Kira Sadatsune

Kira Sadatsune (fl. 1335–1367) was a warrior of the Tōjō Kira branch in Mikawa and younger brother of the Ōshū kanrei Kira Sadaie. When his brother marched east in 1336, Sadatsune stayed to hold Kira Manor and is the likely commander who defeated Nitta's Southern Court army there.

During the Kannō Disturbance he alone of the Kira backed Takauji and Kō no Moronao. From 1352 he fought in Mutsu, helping retake Taga Castle and storm Utsumine. After 1367 he vanishes from the records amid a feud within the clan.
