A Leadership That Kept Moving
To brief its executives, Japan's largest illegal scout organization did not use an office. According to investigators cited in reporting on July 7, 2026, the group known as "Natural" convened its leadership in rented meeting rooms and karaoke boxes, changing the location each time—an arrangement police now describe as a deliberate effort to stay ahead of surveillance.
On July 7, the Metropolitan Police Department (MPD) re-arrested three men said to sit at the top of that structure on suspicion of violating the Employment Security Act (shokugyo anteiho), the statute that bars placing people into work harmful to public health or morals. The arrests were reported by the TBS network (JNN), Jiji Press, the Hokkaido Shimbun and the Shimotsuke Shimbun, among others.
The reported details are allegations at the investigative stage; no indictment or finding of guilt has been established.
Who Was Re-Arrested
According to the reports, those taken back into custody are Hiroaki Obata, 41, described as the group's chairman; Yuto Enomoto, 35, said to be its No. 2; and a 27-year-old man identified by the surname An, described as an executive of the group's collection-and-accounting division.
The re-arrest allegations, as reported:
| Suspect | Role (as reported) | Alleged act |
|---|---|---|
| Hiroaki Obata, 41 | Chairman | With An, conspired to refer a woman in her 20s to a sex-industry establishment in Chiba City, around late May two years ago |
| An, 27 | Collection/accounting executive | Same alleged referral as above |
| Yuto Enomoto, 35 | No. 2 | Referred a woman in her 20s to a non-storefront (delivery-type) sex business in Takasaki, Gunma, in early-to-mid January two years ago |
The MPD has not disclosed whether the three admit or deny the allegations.
What the Law Targets
The Employment Security Act is being used here in a specific way. Rather than charging the sale of sex itself, it reaches the intermediary—the person who places a worker into an occupation the law deems harmful. Introducing women to unlicensed adult-entertainment establishments falls within that prohibition, which is why a "scout" who never touches a customer can nonetheless be the defendant.
That framing is central to how authorities have approached scout groups. These organizations do not, as a rule, run the brothels; they feed workers into them and collect a cut of the resulting sales as a referral fee, or "scout back." Cutting the pipeline of referrals is the mechanism through which police aim to starve the businesses downstream.
A Group Built to Be Hard to See
Reporting describes "Natural" as the largest and most established illegal scout network in the country, with an organization said to number in the low thousands and annual revenue estimated at no less than 5 billion yen. Its reach is national, matching women recruited in entertainment districts to establishments across multiple prefectures.
The counter-surveillance detail disclosed on July 7—leadership meetings shuffled among rented rooms and karaoke parlors—fits a pattern that has surfaced repeatedly in coverage of the group: a chairman reported to have changed names and addresses to complicate tracking, and a shift away from in-person gatherings toward app-based communication as police pressure mounted. Taken together, the picture is of an organization that treated its own visibility as an operational risk to be managed.
The Latest in a Rapid Series
The July 7 arrests extend a stop-and-start campaign that has kept the group's leadership in custody for much of the year. Police have moved against "Natural" in stages—brokering, then finances, now brokering again—rather than in a single sweep.
In mid-June, the MPD's Organized Crime Control Division and Chiba Prefectural Police re-arrested Obata and a collection-division executive on suspicion of concealing about 39.2 million yen in criminal proceeds, money investigators said had flowed in from a Chiba soapland under the guise of referral fees and been laundered through receipts issued in another person's name; part of the revenue was believed to have reached an organized-crime group. Enomoto, the No. 2, had earlier been arrested in a separate Employment Security Act case tied to a Gunma referral. Each new arrest has let investigators hold the leadership while building the next charge.
The through-line is a shift in emphasis from the front-line scouts to the people at the top and the money they moved—an approach that treats the group not as a loose collection of recruiters but as an enterprise with a chain of command, a books division, and, as of this week's disclosure, a boardroom that never sat still.
Whether the latest allegations hold will be determined in the course of the investigation and any trial. As with any arrest, the suspects have not been convicted, and the account so far is the authorities'.
