during this conflict, under circumstances not entirely clear: he may have either been killed during the skirmish at Nomoto or when Masakado set fire to his residence. On the 21st day of the 10th month of the same year, Taira no Yoshimasa (平良正), Masakado's paternal uncle or cousin who was also related by marriage to Mamoru, seeking to avenge the deaths of Kunika and Mamoru's sons, faced Masakado in battle in the village of Kawawa (川曲村) in western Hitachi (identified with the town of Yachiyo, Ibaraki) but Masakado once again proved the victor; more than sixty of Yoshikane's men were killed while the rest dispersed. After his humiliating defeat, Yoshimasa called to Yoshikane – now the vice-governor of Kazusa Province – for aid, who then gathered a large number of warriors from Kazusa and Shimōsa such that officials from the two provinces initially attempted to prevent their dispatch (Such protests were later withdrawn after the issue was deemed to be a private matter beyond the sphere of state affairs).

Despite only having about a hundred poorly-equipped soldiers with him, Masakado inflicted heavy casualties upon his enemies' several thousand strong army. Scattered and thrown into confusion, Yoshikane and the remnants of his forces fled to the provincial headquarters of Shimotsuke, Masakado pursuing them. Although he managed to surround his uncle in the governmental offices, Masakado, seemingly concerned about subsequent censure should he kill Yoshikane then and there, allowed him to escape through a gap in his western line. He then filed a formal grievance with the provincial authorities in neighboring provinces before returning to his territory. Not long after his victory, Masakado received a summons from the imperial court because of a complaint lodged against him by Minamoto no Mamoru over the battle at Nomoto. Masakado then hurried to the capital to give an account of himself; his
