WW11 Japanese mass grave on Iwo Jima

Japanese officials bow at a mass grave site on Iwo Jima island on Dec. 14, 2010 where the remains of Japanese soldiers, who died in the battle for Iwo Jima, have been discovered.

In a rare visit to Iwo Jima, now known in Japan as Ioto , Japan's Prime Minister offered prayers at two recently discovered mass grave sites and vowed to find the more than 12,000 fallen soldiers whose bodies have yet to be recovered from the remote island where some of World War II's fiercest fighting took place.
