[1] In the 1460s, a struggle for control of Echizen Province started between two deputy-governor houses, the Asakura and the Kai.

[6] The Kai allied with Togashi Kochiyo [ja], a faction leader who supported the western army, and was currently fighting for control of Kaga against his older brother in the Togashi family, Masachika, who supported the eastern army.

[7] A few days later, the Kai went to invade Echizen, and engaged Toshikage's army at Hosorogi-go on 8 August, which was on the boundary of the two provinces.

The Kai won, killing 70 of Toshikage's men and wounding 800, and then retreated back into Kaga.

Three weeks later, on 1 October, the Kai returned to the area, and burned territory close to Yoshizaki.

After they returned, the dominant warlord of Mino Province, southeast of Echizen, decided the fighting had gone on too long, and ordered Toshikage and the Kai to accept a truce.
