In 1563, the
Sōtō-shu practitioners threw in their lot and revolted in Mikawa. Joining the rebels were Yoshinobu,
Honda Masanobu,
Hachiya Sadatsugu and others whom were discontent serving Ieyasu.
Rennyo's grandson,
Kuzei, led the people into revolt since they felt their Honshōji beliefs were being robbed by Ieyasu's failed campaigns and sought to "reclaim" their origins. The reasons for the family vassals joining the rebels may stem from their desires to overtake Mikawa or due to lack of trust for Ieyasu. Confronting their former master at
Noha Castle, Yoshinobu and others fought against troops led by Ieyasu's suppression forces. Like the other rebel family vassals, Yoshinobu was captured alive in July 1563. Ieyasu forgave his crimes and was once again granted his rights as a retainer. He sought to redeem his image by helping the subjugation effort. By January 1564, the rebels were quelled but the lasting impact of their fall caused a rift with Ieyasu's supporters. Those who felt sympathy for the rebels thought they had failed to live up to the people's trust, their loyalties hurt by Ieyasu's choice to subjugate them. ==Battle of Mikatagahara==
