伊勢湾
During the Kamakura period Shima came under the control of Hōjō clan, followed by the Kitabatake clan for much of the Muromachi period, although the Kuki clan, originally pirates in Ise Bay based at Toba Castle dominated much of the coastal areas by the end of the Sengoku period. Ohama Kagetaka was also a pirate operating in the Ise Bay area of Shima Province during the 16th century.
