The Imperial Japanese Army’s notorious medical research team carried out secret human experiments regarded as some of the worst war crimes in history.
Its scientists subjected more than 10,000 people per year to grotesque Josef Mengele-style torture in the name of science, including captured Russian soldiers and downed American aircrews.
The experiments included hanging people upside down until they choked, burying them alive, injecting air into their veins and placing them in high-pressure chambers.
Now new detail about their victims’ suffering could be revealed after the authorities in Tokyo announced plans to open an investigation into human bones thought to have come from the unit.
A new search is also due to be carried out for mass graves that may contain more victims of human experiments.
The bones are thought to be from up to 100 people and were discovered in a mass grave in 1989 during construction work.
