What was the Japanese name of Hirohito's 1945 surrender broadcast?

Hirohito's 1945 surrender broadcast was called the Gyokuon-hōsō.

The Japanese term is often translated as “Jewel Voice Broadcast,” referring to the emperor's voice. Hirohito used the broadcast to tell the Japanese public that the government had accepted the Potsdam Declaration and would end the war.

The speech was recorded in the Imperial Palace during the night of August 14, 1945. Technicians made two recordings because the first take was considered unsatisfactory. Palace officials hid the records during an attempted military coup intended to prevent the broadcast.

The broadcast aired over NHK at noon on August 15. Hirohito's formal language and the poor quality of the recording made the announcement difficult for some listeners to understand. Nevertheless, the broadcast was historically significant because it publicly communicated the emperor's decision and marked the beginning of Japan's transition from wartime mobilization to surrender.
