大久保利通
Alarmed by growing rumors of unrest, Home Minister Ōkubo Toshimichi dispatched his henchman Iwamura Takatoshi to Saga to restore order. Iwamura only made the situation worse with his overbearing attitude. On the ship to Saga, he made an enemy of Shima Yoshitake, the former governor of Akita Prefecture, who was traveling to Saga at the request of Sanjō Sanetomi. Iwamura so outraged Shima that Shima decided to throw his lot in with Etō and his rebels.
