Komine Yoshina served as a bushō during the Sengoku and Azuchi-Momoyama periods.  Yoshina was the tenth head of the Komine clan.

Yoshina’s older brother, Komine Yoshichika, inherited the Komine clan but then became the head of the Shirakawa-Yūki clan so Yoshina inherited the Komine clan.  In 1575, after Yoshichika was apprehended by the Satake clan, Satake Yoshishige sought to stabilize the territory of Shirakawa by designating Yoshina as his representative of the Shirakawa-Yūki.  In 1589, when Date Masamune attacked the Nikaidō clan at Sukagawa Castle, Yoshichika had Yoshina deploy with a reinforcement army.

At the time of his death, his son, Yoshitsuna, was two years old so Yoshitsuna became the adopted heir of Yoshichika and acquired the name of Shirakawa Yoshitsuna.  The vestiges of the Komine clan were later inherited by Yoshitsuna’s son, Tomokage.
