Izumo Province
In 1600, Yoshiharu took part in Ieyasu's force. He killed Kaganoi Shigemochi, who killed Mizuno Tadashige on August 27 at Chiryu, Mikawa Province, but was injured by Shigemochi. Because of that, he could not take part in the Battle of Sekigahara on October 21. However, Ieyasu gave him 240,000 koku at Toda, Izumo Province after the battle, because Yoshiharu had killed Shigemochi and Tadauji had substituted the performance of exploits at the battle on his behalf.
