ABOUT
About Komaki City
Located almost at the center of the Nobi Plain, Komaki became a city in 1955 through the merger of Komaki Town and Ajioka and Shinooka villages. It is known for Mount Komaki, where Oda Nobunaga moved his residence, and as a stage of the Battle of Komaki and Nagakute. The city office is in Horinouchi, where the current main building was completed in 2012.
