Ex-Real Estate Chairman Caught in Risky Drugged Sex Business Targeting Underage Girls

【Warning Report】The Ruthless Tactics of Black-Market Operators Raking In 100,000–300,000 Yen a Night

Please look at the photo below. Next to a man in a bathrobe, a woman stands with her head bowed, her arms hanging lifelessly at her sides as if drained of vitality. In a video obtained by the author from someone connected to the case, the entire scene of a drug party spreading through the nightlife district was captured.

The man in the photo is Tsuyoshi Tanaka (60), former chairman of the real estate investment company Raceam. On June 24 last year, in a luxury hotel room in Tokyo’s Chiyoda Ward, Tanaka was found in possession of stimulants and cocaine. He was arrested on May 12 this year on charges including violation of the Stimulants Control Act.

“In this case, a former race queen, referred to as A, and a current female university student, referred to as B, who were in the same room, were also arrested (though both were not indicted). Police suspected that the three of them possessed and used drugs together inside the hotel room,” said a reporter from a national newspaper’s social affairs department.

An entrepreneur who built a listed company from scratch, a former race queen, and a university student—what linked these three people, who seemingly had nothing in common, was a broker who sent women to male clients for sex involving illegal drugs, known as kimeseku (drug-fueled sex). Mr. X, a street scout based in Roppongi, revealed this.

“I heard that A and B were dispatched to Tanaka through the same scouting group. This group mainly recruited women for the sex industry and cabaret clubs, but in recent years, they also started dispatching women specifically for kimeseku.”

Among underground brokers, Tanaka was known as a big-spending client.

“The going rate for dispatching a kimeseku partner is about 100,000 to 300,000 yen per woman per night, but there were rumors for over a year that a certain big client was paying several million yen. And apparently, that client wasn’t very interested in the sex itself—he preferred to have women engage with each other, or simply watch women becoming intoxicated under the influence of drugs. It was only after the case was reported that I learned this big spender was Tanaka of Raceam,” said another street scout, Mr. K.

The drugs commonly used for kimeseku include stimulants, cocaine, and MDMA, all said to produce pleasure tens or even hundreds of times greater than ordinary sex. Mr. K added, “It’s the intensity of that pleasure that makes kimeseku so dangerous.”

“Once you experience the euphoria of kimeseku, it imprints itself on the brain and can never be forgotten. Resisting the temptation is not easy, and once someone gives in, they fall as far as they can fall.”

They even deceive underage girls in “Toe-Yoko” to find partners

The business of dispatching “kimeseku” (drug-sex) partners has flourished since the COVID-19 pandemic.

“Before, it was common for drug addicts to look for partners on online forums or to be introduced through familiar dealers. Women who agreed saw benefits such as getting pocket money while using drugs for free. However, some would turn the tables and threaten their partners with lines like ‘I’ll call the police’ to extort money.

That’s why demand grew among wealthy clients for dispatched kimeseku partners who were somewhat reliable with verifiable backgrounds. During the pandemic, many sex clubs and hostess bars were shut down, leaving women without work. Scout agencies spotted the opportunity and began supplying women as kimeseku partners, which fueled the boom. Most agencies acquired customers through word of mouth among clients or through drug dealers. Recently, some even target visiting foreigners, particularly Chinese tourists.”

So who are the women actually being sent out?

“Some are drug addicts, while others are sex workers who can no longer earn as much as they used to. But some clients prefer not professionals but ordinary women. In such cases, brokers lure women with high pay or deceive them with lines like ‘You don’t even have to do drugs,’ sending women with no prior experience in sex work or drugs.

In the Toe-Yoko district, there are people pretending to be youth protection volunteers, approaching underage girls and recruiting them as kimeseku partners. Once a woman experiences it, she often gets hooked and starts asking, ‘When’s the next job?’”

One woman in her twenties recalls a terrifying night after being tricked by a broker:

“I was promised an unbelievable 500,000 yen for one night, and they said I wouldn’t have to have sex. But when I arrived, a middle-aged client heated white powder on a spoon and told me to inhale the smoke. I only pretended to, but then he subjected me to hours of touching and caressing without climaxing. It was pure torture.”

Attorney Hirotaro Kato of the Kato-Todoroki Law Office warns:

“Brokers often scare women by saying things like ‘You’re an accomplice too,’ discouraging them from reporting to the police. This isn’t an empty threat—there have been cases where women forced to take drugs were themselves arrested for drug use. Many women suffer repeated abuse because they’re too afraid to speak out.”

Kimeseku destroys everyone involved. Never get entangled in it.
