Sasaki no Nobutsuna

Sasaki no Nobutsuna (c. 1181–1242), fourth son of Sasaki no Sadatsuna, was a Kamakura gokenin and head of the Sasaki clan. In the Jōkyū War of 1221 his Uji River crossing was held up; after calling for reinforcements, he crossed with Hōjō Tokiuji and broke the court forces. He received the ancestral Sasaki estates in Ōmi, while his elder brother Hirotsuna, who sided with the retired emperor, was executed.

He served as Ōmi no kami. After his death his four sons divided Ōmi and founded the Ōhara, Takashima, Rokkaku and Kyōgoku houses.
