A 39-year-old man, his wife and his common-law wife, who were arrested over allegedly posting secretly filmed sexual videos, shared nearly 1,000 such videos and photos online, investigative sources said Tuesday.

The man, Yohei Ono, 39, his wife, Haruka, 28, and his common-law wife, Rin, 24, who is also his adopted daughter, claim that they have been living together as a polygamous family.

Ono was arrested by Tokyo＊s Metropolitan Police Department in November for allegedly confining a woman under 20.

His wife and common-law wife were arrested in the following month on suspicion of secretly filming Ono having sexual intercourse with a woman in her 20s and posting the footage on a video-sharing site. Ono was then served with a fresh arrest warrant on the same charges.

On Tuesday, the police served new arrest warrants for the three for allegedly secretly filming him having sex with another woman in her 20s at a hotel in Tokyo＊s Shinjuku Ward on June 23, 2024, and sharing the video through online video platform Myfans on Oct. 26 the same year.

The three are believed to have earned more than ?55 million by selling the secretly filmed videos online. Ono has admitted to the allegations, while the other two suspects have remained silent.

The police said that the woman in the 2024 case and Ono came to know each other through social media and met several times.

The police informed the woman that she had been secretly filmed. She told them that she was ordered to pay ?3 million in consolation money for having an extramarital affair.

The three are believed to have filmed the intercourse by setting up a camera disguised as a fire alarm and hiding other equipment behind framed paintings and boxes of tissues in a hotel room.

Over 860 sexual videos featuring about 100 women have been found at related places, and police confirmed that around 1,000 videos were shared on a paid membership website. Some of the videos have already been deleted.

The three are also suspected of operating a honey trap scheme.
