Tokyo police have arrested three people, including a 41-year-old shop owner, for providing sexually suggestive services involving high school girls in apparent violation of labor laws, investigation sources said.

The shop offered so-called "JK" services in which underage girls would fold origami while posing with their legs open and showing their underwear. Male customers would view them through a one-way mirror.

The police raided the shop in March after judging that it ran a "harmful business," offering sexually stimulating services to customers in violation of labor laws.
