Baby, a business referred to by the abbreviation JK, or joshi kosei, meaning high school girl, billed itself as offering massages by girls in uniform. However, a separate menu featured services allowing customers to take the employees out for a stroll, which led to the provision of sex, police said.
Baby charged between 6,000 and 15,000 yen for a basic massage. However, many of the girls, who were recruited via Twitter, permitted sex at a hotel for up to 40,000 yen per session, police said.
