Quis custodiet ipsos custodes? Who will watch the watchmen?
It's a rare Tokyo Kinky article that begins with a Latin quotation, but sometimes the story justifies such a flourish. And this one is almost stranger than fiction.
Superintendent Koji Tsujimoto has been arrested on suspicion of sexually assaulting an underage girl. He was a leading figure in Osaka police's "eliminate sugar daddy crime" squad, but it turns that he was himself engaged in sugar daddying (papakatsu) with the girl.
The 53-year-old, who was part of the Osaka Prefectural Police Headquarters Public Safety Special ...
Foreign men account for 70% of clients for some Kabukicho prostitutes

/ Tadashi Anahori
The post-COVID uptick in streetwalkers in the Okubo Park area of Kabukicho, Tokyo, has been a media obsession for some time in Japan, generating a moral panic over the young age of the women and also some embarrassment because it has coincided with the huge rise in tourist numbers in Japan.
In the age of social media, going to rubberneck the lines of prostitutes at Okubo Park has become an activity for tourists to do as well as contributed to the notion that Tokyo is already a destination for sex tourism like Bangkok. Of course, approaching women on the street does not come without risk and ...
Police crack down on prostitution spike in Osaka

While much of the current police and media obsession with young female streetwalkers has focused on the Okubo-Kabukicho area of Tokyo, Osaka is also experiencing an apparent increase in visible prostitution.
And just as police are cracking down on both the sex workers and scouts in Kabukicho, the authorities in Osaka are targeting concafes ("concept cafes" -- a kind of "lite" version of a host club) and pimps who prey on young delinquents and runaways near the Dotombori canal, and even redesigning a street to deter streetwalkers.
This has not solved the problem, it seems, because police are ...
Four Okubo Park prostitutes arrested for defrauding foreign men

/ Tadashi Anahori
The moral panic about young prostitutes in Okubo Park near Kabukicho in Shinjuku, Tokyo, just took a new twist with the arrest of four women for defrauding men, especially foreign tourists.
Ongoing for some time, the Okubo Park issue has been a big news story, filled with salacious detail about young women standing around in the area, waiting for men to pick them up for money. While there's nothing new about prostitution in Kabukicho, it is rare to see so many young Japanese women openly engaged in sex work (most streetwalkers tend to be Chinese, since it is more dangerous and public). Such ...
Shocking details emerge about Osaka prostitution ring’s “tours”
July 9, 2025

More details are emerging about the prostitution ring that preyed on young women in Osaka.
As reported widely last month, police arrested Yusuke Kimura (34) and Koki Hideshima (24) for recruiting teenaged girls, violating the Anti-Prostitution Law and Child Welfare Law.
The girls were recruited from the Gurishita area of downtown Osaka (a district known as Minami). Gurishita is the spot near the Dotombori canal under the famous Glico Man billboard. It has become a notorious gathering place for underage delinquents and runaways, and a hotbed of prostitution and crime. Commentators have ...
Police crack down on vast sex worker recruitment network

Crime doesn't pay, they say, but it seems that's not true if you're in the recruitment racket for prostitutes.
According to multiple media reports, a scouting group called Access introduced 78,000 women to sex work at around 1,800 establishments nationwide over a five-year period from 2019. Let those numbers sink in: 78,000 women and 1,800 brothels.
Access earned ¥6 billion in commission, police estimate.
The scout group had contracts with adult entertainment establishments nationwide, and recruited women via social media. They expanded their influence by sending women's profiles, such ...
Doctor arrested for exposing himself on bullet train

While train gropers (chikan) are a well-known problem in Japan, people exposing themselves (particularly men to younger women) is another variant that combines the thrill of exhibitionism with the crueler fetish of enjoying the discomfort it induces on a vulnerable woman.
The classic choice of locations for such flashing is a public park, but it is also often done on a crowded train where the victim has no way to escape.
A train like the Shinkansen, which provides high-speed, long-distance rail services across Japan, might seem like an illogical choice. After exposing himself, the man has ...
Sex worker arrested for threatening to kill family of older lover

If you're dating a sex worker half your age, chances are things are going to get complicated.
And so it proved for a man in his fifties in the west of Shizuoka Prefecture, who was involved with a 22-year-old sex worker in the nearby city of Shimada.
According to a report by SBS on June 9, the unnamed woman was arrested on June 8 for sending a message in which she threatened to kill the man and his family.
"I'll kill you and your whole family," she allegedly wrote in a message to the man sent on the app LINE.
The woman works at a local brothel. It is not known how she and the man began ...
University professor arrested for running brothel and extorting woman

University teachers are generally seen as figures of respect in Japan, like elsewhere, but they sometimes do things that seriously endanger that status.
Who can forget the Taisho University educator who was found wandering the campus in the buff, having been ordered to strip off by his student lover?
But the case of a 49-year-old associate professor at the University of Toyama's Information Technology Center trumps that.
Toyama police re-arrested Hiroshi Takitani, a natural disaster and computational scientist, on June 2 on suspicion of fraud and extortion, having already been charged with ...
Man arrested for urinating on children’s bicycles and helmets

A Japanese man has been arrested for public indecency after exposing his lower body to a woman on the streets of Hongo, Tokyo, in January.
The 29-year-old Masaya Yamada was arrested in April, though the crime was only reported this week in the Japanese media. The incident took place on the night of January 18. The victim was a woman in her twenties.
It seems that the arrest also led police to discover other crimes carried out by Yamada in previous months.
In addition to silently exposing himself in January, Yamada is accused of getting sexual pleasure from urinating on children's bicycles ...
