原爆許すまじ：1954年日本のうたごえ

This film documents a large-scale event organized by the Utagoe (Singing Voice) working class choral and musical movement that took place over the course of three days in Tokyo on November 27, 1954 at Kyoritsu Auditorium and Tokyo Metropolitan Gymnasium. Tens of thousands of people from factories and farming villages across Japan take part. Folk songs from different local regions of Japan are sung and laborer choruses perform. Choruses and songs and dances from Korea and China are heard. The finale is a mass choral performance of “The Unforgivable Atom Bomb.”
