The Human Bullet (1968)

"Kamikaze funeral pyre"

A soldier has been in the Japanese military for the entirety of WWII, and in that time, his dedication to the army has never faltered. However, as the war draws to a close, his commanding officers become increasingly desperate and push their men to ever more absurd extremes. The ridiculousness of the orders from above peak when the hero of the story is assigned to drive a one-man submarine straight into the hull of an enemy battleship.
