Sassa Ujitsuna (佐々氏綱)
Ujitsuna SASSA was the eighth son of Nobuzane KAJI, who was a son of Moritsuna SASAKI. He lived during the early Kamakura period.
There is a view that he established a base in Sasasho, Kazusa Province and called himself the Sassa clan. Narimasa SASSA, a busho (Japanese military commander), was his descendant.
