The book “Flyboys” details the Japanese Imperial Army’s fixation on (pseudo)Bushido and the ‘cult of death,’ as opposed to earlier times, when the first incarnations of the modernized Japanese Imperial Army had a code similar to most Western armies.
In any case, and this is all from memory, the book details an episode where a U.S. Naval Aviator (in George Bush I’s sqaudran) was shot down over Chichi Jima, Iwo Jima’s sister island that was not invaded, but instead was to be isolated and neutralized via a series of airstikes on it’s radar, listening posts, and communication stations. One or two of the pilots survived and were captured by I believe a contingent of mixed Imperial Navy and Army units. At least one of the men was forced to serve as an additional translator with the Japanese Naval Intelligence section, and was actually befriended by an American born (Nisei) Japanese sailor that had been drafted as his family returned to Japan prior to hostilities. After a time, the drunken, tyrannical IA commander said the man was to be executed and consumed, purely for ceremonial purposes as they indeed had enough food. Something about showing solidarity with the starving troops languishing on bypassed Pacific atolls. Most of the Japanese enlisted and junior officers were horrified, and refused to partake in the eating of human flesh, but his friend saved part of his liver and made it into a sort of shrine I believe.
Maybe I’ll page through the book and typed some extracts, unfortunately, I don’t have a scanner…
