What was left of Japan's factories and workshops struggled fitfully to turn out weapons and other goods from inadequate raw materials. (Oil supplies had not been available since April.) By July about a quarter of all the houses in Japan had been destroyed, and her transportation system was near collapse. Food had become so scarce that most Japanese were subsisting on a sub-starvation diet.
On the night of March 9-10, 1945, a wave of 300 American bombers struck Tokyo, killing 100,000 people. Dropping nearly 1,700 tons of bombs, the war planes ravaged much of the capital city, completely burning out 16 square miles and destroying a quarter of a million structures. A million residents were left homeless.
Even before the Hiroshima attack, American air force General Curtis LeMay boasted that American bombers were "driving them [Japanese] back to the stone age." Henry H. ("Hap") Arnold, commanding General of the Army air forces, declared in his 1949 memoirs: "It always appeared to us, atomic bomb or no atomic bomb, the Japanese were already on the verge of collapse." This was confirmed by former Japanese prime minister Fumimaro Konoye, who said: "Fundamentally, the thing that brought about the determination to make peace was the prolonged bombing by the B-29s."
In mid-April [1945] the [US] Joint Intelligence Committee reported that Japanese leaders were looking for a way to modify the surrender terms to end the war. The State Department was convinced the Emperor was actively seeking a way to stop the fighting.
In an article that finally appeared August 19, 1945, on the front pages of the Chicago Tribune and the Washington Times-Herald, Trohan revealed that on January 20, 1945, two days prior to his departure for the Yalta meeting with Stalin and Churchill, President Roosevelt received a 40-page memorandum from General Douglas MacArthur outlining five separate surrender overtures from high-level Japanese officials. (The complete text of Trohan's article is in the Winter 1985-86 Journal, pp. 508-512.)
This memo showed that the Japanese were offering surrender terms virtually identical to the ones ultimately accepted by the Americans at the formal surrender ceremony on September 2 -- that is, complete surrender of everything but the person of the Emperor. Specifically, the terms of these peace overtures included:
Complete surrender of all Japanese forces and arms, at home, on island possessions, and in occupied countries.
Occupation of Japan and its possessions by Allied troops under American direction.
Japanese relinquishment of all territory seized during the war, as well as Manchuria, Korea and Taiwan.
Regulation of Japanese industry to halt production of any weapons and other tools of war.
Release of all prisoners of war and internees.
Surrender of designated war criminals.
Summarizing the messages between Togo and Sato, US naval intelligence said that Japan's leaders, "though still balking at the term unconditional surrender," recognized that the war was lost, and had reached the point where they have "no objection to the restoration of peace on the basis of the [1941] Atlantic Charter." These messages, said Assistant Secretary of the Navy Lewis Strauss, "indeed stipulated only that the integrity of the Japanese Royal Family be preserved."
