Japan's nuclear fight intensifies

        The 1960s were a time of social revolution. Student, civil rights activists and anti-war protesters rose up against governments around the world, and Japan was no exception. Hundreds of thousands took to the streets to denounce the security treaty Japan signed with the U.S. in 1960. The rallies, which turned violent at times, were the country's last significant protests -- until now. The recent anti-nuclear protests are gathering momentum, and a society once willing to accept the government line is starting to ask questions of its leaders.
