Amago clan
The same year (1540), they attacked the Amago retainer Takeda Nobuzane (武田信実) who had been hiding with the Amago clan at Sato-Ginzan Castle. Nobuzane fled to Izumo Province and the Aki-Takeda clan was utterly annihilated. In addition, Motonari took over the Kawachi Keigoshu (川内警固衆), a pirate organization owned by the Aki-Takeda clan, which would become a large part of the Mori navy later.
