The growing struggle for Palestinian self-determination between 1960 and 1980 was supported by radical left-wing movements worldwide, also in Japan. This is illustrated by a collection of 16mm films by militant filmmakers from various countries, which were dubbed and screened in Japan. Their Japanese audiences felt oppressed by the US after World War II, and not only sympathized but also identified with the Palestinians.
Sorry, but for now we weren't able to find movies like R 21 AKA Restoring Solidarity.
