The Sunda Mizu province (Y1) was a Yasuki controlled province created after the Yasuki joined the Crab in the 4th century. The southern parts of the Wall Above the Ocean mountains stretched into this province, which bordered on Earthquake Fish Bay. The River of Gold passed through these mountains and into the Bay. It most notably contained Shiro Kano, Yasuki Defiance and Sunda Mizu Mura.
