Mao Sugiyama got surgery to remove his genitals, then cooked and served them to five guests.
The artist who cooked and served genitals to a paying group of cannibalistic diners could now face two years in prison.
Mao Sugiyama, of Tokyo, has been charged with indecent exposure more than two months after the headline-grabbing meal, which five patrons shelled out $250 to consume, according to News On Japan.

The 23-year-old self-described "asexual" and three other people who helped organize the event face charges, according to the Metropolitan Police Department.
Before turning 22, Sugiyama underwent elective genital-removal surgery. The severed penis, testicles, and scrotal skin were divided up and garnished with button mushrooms and Italian parsley.
An MPD spokeswoman told AFP that the four suspects conspired to "openly display the severed male genitals to the assembled 71 guests" at a music club on May 13.
Sugiyama made sure to follow all laws, including a ban on organ sales, processing of medical waste and food sanitation requirements, according to comments cited by AFP from the artist.
Sugiyama also said the dinner was designed to raise awareness about "sexual minorities, x-gender, asexual people."
The Japan Daily Press reports that, if convicted of indecent exposure, Sugiyama could face up to two years in jail and a fine of roughly $32,000.
Indecent exposure in Japan is described as displaying obscene objects, according to the Japan Daily Press. The paper seems to hint that the charge is a bit absurd considering people attending the event likely knew what they were in for.
The diners: Dozens showed up to the event in Japan, but most only got to eat crocodile.
