Siege of Ōtsu

The siege of Ōtsu (大津城の戦い) took place in 1600, occurring concurrently with the battle of Sekigahara. Kyōgoku Takatsugu held Ōtsu castle for the Tokugawa, and commanded the garrison. Mōri Motoyasu and Tachibana Muneshige laid siege. The sides negotiated and Takatsugu surrendered. However, in the meantime Tokugawa Ieyasu had won the battle of Sekigahara, assuring his control of all Japan, and so the loss of Ōtsu was ultimately insignificant.

Some records of the time indicate that the local inhabitants brought picnic boxes and gathered at Mii-dera on Mount Hiei to observe the battle.
