The incident began when five armed members of the United Red Army (URA), following a bloody purge that left fourteen members of the group plus one bystander dead, broke into a holiday lodge below Mount Asama, taking the wife of the lodge-keeper as a hostage. A standoff between Japanese police and the URA radicals took place, lasting ten days. The lodge was a natural fortress, solidly constructed of thick concrete on a steep hillside with only one entrance, which, along with their guns, enabled the hostage-takers to keep police at a distance.
On February 28, the police stormed the lodge. Two police officers were killed in the assault, the hostage was rescued and the URA radicals were taken into custody. The incident contributed to a decline in popularity of leftist movements in Japan.
