The key individual in the "undergrounds" was Lieutenant General , chief of the intelligence department at Imperial General Headquarters at the end of the war. Shortly before the end of the war, Arisue began collecting intelligence documents to use as a bargaining chip with the Occupation.

SCAP sentiment toward Arisue was mixed, and officers outside G-2 considered indicting Arisue as a Class A war criminal. Willoughby, however, had met and liked Lieutenant General Kawabe Torashiro who had been head of intelligence for the Kwantung Army, military attaché to Berlin, deputy chief of staff for Imperial GHQ, and the leader of the surrender delegation to Manila.

Willoughby asked Arisue, in September 1945, to set up a domestic intelligence network to warn of a potential Communist coup. Ironically, Willoughby was unaware that Arisue and some of his associates, at various times, considered right-wing coups against the Japanese government.
