Nyotaimori, often referred to as "body sushi", is the practice of eating sashimi or sushi from the body of a woman, typically naked. As a result of being served on a human body, the temperature of the sushi or sashimi comes closer to body temperature, which some may see as a disadvantage or a benefit. Wikipedia
