Kamo
Kamo lies in the hills and valleys of inland Mikawa, around the town of Koromo. During the warring states era local families including the Matsudaira, Suzuki and Miyake competed for influence here. Koromo became the seat of a small domain in 1604. Later its Naitō lords built a new castle on higher ground after repeated floods threatened their earlier site; the work begun in 1780 gave the town the stronghold known as Shichishū Castle.
