Tamura Ujiaki served as a bushō during the Sengoku and Azuchi-Momoyama periods.
Ujiaki was born as the son of Tamura Takaaki, a sengoku daimyō and the twenty-fourth head of the Tamura clan.
Ujiaki got along well with his older brother, Tamura Kiyoaki. Kiyoaki only had one child, a daughter named Megohime, so Ujiaki was expected to be his successor. In the eighth month of 1584, Ujiaki died in battle against Ōuchi Sadatsuna.
Kiyoaki did not have any children other than Megohime so, in 1586, after his demise, a dispute arose over the succession within the Tamura family that also involved the Date and the Sōma clans. Thereafter, upon the direction of Date Masamune, Ujiaki’s son (Tamura Muneaki) became the successor.
