Inazawa, city, northwestern Aichi ken (prefecture), central Honshu, Japan. It lies in the Owari plain, with the Kiso River on its western border.
Inazawa was a small rural town during the Edo (Tokugawa) period (1603–1867), producing vegetables for the market of nearby Nagoya (southeast). Increased urbanization in the area since World War II, however, sparked Inazawa’s growth as a residential and industrial suburb of Nagoya. Textiles and machinery are produced. Pop. (2005) 136,965; (2010) 136,442.
