Japan is starting to excavate the site of a former medical school that may reveal grisly secrets from World War II.
The investigation begins Monday at the former school linked to Unit 731, a germ and biological warfare outfit during the war. Shadowy experiments conducted by the unit on war prisoners have never been officially acknowledged by the government but have been documented by historians and participants.
It is the first government probe of the Tokyo site, and follows a former nurses revelation that she helped bury body parts there as American forces began occupying the capital at the end of the war.
Health Ministry official Kazuhiko Kawauchi said the excavation is aimed at finding out if anything is buried in the plot.
"We are not certain if the survey will find anything," Kawauchi said. "If anything is dug up, it may not be related to Unit 731."
