731部隊の真実～エリート医学者と人体実験～」の英語化

Unit 731 of the Japanese Imperial Army secretly developed and tested bacteriological weapons on human subjects in Manchuria during the Sino-Japanese War. At the end of the war, evidence was destroyed, and personnel kept silent, concealing the truth for decades. However, NHK recently found more than 20 hours of audio recordings from a 1949 war-crimes tribunal.
