Approximately 70 people attended the event in Tokyo's Suginami Ward on May 18 to watch five individuals chow down on Sugiyama's cooked privates.
While cannibalism is not illegal in Japan per se, health officials in Tokyo are now investigating the event. According to The Mainichi, health officials are investigating to see if any food hygiene laws were broken during the event; however, the event sponsor said that no laws were broken in eating a human body part that was legally removed by a medical institution.
The Mainichi does not point out that, like in most countries, it's illegal to sell one's organs in Japan, which puts this meal in gray legal territory. You cannot even sell your own blood (blood donors get free drinks, instead). But, hey, charging people to eat your body parts is cool as long as you don't break hygiene laws? Sounds like a legal cock-up.
