career and an episode he reportedly used afterward as a lesson in caution. The surrounding Hamamatsu Castle Park preserves sections of the original stone walls and a moat, and the grounds include a statue of a young Ieyasu. The site today functions primarily as a public park and observation point, with the keep's upper floor offering views over central Hamamatsu.
