What was the August 15, 1945 radio address by Emperor Hirohito commonly called?

Emperor Hirohito's August 15, 1945 radio address was commonly called the Jewel Voice Broadcast.

The Japanese name is Gyokuon-hōsō, which can be translated as “Jewel Voice Broadcast.” The title referred to the emperor's voice as a precious or jewel-like voice and reflected the traditional distance between the emperor and the general population.

Hirohito's message announced that Japan had accepted the Potsdam Declaration. He referred to the atomic bomb as a new and exceptionally destructive weapon, and he urged the Japanese people to endure the difficult future that followed the decision.

The speech was not transmitted live. It had been recorded on August 14 and replayed at noon the next day. Because of the formal language, poor audio quality, and indirect wording, some listeners were initially unsure whether the emperor had explicitly announced surrender.
