Suetsugu
The Suetsugu were local lords descended from the Sasaki of Izumo Province. Suetsugu Tanekiyo took his name from his lands at Suetsugu, where the family held a castle on Kamedayama.
Suetsugu Tadasada fought the Mōri under the Amago at Yoshida-Kōriyama in 1540. His descendant Sadataka died fighting for the restoration of the Amago in 1570, and the Mōri took Suetsugu Castle in 1571; Matsue Castle was later built on the site.
