20 Years to Jap Who Beat U.S. War Prisoners YOKOHAMA (AP) – It took the Eighth Army military court only a day and a half to hear the war crimes trial of the prisoner of war camp guard, Shinichi Motoyashiki, to find him guilty and to sentence him to 20 years. He pleaded innocent to beating Americans at the Hirohata prisoner of war camp. Motoyahsiki was mentioned in the trial of Kataro Ishida, “The Bull,” and was called to testify against him with the result that Ishida got 30 years. The affair brought Motoyashiki to attention and he was arrested. Motoyahiski became a civilian guard after his discharge from the Japanese navy because of a leg injury. He was found guilty of booting American prisoners of war.
