Dozens or hundreds of female Japanese nurses participated in vivisections in China and Japan along with doctors.
The Japanese surgeon Yuasa was with a team of Japanese nurses and doctors when he said two Chinese men in ragged hemp clothing with their hands tied behind their backs were brought to an operating table. One of them struggled at the operating table and stretched his body to avoid lying down. A Japanese nurse walked up to them and she told him in broken Chinese to "lie down, I'll give you anesthetic, it won't hurt" and she pressed him on his back onto the operating table and smiled at him while she did it. The men were given anesthetic and their clothes were cut off and stripped naked for the vivisections. The men were then vivisected by the nurses and doctors. Yuasa later asked the nurse if she remembered what she did but she was handling so many vivisections by that time she didn't remember the first one.
Another Japanese female nurse Murayama Michiko participated in the vivisection two young Chinese men after administering anesthetic.
Another Japanese female nurse Shizuko Tsutsui participated in the vivisections of American airmen. The Americans thought they were brought in for medical treatment when they saw the nurse and smiled. They were going to get cut up. Alive.
