Some people continue to claim that the Japanese peace feelers in the months leading up to Hiroshima were all meaningless low-level approaches with no high-level support. In fact, this is a standard talking point among authors who defend the nuking of Japan. However, there are government records and plenty of scholarly studies that refute this claim. I will summarize some of the facts documented in those records and scholarship. These peace feelers, and others, are discussed in detail by John Toland in The Rising Sun, by Lester Brooks in Behind Japan’s Surrender, and by Gar Alperovitz in The Decision to Use the Atomic Bomb.
-- Very few books on WWII mention the fact that in May 1945, Radio Tokyo’s English-language broadcast, which operated under government supervision, stated that if the Americans would drop their demand for unconditional surrender, Japan’s leaders might be willing to enter into negotiations to end the war (Marco Heinrichs and Galliccio, Implacable Foes: War in the Pacific, 1944-1945, Oxford University Press, 2017, p. 15). This was an astounding statement to be aired on a radio station monitored by all the Allies and by much of Asia. However, Truman and his Japan-hating Secretary of State, James Byrnes, ignored it.
-- In April 1945, none other than Mamoru Shigemitsu, Japan’s Foreign Minister at the time, approached the Swedish minister to Japan and asked if Sweden would be willing to mediate a surrender agreement with the U.S. Now, I would say that a peace feeler done by Japan’s Foreign Minister was both official and very high level.
Shigemitsu’s effort did not succeed, but that was only because his successor, Foreign Minister Shigenori Togo, believed that a more powerful intermediary should be approached. Togo did not object to the approach on principle, but only to the proposed intermediary. Togo suggested that the Soviets be approached to mediate a surrender with the U.S.
-- Another peace feeler was carried out in Berne, Switzerland, by Yoshiro Fujimura, the Japanese naval attache in Berne, and had the backing of Admiral Mitsumasa Yonai, the Navy Minister; General Shuichi Miyazaki, the Chief of Operations; and Admiral Sokichi Takagi, who even offered to fly to Switzerland to open formal negotiations. On May 3, three months before Hiroshima, Dr. Heck, the German intermediary in the approach, was informed by the office of Allen Dulles that the U.S. State Department had authorized direct negotiations with the Fujimura group. Allen Dulles was the head of the OSS office in Switzerland and had numerous high connections, including in the White House.
Fujimura contacted the Navy Ministry and made them aware of his negotiations with the Dulles people. On May 23, the Navy Ministry sent Fujimura a reply, signed by the Navy Minister: the ministry advised him to be cautious but did not shut down the approach.
Yonai then informed Foreign Minister Togo of the negotiations, and Togo authorized Yonai to have the Fujimura group explore the Dulles proposal more thoroughly.
So the claim that the approach to Dulles was some meaningless low-level effort that had no backing in Tokyo is demonstrably incorrect. The hardliners eventually succeeded in killing the Fujimura approach to Dulles, but it was not a meaningless effort with no high-level support. In addition, the hardliners would not have been able to kill it if Truman, or a high official at Truman’s direction, had simply advised the Japanese that we would not depose the emperor if they surrendered according to the terms of the Potsdam Declaration.
We know that on June 4, two months before Hiroshima, Truman received a report on this peace feeler. The report stated that the Fujimura people “particularly stress” the need to maintain the emperor in any surrender in order “to avoid Communism and chaos.” The report added that Fujimura had emphasized the fact that Japan could no longer supply herself with “essential foodstuffs,” i.e., the people were beginning to starve.
On June 22, Truman received another memo on the Fujimura-Dulles peace talks. The memo advised him that “Fujimura insists that the Japanese, before surrendering, would require assurances that the Emperor would be retained.”
So Truman knew, long before Hiroshima, that the only real obstacle to a surrender was his refusal to assure the Japanese that the emperor would not be deposed if they surrendered.
-- The second peace feeler in Switzerland involved General Seigo Okamoto, the Japanese military attache in Berne, and two Japanese officials at the International Bank of Settlements in Basel, in July 1945. Not only was Okamoto a general and the head of the Japanese attache office in Berne, he was a close friend of General Yoshijiru Omezu’s, the Japanese Army Chief of Staff. This feeler also involved Per Jacobsson, a Swiss bank director. This was not Jacobsson’s first involvement with back-door peace negotiations: he had persuaded De Valera to negotiate with the British in 1935.
This approach was made to Gero Gaevernitz, Dulles’s second-in-command, and to Dulles himself. Gaevernitz was no stranger to back-door negotiations either: he had recently masterminded the surrender of all German forces in Italy.
When Jacobsson met with Dulles and Gaevernitz, he told them that the Japanese moderates were doing their best to bring about a surrender but that the Allied demand for unconditional surrender was greatly helping the hardliners. Jacobsson further told Dulles that the only real Japanese condition for surrender was that the emperor not be deposed. Following this meeting, Dulles placed a call to Potsdam.
We also know that on July 13, nearly a month before Hiroshima, Dulles sent a message about his contact with Jacobsson to Potsdam in which he advised that it had been indicated to him that “the only condition on which Japan would insist with respect to surrender would be some consideration for the Japanese Imperial family.”
William Donovan, the head of the OSS, sent a follow-up message to Truman on July 16 about the Dulles-Jacobsson meeting and stated that Jacobsson advised that Japanese officials had stressed only two conditions for surrender, namely, that the emperor be retained and that there be the “possibility” of retaining the Meiji Constitution.
-- Furthermore, Emperor Hirohito himself authorized the effort to get the Soviets to mediate a surrender with the U.S., and Truman was aware of this fact from Foreign Minister Togo’s July 12 cable. Hirohito even wanted to send Prince Konoye to Moscow as a special envoy to get the Soviets to mediate a surrender deal with the U.S. I’d say that a peace feeler pushed by the Foreign Minister and strongly backed by Emperor Hirohito was about as substantial, official, and high ranking as you could get.
Incidentally, the U.S. State Department’s Office of the Historian website includes an article on the Japanese peace feelers, and it documents that American high officials were aware of these efforts:
The contents of certain of these papers [Japanese messages and memos about the peace feelers] were known to United States officials in Washington, however, as early as July 13 (see Walter Millis, ed., The Forrestal Diaries(New York, 1951), page 74; cf. pages 75–76) and information on Japanese peace maneuvers was received by Secretary of War Henry L. Stimson at Babelsberg on July 16 (see volume II, document No. 1236, footnote 4). It has also been determined that a series of messages of Japanese origin on this subject was received by the United States Delegation during the course of the Berlin Conference and that these messages were circulated at Babelsberg to some members of the President’s party. Furthermore, in a conference on January 24, 1956, between Truman and members of his staff and Department of State historians, Truman supplied the information that he was familiar with the contents of the first Japanese peace feeler (i.e., the proposal contained in document No. 582) before Stalin mentioned it to him at Babelsberg (see volume II, page 87) and that he was familiar with the contents of the second Japanese peace feeler (i.e., the approach reported in document No. 1234) before Stalin brought it to the attention of Truman and Attlee at the Tenth Plenary Meeting of the Berlin Conference on July 28 (see volume II, page 460).
