Kōshū Kaidō
The area around present-day Nirasaki was the ancestral homeland of the Takeda clan, which dominated Kai Province in the Sengoku period. During the Edo period, the area was "tenryō" territory under the direct administration of the Tokugawa shogunate, and the village of Niirasaki was a post town on the Kōshū Kaidō highway. During the early Meiji period, the area was organized into 14 villages under Kitakoma District, Yamanashi. Nirasaki was elevated to town status on September 20, 1892. Modern Nirasaki City was founded by merger of Nirasaki with ten surrounding villages on October 10, 1954.
