Hitherto undiscovered papers from the Imperial Japanese Government during the Second World War, show a kamikaze pilot successfully took legal action against his superiors after developing Pre-traumatic Stress Disorder.
Lt Akira Saito signed up to the suicide squadron in the belief he would recieve the necessary counselling and support for his sacrifice.
But the papers found in a disused archive in Tokyo, show he complained that he didn't and then developed PTSD, before winning a compensation claim against the Imperial Government.
"These are amazing documents." Professor Roger Delgado from the University of Idaho said.
"They show that Lt. Saito turned back on at least five missions before he finally crashed into the Pacific Ocean in an unsuccessful attack on the battleship USS South Dakota. His excuses included low oil pressure and dirty underwear."
The papers are part of a much larger archive which should have been destroyed before the war ended, but documents show it was saved after a clerk refused to incinerate the material, because the order wasn't signed by the Emperor himself.
