@SotiCoto at 16 a girl is allowed to get married so I guess. I also heard the age of consent was 13. But its still kinda messed up because he's borderline a sexual predator based on their first encounter.
The urban legend about 13 being legal in Japan is technically true, but it’s only in certain areas and under certain conditions. The rule that more commonly applies is 16 with parents’ consent, and I’m pretty sure that’s how this story will play out.
According to Japanese law, age of consent for intercourse is 16, I believe, but sexual favors are legal and age of consent for those is 13. So yeah, very different from America.
