Demographics Per Japanese census data, the population of Inagi has increased steadily since the 1950s. History The area of Inagi has been settled since the Japanese Paleolithic, or for over 20,000 years, based on projectile points, stone tools and microliths found in several locations within city borders. There is evidence of several Jomon period settlements, but settlement disappeared towards the end of the Jomon period due to climate change and eruptions of Mount Fuji. The area was sparely settled in the Yayoi period, with increasing settlement density in the Kofun period. A number of Nara period remains have been found, including the ruins of a roof tile kiln. During the Heian period, the area became part of a shōen controlled by the Oyamada clan, and later by their cadet branch, the Inabe clan into the Kamakura period, and was an area contested between competing branches of the Ashikaga clan and Uesugi clan in the Muromachi and Sengoku periods. After the start of the Edo period, the area was tenryō controlled directly by the Tokugawa shogunate. Inagi as a municipality was founded on April 1, 1889 as a village in what was then Minamitama District, Kanagawa Prefecture, from the merger of 6 pre-Meiji period hamlets with the establishment of the modern municipalities system. The district was transferred to the administrative control of Tokyo Metropolis on April 1, 1893. On April 1, 1957, Inagi Village was promoted to town status, and to city status on November 1, 1971.
