In an effort to crack down on telephone dating clubs that enable users to engage in sex with minors and child prostitution, the National Police Agency is planning to submit a bill to revise a law controlling the adult entertainment business, NPA officials said.

The agency plans to revise the Law Regulating Adult Entertainment Businesses to tighten regulations on such clubs, which often offer services through nonstore operations, by requiring business operators to confirm that users are aged 18 or over.

The NPA is aware of the need to introduce a legal measure to deal uniformly with telephone dating clubs, which are currently regulated under ordinances set by individual prefectures, they said Thursday.
