Iwakura City, in the northwest of the Owari region, is the smallest city in the prefecture by area. In the Warring States period, Iwakura Castle of the Oda Isenokami family, which ruled the upper four districts of Owari, was here. The cherry trees along the Gojo River are famous, and "nonbori-arai," the traditional rinsing of carp streamers in the river, is a sign of spring.
