Middle Ages

The area name of Yatomi appears in Kamakura period documents, as part of ancient Owari Province.

Early modern period

During the Edo period, the area was noted for raising ornamental goldfish.

Late modern period

During the Meiji period, the area was organized into villages under Kasai District, Aichi Prefecture, with the establishment of the modern municipalities system. Kasai District later became Ama District, Aichi. Yatomi was proclaimed a town on August 26, 1903.

Contemporary history

The Isewan Typhoon of September 26, 1959, created extensive damage to the area. Efforts to merge Yatomi with the neighboring town of Kanie failed in 2004 over a dispute on the naming of the new entity.

The city of Yatomi was founded on April 1, 2006, from the merger between the former town of Yatomi, absorbing the village of Jūshiyama (both from Ama District).
