A man who ran an online porn DVD store was arrested Monday on suspicion of coercing an 18-year-old woman in Osaka to perform in a porn video after enticing her with an offer to be cast as a cosplay model.

Shinichi Kanazawa, 48, used similar techniques to prey on more than 200 women in Tokyo, Osaka and 17 other prefectures, most of them likely 18 or 19 years old, between 2012 and this year, police allege.

Kanazawa solicited women online to pose as cosplay models for photo shoots, promising to pay ¥50,000 a day, or ¥200,000 if they agreed to work for three days, the police said.
