Jewel Voice Broadcast

The Jewel Voice Broadcast (玉音放送) was the radio broadcast in which Japanese Emperor Hirohito (Emperor Shōwa 昭和天皇 Shōwa-tennō) read out the Imperial Rescript on the Termination of the War (大東亜戦争終結ノ詔書), announcing to the Japanese people that the Japanese Government had accepted the Potsdam Declaration demanding the unconditional surrender of the Japanese military at the end of World War II. This speech was broadcast at noon Japan Standard Time on August 15, 1945.

The speech was probably the first time that an Emperor of Japan had spoken (albeit via a phonograph record) to the common people. It was delivered in the formal, Classical Japanese that few ordinary people could easily understand. It made no direct reference to a surrender of Japan, instead stating that the government had been instructed to accept the terms of the Potsdam Declaration fully. This created confusion in the minds of many listeners who were not sure whether Japan had surrendered. The poor audio quality of the radio broadcast, as well as the formal courtly language in which the speech was composed, worsened the confusion. A digitally remastered version of the broadcast was released on 30 June 2015.

Broadcast
The speech was not broadcast directly, but was replayed from a phonograph recording made in the Tokyo Imperial Palace on either August 13 or 14, 1945. Many elements of the Imperial Japanese Army were extremely opposed to the idea that Hirohito was going to end the war, as they believed that this was dishonourable. Consequently, as many as one thousand officers and soldiers raided the Imperial palace on the evening of August 14 to destroy the recording. The rebels were confused by the layout of the Imperial palace and were unable to find the recording, which had been hidden in a pile of documents. The recording was successfully smuggled out of the palace in a laundry basket of women's underwear and broadcast the following day, although another attempt was made to stop it from being played at the radio station.

To ease the anticipated confusion, at the conclusion of the speech a radio announcer clarified that the Emperor's message did mean that Japan was surrendering. According to French journalist Robert Guillain, who was living in Tokyo at the time, upon the announcement's conclusion, most Japanese retreated into their homes or places of business for several hours to quietly absorb and contemplate the significance of the announcement.

After the recording was played, the record used for playing it disappeared in the post-surrender chaos, but a radio technician had secretly made a copy, which was given to Occupation authorities and is the source of all recordings available today. The original record was later recovered but has never again been played.

Content
The rescript was translated into English and was broadcast to overseas Allies by  at the same time. In the U.S., the Federal Communications Commission (FCC) recorded the broadcast, and its entire text appeared in The New York Times.

The main subject of the speech was to announce the surrender of Japan, that Hirohito "ordered our government to communicate to the governments of the United States, Great Britain, Republic of China and the Soviet Union that our empire accepts the provisions of their joint declaration."

In the speech, Hirohito noted that the war arose out of "our sincere desire to ensure Japan's self-preservation and the stabilization of East Asia […]", but "the war situation has developed not necessarily to Japan's advantage". He then stated, "moreover, the enemy has begun to employ a new and most cruel bomb, the power of which to do damage is, indeed, incalculable, taking the toll of many innocent lives", referring to the atomic bombings of Hiroshima and Nagasaki that occurred days before. He, however, did not mention the Soviet invasion of Manchuria and other Japanese-held territories that had also begun a few days before. He also said, "it is according to the dictates of time and fate that we have resolved to pave the way for a grand peace for all the generations to come by enduring the unendurable and suffering what is insufferable."

"TO OUR GOOD AND LOYAL SUBJECTS:

After pondering deeply the general trends of the world and the actual conditions obtaining in our empire today, We have decided to effect a settlement of the present situation by resorting to an extraordinary measure.

We have ordered our government to communicate to the governments of the United States, Great Britain, China and the Soviet Union that our empire accepts the provisions of their joint declaration.

To strive for the common prosperity and happiness of all nations as well as the security and well-being of our subjects is the solemn obligation which has been handed down by our imperial ancestors and which lies close to our heart.

Indeed, we declared war on America and Britain out of our sincere desire to ensure Japan's self-preservation and the stabilization of East Asia, it being far from our thought either to infringe upon the sovereignty of other nations or to embark upon territorial aggrandizement.

But now the war has lasted for nearly four years. Despite the best that has been done by everyone – the gallant fighting of the military and naval forces, the diligence and assiduity of our servants of the state, and the devoted service of our one hundred million people – the war situation has developed not necessarily to Japan's advantage, while the general trends of the world have all turned against her interest.

Moreover, the enemy has begun to employ a new and most cruel bomb, the power of which to do damage is, indeed, incalculable, taking the toll of many innocent lives. Should we continue to fight, not only would it result in an ultimate collapse and obliteration of the Japanese nation, but also it would lead to the total extinction of human civilization.

Such being the case, how are we to save the millions of our subjects, or to atone ourselves before the hallowed spirits of our imperial ancestors? This is the reason why we have ordered the acceptance of the provisions of the joint declaration of the powers.

We cannot but express the deepest sense of regret to our allied nations of East Asia, who have consistently cooperated with the Empire towards the emancipation of East Asia.

The thought of those officers and men as well as others who have fallen in the fields of battle, those who died at their posts of duty, or those who met with untimely death and all their bereaved families, pains our heart night and day.

The welfare of the wounded and the war-sufferers, and of those who have lost their homes and livelihood, are the objects of our profound solicitude.

The hardships and sufferings to which our nation is to be subjected hereafter will be certainly great. We are keenly aware of the inmost feelings of all of you, our subjects. However, it is according to the dictates of time and fate that We have resolved to pave the way for a grand peace for all the generations to come by enduring the unendurable and suffering what is unsufferable.

Having been able to safeguard and maintain the Kokutai, We are always with you, our good and loyal subjects, relying upon your sincerity and integrity.

Beware most strictly of any outbursts of emotion which may engender needless complications, or any fraternal contention and strife which may create confusion, lead you astray and cause you to lose the confidence of the world.

Let the entire nation continue as one family from generation to generation, ever firm in its faith in the imperishability of its sacred land, and mindful of its heavy burden of responsibility, and of the long road before it.

Unite your total strength, to be devoted to construction for the future. Cultivate the ways of rectitude, foster nobility of spirit, and work with resolution – so that you may enhance the innate glory of the imperial state and keep pace with the progress of the world.

(Hirohito's signature and Privy Seal)

Tokyo, August 14, 1945"
