What was the 1945 Japanese surrender radio address commonly called?

The 1945 Japanese surrender radio address was commonly called the Jewel Voice Broadcast. The English name refers to the emperor's voice and derives from the Japanese term Gyokuon-hōsō.

Emperor Hirohito delivered the recorded message to the Japanese public at noon on August 15, 1945. It announced that Japan had accepted the joint Allied declaration demanding surrender, although the word “surrender” was not stated in the most direct modern phrasing.

The broadcast was historically significant because it was the first known occasion on which ordinary Japanese subjects heard the voice of their emperor. Hirohito used highly formal Classical Japanese, which many listeners found difficult to follow.

The recording was made twice at the Imperial Palace on August 14. The second version became the official recording and was carried by NHK across Japan the next day.
