It is believed that Toyoda Castle (Toyoda-jo) was built by a military commander who governed this region around the middle of the 14th century. Standing on the banks of the Kokai-gawa, the castle had no donjon when it was originally built. It had a thatched roof and was probably used as a fortress that utilized the river water. The five-storied donjon that now stands was built in recent years. It houses an exhibition room, which features the exhibitions of the culture and industries of this region.
