Nikaidō Yukiakira served as a bushō during the late Muromachi and Sengoku periods.  He was the third head of the Sukagawa-Nikaidō of Mutsu Province.

Yukiakira was born as the lineal heir of Nikaidō Yukimitsu.

In the eighth month of 1484, when Ashina Moritaka invaded the Iwase District, he intercepted their forces at Naganuma.  Initially, Yukiakira succeeded in repelling them, but, the next month, the Ashina conducted another raid and many soldiers were lost during a defeat in which the Ashina captured the Naganuma area.

Yukiakira is surmised to have died in 1497 or 1500.

He was succeeded by his lineal heir, Nikaidō Yukikage, but, in 1504, Yukikage died so his second son, Nikaidō Haruyuki, became the next head of the clan.
