Japanese culture was very unique and obedient to ultimate authority (the Emperor was a God, remember). It was this principal, more than any other that allowed their society to survive over 1000 years.

Contrast this with post war Germany.... The Werwolf, Edelweiss Pirates and other insurgent groups murdered pro-Allies government officials and civilians, committed acts of sabotage and by some accounts over 3,000 deaths of occupation troops and subsequent reprisals 1945-46, though this figure has been brought into question. Over 40 US personnel were killed in an explosion in the Occupation Police HQ in Bremen June 1945. This was claimed to be the work of Werwolf, but never proved (or disproved).
