Futamata Castle was located in Futamata-cho, Hamamatsu City, Shizuoka Pref. The founder of the castle is unknown, but as early as in 1520, it was resided by Futamata Masanaga, a retainer of the Imagawa clan. In 1568, Tokugawa Ieyasu captured the castle as a part of his campaign to capture Totomi province. Since then fierce battles to claim the rights to this castle were fought between Ieyasu and Takeda Shingen. In 1579, Ieyasu’s wife, Tsukiyamadono, and his eldest son, Nobuyasu, were accused of conspiring with the Takeda clan. Ieyasu’s wife was executed and Nobuyasu was forced to commit seppuku (cutting the belly) at this castle. In 1590, Horio Munemitsu was assigned as the castellan by Hideyoshi, but he was transferred to another domain in 1600 and the castle was dismantled. At the present time the castle ruin is arranged into a beautiful park, where nothing other than the stone walls remains. With Nobuyori’s graveyard nearby, Futamata Castle is a castle of tragedy.
