In the second Battle of Kà Ânodai, fought in 1564, Hà Âjà  Ujiyasu led his men to victory against Satomi Yoshihiro. Both Ujiyasu and Yoshihiro were the sons of the commanders at the first battle of Kà Ânodai, in which Hà Âjà  Ujitsuna defeated the combined forces of Satomi Yoshitaka and Ashikaga Yoshiaki (Oyumi).
Outnumbered 20,000 to 8,000, Satomi fell back when the Hà Âjà  vanguard advanced. But this was a feint, and an attempt to draw his enemy into a trap. However, Hà Âjà  Ujiyasu expected a trap of this sort, and had sent his son, Ujimasa, with a small force to attack the Satomi rear, surrounding, and later Ujiyasu defeated Yoshihiro. In the ensuing battle, Satomi Yoshihiro saw his son, Chokuro, killed by Matsuda Yasuyoshi, a Hà Âjà  retainer.
Hà Âjà  Ujiyasu celebrated his victory with a poem:
After the battle, Matsuda Yasuyoshi who had killed Yoshihiro's son, entered a life of monkhood, feeling remorse for the death of the young boy.
