TOKYO - The Toyama No. 5 apartment block is quiet at midday -- laundry flapping from balconies, old people taking an after-lunch stroll. But the building and its nearby park may be sitting on a gruesome World War II secret.
A wartime nurse has broken more than 60 years of silence to reveal her part in burying dozens, perhaps hundreds, of bodies there as American forces occupied the Japanese capital.
The way experts see it, these were no ordinary casualties of war but possible victims of Tokyo's shadowy wartime experiments on live prisoners of war -- an atrocity that the Japanese government has never officially recognized but that is well-documented by historians and participants.
