It is a form of compensated dating called “Enjo Kosai.” Japan is currently ranked as a tier 2 country within the Trafficking in Persons 2017 report that is conducted by the United States Department of State. This is due to the lack of enforcement behind the current policies to prosecute traffickers and protect victims.

After that there is a look at current efforts and current policies in place.
