Unnō

The Unno were a warrior house at Unno manor in Shinano, claiming descent from the Shigeno clan. With the Nezu and Mochizuki they were known as the three Shigeno families, and styled themselves the Shigeno main line. Unno Yukichika and his son served Minamoto no Yoshinaka and fell in battle; his surviving third son Yukiuji served Minamoto no Yoritomo and ranked among the four great bowmen of the Kanto.

In 1335 Unno Yukiyasu joined Hojo Tokiyuki's attempt to retake Kamakura. The clan sided with the Southern Court, and Yukiyasu was killed in 1352 at Kotesashigahara alongside Prince Munenaga.

Rivalry with the Murakami turned against the Unno: Mochiyuki fell in 1467 and the family lost the Shioda estates. In 1541 a coalition overwhelmed them at Unno-daira; the clan head fled and the main line ended. Sanada Yukitaka, who had married into the family, claimed its succession.
