A Japanese police officer named Katsuhiko Yoshimura was on patrol in the area, and was offered a cup of wine by Daho Mona as a symbolic gesture. The officer refused, saying that Daho Mona's hands were soiled with blood from the slaughtered animals. Daho Mona attempted to take hold of the officer, insisting he participate, and the officer struck him with his stick. Fighting ensued, and the officer was injured. Chief Mona Rudao attempted to apologize by presenting a flagon of wine at the officer's house, but was rejected. The simmering resentment among the Seediq in Musha was finally pushed to the limit. Incident On 27 October 1930, hundreds of Japanese converged on Musha for an athletics meet at the elementary school. Shortly before dawn, Mona Rudao led over 300 Seediq warriors in a raid of strategic police sub-stations to capture weapons and ammunition.

Consequently, Japan's army air corps in Taiwan ordered bombing runs over Musha to smoke out the rebels, dropping mustard gas bombs in violation of the Geneva Protocol in what was allegedly the first such use of chemical warfare in Asia. The uprising was swiftly quelled, with any remaining resistance suppressed by the third week of December 1930; Mona Rudao had committed suicide on November 28, but the uprising had continued under other leaders. Of the 1,200 Seediq directly involved in the uprising, 644 died, 290 of whom committed suicide to avoid dishonour. Due to internal and external criticism of their handling of the incident, Ishizuka and Hitomi Jirō, his chief civil administrator, were forced to resign in January 1931. However, Ishizuka's replacement,
