Location
Cause → Event → Consequence
The Japanese government decided to construct a new international airport in Sanrizuka without consulting or obtaining the consent of local farmers and residents, prompting widespread anger among the agricultural community and drawing support from leftist political groups including the Communist and Socialist parties.
The Sanrizuka Struggle was a prolonged series of civil conflicts and riots in which the Sanrizuka-Shibayama United Opposition League, farmers, residents, and leftist activists organised sustained resistance against airport construction, culminating in mass rallies of up to 17,500 participants and repeated deployments of thousands of riot police.
The struggle caused significant delays in the opening of Narita International Airport and resulted in deaths on both sides of the conflict, establishing the episode as a prominent example of organised community opposition to state-directed development in postwar Japan.
Political Outcome
Airport construction was significantly delayed; deaths occurred on both sides; the opposition movement persisted for decades without fully halting airport operations.
