Thought this might be of interest.
Thomas Conlan is a Stanford trained historian who did his work on injury reports of BUSHI after battles. He wrote a very entertaining piece (http://126.96.36.199/search?q=cache...n&ie=UTF-8</a>
) which rather pillories the concept of the self-sacrificial warrior.
He has also published a book called In Little Need of Divine Intervention: Takezaki Suenaga's Scrolls of the Mongol Invasions of Japan (Cornell East Asia Series, No 113)
