On May 18, 1936, the infamous Sada Abe Incident (阿部定事件) occurred. Abe, previously a low-ranking geisha, waitress, and on-and-off prostitute, murdered her lover (and former employer) Kichizo Ishida after a marathon of lovemaking at an Ogu inn. Abe, jealous of Ishida’s wife and his associations with other women, had threatened him several days prior with a kitchen knife. This threat was not taken very seriously and they fell back into their usual activities…which now included experiments in erotic asphyxiation. Two days prior to the murder, half-asleep after taking some sedatives, Ishida told Abe “You’ll put the cord around my neck and squeeze it again while I’m sleeping, won’t you…? If you start to strangle me, don’t stop, because it is so painful afterward.”
On the night of the incident, Ishida was again asleep and Abe strangled him to death with her obi cord. Several hours later, she severed his genitals with the kitchen knife and wrapped them in a magazine. She also carved her name into his left arm and, using blood, wrote “Sada and Kichi together” on his left thigh. She was apprehended two days later (along with Ishida’s penis, which she had attempted to use) and taken into custody with no regrets for her actions.
"I loved him so much, I wanted him all to myself. But since we were not husband and wife, as long as he lived he could be embraced by other women. I knew that if I killed him no other woman could ever touch him again, so I killed him….."
