Totomi during the construction of Hamamatsu Castle

Western Shizuoka Prefecture, including the Hamamatsu area, was considered to be a crucial location for the military, and many castles were built in the flatlands and mountainous areas of the region during the Sengoku Period (1467 – 1615). When Tokugawa Ieyasu built Hamamatsu Castle, local feudal lords held power and ruled over various regions of Totomi. Some of the local lords followed Ieyasu in his conquest of Totomi, while others resisted him. When the Takeda clan invaded Totomi, some local lords joined them instead.
