"砦" (pronounced "toride") refers to a type of fortification or small castle in Japan, often built on elevated ground for strategic defense. These structures were typically constructed using wood and earth, serving as lookout points and shelters during conflicts. They played a crucial role in the military strategies of feudal Japan. In addition to their military function, 砦 were also used to protect local communities and resources. They often housed soldiers and provided a safe haven for civilians during times of war. The design and location of a 砦 were influenced by the surrounding landscape, making them effective in their defensive roles.
