​In early 1968, Ogawa and his colleagues founded Ogawa production. Afterward they went forward to Sanrizuka in Narita City, Chiba. There, the farmers protested against the construction of the new airport. Ogawa spends time with the farmers, the students and youth organizations all around the country creating his movie Summer in Narita. After 8 years of shooting, he makes six more projects perfecting his long series the Sanrizuka 7. As if writing a long novel, it was his idea to follow the repeated four seasons of the farmers, to capture the change and establishment of their philosophy. He establishes a method of documenting events through the eyes of the subjects while seeking unity through active participation, which he already tried in The Oppressed Students. Ogawa Shinsuke’s documentary, which has become a means of resistance itself not only captures the voices of the oppressed but also restoring the power of perspectives to the necessary. ​
