Saipan led to Yiojima and Yiojima may lead to the mainland, warned the Mainichi today. Apparently in preparation for invasion the vice-minister officer, Shibayama, in reply to interpellations in the commons yesterday, revealed that “the fighting services at present are making nationwide preparations for the organization of a defense corps”. This defense corps will be composed of former service-men, with units in every army regional command in Japan. Their arms will be manufactured locally in the different regions. “In case we directly face an enemy invasion,” concluded Shibayama, “not only this defense corps but also the volunteer corps, the patrol corps, and the police forces, etc., will be unified and mobilized.” The volunteer corps refers to another organization proposed by Koiso himself yesterday; details are not yet available but it will be drawn from the people at large, who will be armed and trained to fight as guerrillas.
