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. ==Government==
