Ijimino Nobumune served as a bushō during the Sengoku and Azuchi-Momoyama periods.  He was the lord of Ijimino Castle in the Kanbara District of Echigo Province.

Originally, under the name of Nagasawa Kangorō, he was a servant of Nagasawa Mitsukuni, the chamberlain of Yuyama Castle in Etchū Province.  In 1569, after Mitsukuni surrendered to Uesugi Kenshin, he was engaged for services by Kenshin and adopted the name of Nagasawa Dōjosai Gifū.

Later, he was appointed as a magistrate for the town of Sanjō in the central portion of Echigo.  After the death of Kenshin in 1578, in the ensuing succession struggle known as the Otate Conflict, Nobumune obeyed Uesugi Kagekatsu.  Together with his older brother-in-law, Ijimino Harunaga (Shibata Shigeie), he captured Kaji Castle defended by Kaji Hidetsuna and Sanjō Castle defended by Kanamari Chikatsuna.  In 1580, following the sudden death of Shibata Nagaatsu, Harunaga adopted the name of Shibata Shigeie and inherited the headship of the Shibata clan.  At this time, Nobumune inherited the Ijimino clan and adopted the name of Ijimino Dōjosai Nobumune.

In 1581, when, owing to dissatisfaction with respect to his rewards, Shigeie launched a revolt against Uesugi Kagekatsu, Nobumune aligned with him.  In 1587, Fujita Nobuyoshi, a daimyō, led forces from Kagekatsu to surround Ijimino Castle.  During the siege, his chief retainer named Kawase Jidayū and an attendant from the Shibuya clan were lured by Nobuyoshi to betray Nobumune so, on 10/13, the castle fell and Nobumune was killed.
