A shogunal pacification force was sent to the Mount Tsukuba on 17 June 1864, consisting of 700 Mito soldiers led by Ichikawa, with 3 to 5 cannons and at least 200 firearms, as well as a Tokugawa shogunate force of 3,000 men with over 600 firearms and several cannons. As the conflict escalated, on 10 October 1864 at Nakaminato, the shogunate force of 6,700 was defeated by 2000 insurgents, and several shogunal defeats followed. The uprising resulted in 1,300 dead on the rebels' side, which suffered vicious repression, including 353 executions and approximately 100 who died in captivity.
