Well yes, sort of….but not really.
However, that’s part of the reason for the popularity of Enjo kyosai (援助交際) aka “compensated dating” where high school-aged girls are paid by older men to “date” them (and render sexual services generally).
Here’s the way the so-called “age 13 is age of consent” works:
The age of consent in Japan is 13 years old under the Japanese national criminal law code. However, all municipalities and prefectures have their own particular laws such as Tokyo’s “Youth Protection Law” which prohibit adults from having sex with youths who are under 17 years old. Because the age of consent in Japan ranges from 13 to 18, depending on jurisdiction, many enjo kyosai clients cannot be charged with statutory rape. See the website:
Japan — Age of Consent
Although the age of sexual consent in Japan is 13 years of age, prefecture law usually overrides federal law, raising the age up to 18.
As an added note, even though the age of consent in Japan can be 13, the age of majority is 20 for voting. The age of adulthood is considered 20 and driving age is 18.
Weird? Here’s a better one. Japan’s “Prostitution Prevention Act”(1958) only prohibts actual sexual
intercourse (or sex controlled by organized crime). That law defines as That law defines as “true” sexual conduct between men and women, and not to “imitation” between same sex persons, so gay prostitution is not prohibited directly. That also makes hand jobs, water queens, or homosexual SM nuns legal.
Therefore, creatively kinky places like the “Sexual Harassment Corporation” where you pay to molest girls in school and business sets are totally legal.
