On this day, 8 October 1967 Yamazaki Hiroaki was killed by police, and around 600 people injured in Japan during an anti-war demonstration near Haneda airport. Students demonstrating against the Vietnam war had fought riot police on a bridge, forcing them back and commandeering a police van and water cannon truck. They had been driving the truck towards the airport when a cry went up that a Kyoto University student had been killed, and fighting stopped until his body was removed, and police then used tear gas, batons and water cannon to disperse protesters, sweeping some of the bridge into the river. Despite the repression, the battle marked a turning point for the radical student movement at the time which then became increasingly militant.
This is an interesting article about the Japanese student movement at this time: https://libcom.org/history/zengakuren-japans-revolutionary-students https://www.facebook.com/workingclasshistory/photos/a.296224173896073/1825265914325217/?type=3
