In the mid-1970s, protests were waning across Japan after the Red Army scandal of Asama Cottage. In Sanrizuka, people were weary of the violence and the airport was well under construction. As for Ogawa Productions, they invited criticism by pulling out and moving to a quiet village in northern Japan. But when protesters back in Sanrizuka erected a tall tower at the end of one runway, they sent a crew to document what happened. This became the final film of the Sanrizuka Series.
