A Japanese man has been arrested for making a 13-year-old girl sign a contract to be his “exclusive slave” during a paid encounter at a love hotel.

Tadahiro Daimaru, 29, is accused of paying JPY 50,000 (GBP 324) to the girl at a love hotel in the city of Nagoya in the Japanese prefecture of Aichi on 13th February after meeting her on Twitter about a month earlier.

According to the police, the suspect arranged to meet the 13-year-old girl and got her to sign a four-page ‘slave contract’ that he penned himself.

In the document, Daimaru asked the girl carry out dozens of specific requirements and be his “exclusive slave” and “pledge eternal love” during their time together.

The police said that he even filmed the act on his phone and that at one point he choked the girl.

Daimaru reportedly admitted to the allegations upon his arrest for violating the anti-child prostitution and pornography law.

The police said he was arrested in March for having sex with a different girl while aware that she was underage.

During the March investigation, the incident at the love hotel in Nagoya came to light.

The investigation is ongoing.
