The suspect allegedly earned ¥5 million from the videos

A man has been arrested in Japan for forcing his 13-year-old daughter to appear in child pornography videos.

The Japan News reports that the self-employed man was arrested by Tokyo police in Hyogo Prefecture along with two others.

The 46-year-old father had forced his eldest daughter, 13, to be filmed for five years since she was 8-years-old.

A 57-year-old freelance camera man and a 47-year-old owner of a production company were arrested with the father. All three admitted violating the law against child prostitution and pornography.

The young girl said she did not want to appear in the videos but was forced to film for the income of her family.

Her father dressed his daughter in transparent and tiny swimming suits for the videos in February 2015. He allegedly earned ¥5 million from the videos.

The Metropolitan Police Department suspects the girl was forced to appear in 12 videos in five years. 18,000 copies were marketed.

Her mother was also allegedly aware of the videos. The police are considering building a case against her too.
