Japan's obsession with cutesy culture has taken a dark turn, with schoolgirls now offering themselves for "walking dates" with adult men. Last year the US State Department, in its annual report on human trafficking, flagged so-called joshi-kosei osanpo dates (that's Japanese for "high school walking") as fronts for commercial sex run by sophisticated criminal networks.

In our exclusive investigation, VICE News host Simon Ostrovsky will bring you to one of Tokyo's busiest neighborhoods, where girls solicit clients in their school uniforms, to a concert performed by a band of schoolgirls attended by adult men, and into a café, where teenage girls are available to hire by the hour. But the true revelations come behind closed doors, when schoolgirls involved in the rent-a-date industry reveal how they've been coerced into prostitution.
