水野氏
The area was under control of the Mizuno clan since the 15th century. During the Battle of Sekigahara in the Sengoku period, Mizuno Nobumoto, Mizuno Tadamori, and Mizuno Tadashige all fought under the banner of Tokugawa Ieyasu. In 1601, because of the support of the Mizuno clan, Mizuno Wakenaga, was given control of the Ogawa Domain, which produced 9,820 "koku". In 1606, Wakenaga was transferred to the nearby Shinshiro Domain, which produced 10,000 "koku". The Ogawa Domain was eventually merged with the Owari Domain
