Takashima

The Takashima were a samurai house of Ōmi Province, descended from the Uda Genji line of the Sasaki clan. Their founder Takashima Takanobu, a younger son of Sasaki Nobutsuna, took his name from Takashima District and held Shimizuyama Castle. His son Yasunobu served the Kamakura shogunate as a gokenin.

In the Shimotsuki Disturbance of 1285 another of Takanobu's sons, Yoritsuna, fought for Taira no Yoritsuna and received the Kutsukidani valley, from which his son began the Kutsuki clan. The main line, descended from Yasunobu's heir Yasuuji, held the governorship of Etchū hereditarily and was called the Sasaki-Etchū house.

In the Muromachi period the Takashima served as the Ashikaga shōguns' direct troops and monopolised the guard posts of the twelve barriers of northern Ōmi. In the Sengoku age they came under the Rokkaku and declined when the Rokkaku were destroyed.
