Kakurōkyō (革労協) is a leftist group in Japan. It was formed around 1980 and was involved with struggles related to Narita Airport. There was long-running conflict between the government of Japan and an alliance of leftist activists who were opposed to the airport for ideological reasons with local farmers who did not wish their land to be appropriated. In June 1999 Kakurōkyō split into two factions. In 2013 the group was believed to have been responsible for another attack on Yokota Air Base.
