Within this early occupation period [from September 1945], MacArthur’s “military secretary” and former head of psychological warfare operations, Brig. Gen. Bonner F. Fellers, reestablished personal ties with two Japanese Quakers. One, Isshiki (Watanabe) Yuri, he had known from his days at Earlham College in Richmond, Indiana; the other, Kawai Michi, a former secretary-general of the YWCA and founder in 1929 of Keisen Girls School in Tokyo, he had met on his first visit to Japan in 1920. During their initial reunion meetings, Fellers spoke frankly of his urgent concern to prove that no grounds existed for holding the emperor responsible for the Pearl Harbor attack. With Kawai acting as his consultant and collaborator, Fellers was soon put into contact with her acquaintance, Sekiya Teizaburô, the high palace official who, since late Taishô, had played a leading role as a liaison between the court and government ministries. Sekiya too wanted to prove that the emperor was a “lover of peace.”
An entirely new, binational stage in the movement to protect Hirohito now began. Out of the interplay of efforts by GHQ, the emperor, Japanese government leaders, and Japanese Christians with prewar ties to influential Americans, came the shielding of Hirohito from war responsibility, his “humanization,” and the reform of the imperial house. Henceforth, in the process of utilizing Hirohito’s authority for their own respective purposes, MacArthur and the Japanese leadership would have to misrepresent a vital side of Hirohito’s life and identity, just as they [had] been misrepresented before the war….
Between April and July 1945, MacArthur and Fellers had worked out their own approach to occupying and reforming Japan. In their view the principles of psychological warfare that Fellers had implemented in the Battle of the Philippines and elsewhere were solidly correct. They had played a key role in lowering Japanese morale, hastening surrender, and preparing the Japanese for occupation. Japanese military leaders alone bore responsibility for the war, and the emperor, the “moderates” around the throne, and the people had been totally deceived by them. All Japanese trusted the emperor. U.S. psychological warfare should build on their trust and turn it against them. These ideas, the “common sense” of American psychological warfare experts in the Pacific, not to mention Chinese and Japanese Communist leaders in North China, had become MacArthur’s fixed principles and were woven into his initial occupation plan.
Code-named Operation Blacklist, the plan turned on separating Hirohito from the militarists, retaining him as a constitutional monarch but only as a figurehead, and using him to bring about a great spiritual transformation of the Japanese people. Because retaining the emperor was crucial to ensuring control over the population, the occupation forces aimed to immunize him from war responsibility, never debase him or demean his authority, and at the same time make maximum use of existing Japanese government organizations. MacArthur, in short, formulated no new policy toward the emperor; he merely continued the one in effect during the last year of the Pacific war, then drew out its implications as circumstances changed.
