Takashima

The Takashima were a branch of the Sasaki family from Takashima district in western Ōmi. Their founder Takashima Takanobu built Shimizuyama Castle in 1235, and his descendants held it for generations.

The family served the Ashikaga shoguns during the Muromachi period and later came under the Rokkaku alongside other Takashima branches. Shimizuyama Castle is thought to have fallen during Oda Nobunaga's campaign in Takashima in 1572; the family declined with the fall of the Rokkaku.
