STOCK: Relatives honour Japanese guards at "Unbroken" prison camp

STOCK: Film of a service to honour the Japanese guards who imposed their reign of terror on Louis Zamperini and other allied prisoners of war during the Second World War. Zamperini's story is told in the movie "Unbroken," but in Naoetsu, where he was held in the latter stages of the Second World War, families of the Japanese prison guards still pay their respects to their menfolk every year on the site of the camp. This rare footage was shot in November 2010.
