Japanese war crimes
The U.S. officially classified all 3,649 military and civilian casualties and destruction of military property at Pearl Harbor as non-combatants as there was no state of war between the U.S. and Japan when the attack occurred. Joseph B. Keenan, the chief prosecutor in the Tokyo Trials, says that the attack on Pearl Harbor not only happened without a declaration of war but was also a treacherous and deceitful act. In fact, Japan and the U.S. were still negotiating for a possible peace agreement which kept U.S. officials very distracted when Japanese planes bombed Pearl Harbor. Keenan explained the definition of a war of aggression and the criminality of the attack on Pearl Harbor:
Kazuo Sakamaki
Sakamaki was one of ten sailors (five officers and five petty officers) selected to attack Pearl Harbor in two-man "Ko-hyoteki" class midget submarines on 7 December 1941. Of the ten, nine were killed (including the other crewman in his submarine, Kiyoshi Inagaki). He had been chosen for the mission due to his large number of siblings. Sakamaki had set an explosive charge to destroy his disabled submarine, which had been trapped on Waimanalo Beach, Oahu. When the explosives failed to go off, he swam to the bottom of the submarine to investigate the cause of the failure and became unconscious due to a lack of oxygen. The book "Attack on Pearl Harbor" claims that his sub hit four coral reefs and sank. Sakamaki was found by a US soldier, David Akui, and was taken into military custody. When he awoke, he found himself in a hospital under US armed guard. Sakamaki became the first Japanese prisoner of war in US captivity during World War II and was stricken from Japanese records and officially ceased to exist. His submarine was captured intact and was subsequently taken on tours across the United States as a means of encouraging the purchase of war bonds.
