HARBIN - New evidence of human experiments and germ war crimes by Japan's notorious Unit 731 were released by a museum on Friday in Harbin, Heilongjiang province. The Museum of Evidence of War Crimes by Japanese Army Unit 731 has added written confessions, a transportation record of human experiments, old photos of the unit's soldiers and an incubator for producing plague bacillus.

"The incubator, collected from a resident in Harbin, directly proves 731's atrocities of germ experiments and development," said Jin Chengmin, curator of the museum.

It also verified confessions that the base had a culture room that could produce 10 kilograms of germs in 12 or 24 hours, and four incubators that were used for biological production.
