During the Sengoku period, the Battle of Mimasetoge between the forces of Takeda Shingen and the later Hōjō clan occurred on what is now Aikawa Town. During the Edo period, the area was tenryō territory under direct control of the Tokugawa shogunate. After the Meiji Restoration, Aikawa village was founded on April 4, 1889 with the establishment of the modern municipalities system. It was elevated to town status on April 1, 1940. The Imperial Japanese Army established the Sagami Airfield in Aikawa, which was also adjacent to military factories in Sagamihara, an officer's training school in Zama, and numerous Army and Imperial Japanese Navy facilities in Atsugi and Yokohama. On January 15, 1955, Aikawa merged with neighboring Takamine Village and on September 30, 1956, with neighboring Nakatsu Village. In 1966, an industrial park was built on the site of the former airfield and military facilities.
