The area around Tsuru has been continuously inhabited since the
Japanese Paleolithic period, and numerous artifacts from the
Jōmon period and
Kofun period have been found within its borders. The area has been part of ancient Tsuru County of
Kai Province since the
Nara period. During the
Sengoku period, the area was controlled by the
Takeda clan. During the
Edo period, all of Kai Province was
tenryō territory under direct control of the
Tokugawa shogunate. During the cadastral reform of the early
Meiji period on April 1, 1889, the village of Tani was created within Minamitsuru District, Yamanashi Prefecture. Tani was raised to town status on March 7, 1896. On April 29, 1954 Tani merged with four neighboring villages to form the city of Tsuru. ==Government==
