What was the name of Emperor Hirohito's 1945 radio announcement accepting Japan's surrender terms?

Emperor Hirohito's 1945 radio announcement was called the Jewel Voice Broadcast.

The Japanese name is Gyokuon-hōsō, a term that refers to the emperor's voice in elevated, symbolic language. The broadcast was transmitted on August 15, 1945, after Japan's leaders accepted the Potsdam Declaration and decided to end the war.

Hirohito's message was not delivered live. NHK technicians recorded him reading the rescript at the Imperial Palace late on August 14, and the recording was played over the radio the following day. A failed coup attempt by officers opposed to surrender threatened the recording before it reached the public.

The speech was difficult for many people to understand because it used formal court language and avoided a direct phrase equivalent to “unconditional surrender.” A radio announcer clarified afterward that the emperor's statement meant Japan was surrendering.
