Mirumoto Kabe was the Mirumoto Daimyo at the time of the Battle of Sleeping River in 750. His brother Mirumoto Gojanuwan was his general and the hero of the battle. Gojanuwan had had the opportunity to claim the position of daimyo, but deferred to his younger brother both because of Kabe's skill as an administrator and because of his desire to remain a military commander.
