A little after noon Japan Standard Time on August 15, 1945, Emperor Hirohito's announcement of Japan's acceptance of the terms of the Potsdam Declaration was broadcast to the Japanese people over the radio. Earlier the same day, the Japanese government had broadcast an announcement over Radio Tokyo that "acceptance of the Potsdam Proclamation [would be] coming soon", and had advised the Allies of the surrender by sending a cable to U.S. President Harry S Truman via the Swiss diplomatic mission in Washington, D.C. A nationwide broadcast by Truman was aired at seven o'clock p.m. (daylight time in Washington, D.C.) on Tuesday, August 14, announcing the communication and that the formal event was scheduled for September 2. In his announcement of Japan's surrender on August 14, Truman said that "the proclamation of V-J Day must wait upon the formal signing of the surrender terms by Japan".
