Egami Ietane served as a bushō during the Azuchi-Momoyama period.
Ietane was born as the third son of Ryūzōji Takanobu. As a condition of a settlement between the Ryūzōji and Egami clans, Ietane was adopted by Egami Taketane and then inherited the headship of the Egami clan. He was appointed by his father as the lord of Seifukuji Castle in the Kanzaki District of Hizen Province. Upon orders of his father, he participated in numerous battles including, in 1584, at the Battle of Okitanawate in which Takanobu was killed.
In 1589, after Nabeshima Naoshige moved to Saga Castle, Ietane replaced him as the lord of Hasuike Castle. At this time, Ietane received Katsushige, the lineal heir of Naoshige (which adoption was later canceled).
Ietane served in the Bunroku Campaign on the Korean Peninsula but died of illness in Busan in 1593.
Ietane was known for having a commanding presence and demonstrating exceptional military prowess. Among his siblings, it is surmised that Ietane inherited the most abilities from his father, Takanobu.
