The First "Conspiracy Case"
On September 10, 2025, the Metropolitan Police Department and the Osaka Prefectural Police carried out a simultaneous crackdown on organizations that used host-club tab debts to funnel female customers into the sex trade. In Tokyo and Osaka, they arrested a total of 35 people connected to host clubs and the adult-entertainment establishments working with them, on suspicion of violating the Anti-Prostitution Act (causing prostitution and organized/managed prostitution).
A distinctive feature of this investigation was that the host-club side (the role of binding women through tab debt) and the adult-entertainment side (the role of actually putting them to work) were built into a single integrated case as a "conspiracy." It is drawing attention as a legal response to a "structure in which the two sides cooperate to exploit women."
The Reality of the Harm
The women who became victims number more than 60 in confirmed cases alone. They were made to run up an average of 3 to 5 million yen in tab debt at host clubs and were then funneled in with messages such as "earn it back in sex work and pay it off." Referral fees, on a basis such as "XX yen per woman introduced," were also exchanged between the hosts and the adult-entertainment establishments.
Establishing a Legal Framework
This "conspiracy case" breaks new ground in the interpretation of the Anti-Prostitution Act. Authorities moved to arrest and prosecute, finding that the case met the requirement of "causing prostitution by means of confounding/perplexing the victim." If the verdict is finalized, it will become a precedent for handling similar cases in the future.
