Sada Abe (?? ?, Abe Sada, May 28, 1905 – after 1971) was a Japanese woman, a geisha and prostitute, who erotically asphyxiated her lover, Kichizo Ishida (?? ??), on May 18, 1936, and then cut off his penis and testicles and carried them around with her in her kimono.
The story became a national sensation in Japan, acquiring mythic overtones, and has been interpreted by artists, philosophers, novelists and filmmakers.
Abe was released after having served five years in prison and went on to write an autobiography.
