OKI (COL.) Interrogation - May 1947 Oki was a member of Legal Section, War Department, Tokyo, in 1945, transferred to WA Legal Section in Jan. 1946. About 8 American flyers were experimented on with sea water drugs, according to information received from Inada and Sato in Feb. 1946. Oki investigated executions, but not experiments because Inada ordered him not to investigate latter phase, since bad name for WA and KIU and they thought they could conceal KIU incident by Hiroshima story. Oki gave his report over to Tait, with names of Americans. He doesn't know of Suzuki report, but met Suzuki at WA (1) the first of Feb. and (2) the first of War. Unreasonable that Komori was such an important cog. Yokoyama told Oki that he knew nothing of atrocities until end of war; this also unreasonable. Sato, however, told Oki that he consulted with Yokoyama in May or June 45. Oki took Ito's position 17 Dec. by order of Demobilisation Authority, with duties to (1) investigate American flyer cases and (2) to try Japanese Prisoners. He denies Ito's story that he wrote a false report; states that Inada and Akita sent false report to Kurume CIC. Oki wrote a report to the Demobilization Authority, Tokyo, under Inada's orders, which contained information as to 1 June executed and 2 August (??) execution, including names of flyers and Japanese. He reported KIU incident 16-17 April 1946. Inada was worried about his personal position as to the KIU incident. Komori told Sato he had approval of Yokoyama. Oki doesn't recall Sato's telephone to War Department Legal Section at end of war, does recall that Gen. Fujii did order records to be burned. Feb. 1946 Oki questioned Itezona and Murate, wrote his report under orders of Nishihara, who stamped it. Tokyo Headquarters first heard of atrocities about Nov. or Dec. 45, although they might have known about it at the end of the war. Oki got information from Nakamura as to the ashes, which he, Nakamura and Tait dug up. Nakamura burned the bodies on 15 August, said he first put them in a temple, then buried them on a mountain. Yukino was in charge of detention of Prisoners. Nakamura and Yukino buried the ashes. Egawa told Oki that Goiyama told him that several Americans, who were not sick, were sent to KIU, and while Oki wanted to investigate it, Inada would not permit him. After the Doolittle trail, Tokyo sent out orders that flyers were to be tried, recalls that Osaka Central Army did try 2. About Sept, or Oct. 45 Ito orally reported to War Department Legal Section that 30-40 flyers were killed without trial— this was presented to Fujii, Oki and others. Oki first heard of KIU incident about 10 Jan. from Egawa of Legal Section. He heard from Ito and Fukushima of 3 incidents, the 4th from Egawa. Ito reported to War Department Legal Section that 16 flyers killed in June airraid. He believes that operations took place between 15 May and 20 June (Oki). Oki -2- Inada chief of WA at time Oki was there. Oki did talk to Yokoyama, who told him that such treatment of flyers was contrary to WA regulations, that he first heard of atrocities after war. Aburamaya about 20 miles from Yamaie, about same from Fukushima. Tactical operations were assigned to Akita and Inada. Fukushima responsible for 15 August execution. Suzuki found from Fukuoka CIC that they knew nothing of affairs. Sato told him Prisoners were injected with sea water as guinea pigs, did not say they,died. Egawa told him these Prisoners were killed. Yamaie Officers tried to pass buck to Fukuoka Officers and vice versa. |
