I didn't know that! In that case, it was nothing but genocide, and it was a crime up there with the Nazis' genocides, if not as big.
It's not true. Please read previous posts.
An inner cabinet in Tokyo authorized Japan's only officially sanctioned diplomatic initiative. The Japanese dubbed this inner cabinet the Big Six because it comprised just six men: Prime Minister Kantaro Suzuki, Foreign Minister Shigenori Togo, Army Minister Korechika Anami, Navy Minister Mitsumasa Yonai, and the chiefs of staff of the Imperial Army (General Yoshijiro Umezu) and Imperial Navy (Admiral Soemu Toyoda). In complete secrecy, the Big Six agreed on an approach to the Soviet Union in June 1945. This was not to ask the Soviets to deliver a "We surrender" note; rather, it aimed to enlist the Soviets as mediators to negotiate an end to the war satisfactory to the Big Six--in other words, a peace on terms satisfactory to the dominant militarists. Their minimal goal was not confined to guaranteed retention of the Imperial Institution; they also insisted on preservation of the old militaristic order in Japan, the one in which they ruled.
The conduit for this initiative was Japan's ambassador in Moscow, Naotake Sato. He communicated with Foreign Minister Togo--and, thanks to code breaking, with American policymakers. Ambassador Sato emerges in the intercepts as a devastating cross-examiner ruthlessly unmasking for history the feebleness of the whole enterprise. Sato immediately told Togo that the Soviets would never bestir themselves on behalf of Japan. The foreign minister could only insist that Sato follow his instructions. Sato demanded to know whether the government and the military supported the overture and what its legal basis was--after all, the official Japanese position, adopted in an Imperial Conference in June 1945 with the emperor's sanction, was a fight to the finish. The ambassador also demanded that Japan state concrete terms to end the war, otherwise the effort could not be taken seriously. Togo responded evasively that the "directing powers" and the government had authorized the effort--he did not and could not claim that the military in general supported it or that the fight-to-the-end policy had been replaced. Indeed, Togo added: "Please bear particularly in mind, however, that we are not seeking the Russians' mediation for anything like an unconditional surrender."
This last comment triggered a fateful exchange. Critics have pointed out correctly that both Under Secretary of State Joseph Grew (the former U.S. ambassador to Japan and the leading expert on that nation within the government) and Secretary of War Henry Stimson advised Truman that a guarantee that the Imperial Institution would not be eliminated could prove essential to obtaining Japan's surrender. The critics further have argued that if only the United States had made such a guarantee, Japan would have surrendered. But when Foreign Minister Togo informed Ambassador Sato that Japan was not looking for anything like unconditional surrender, Sato promptly wired back a cable that the editors of the "Magic" Diplomatic Summary made clear to American policymakers "advocate[s] unconditional surrender provided the Imperial House is preserved." Togo's reply, quoted in the "Magic" Diplomatic Summary of July 22, 1945, was adamant: American policymakers could read for themselves Togo's rejection of Sato's proposal--with not even a hint that a guarantee of the Imperial House would be a step in the right direction. Any rational person following this exchange would conclude that modifying the demand for unconditional surrender to include a promise to preserve the Imperial House would not secure Japan's surrender.
Following prompting by Kido, at the emperor’s bidding and in super secrecy the Big Six initiated tentative steps to secure the Soviet Union as a mediator to procure a negotiated end to the war—not to surrender. The feeble effort went nowhere. The “Big Six” never agreed on what terms might be offered to the Soviet Union to act as mediator, much less on terms to end the war. Nor did the emperor intervene decisively to lay down terms for mediation or for ending the war.
