Young unmarried women, under the age of twenty-five, were mobilized for factory labor in 1944. Since many were sent to war factories, there was fear of enemy attack. Just before the war ended in August 1945, several hundreds of young women would die in a B-29 air raid on an Army-Navy factory in Aichi Prefecture. As the Japanese photo caption reads, these women "sacrificed themselves" for Japan.
