Japanese Police Arrest Okayama's Sato and Minazawa for Fraud Involving Fake Police and Cryptocurrency
According to reports from Japan's Fuji News Network and others, the Tokyo Metropolitan Police arrested 31-year-old Sato from Okayama and 38-year-old Minazawa, who are suspected of being involved in a fraud gang impersonating police officers. The gang posed as Osaka Prefectural Police and falsely informed a woman in her 40s that her bank card was linked to approximately 600 billion yen in fraud and money laundering, demanding she "prove her innocence" and allegedly defrauding her of cryptocurrency worth about 81 million yen.
Police stated that the calls originated from a base in Cambodia, with the two acting as "kakeko" (dialers); Minazawa was also accused of interpreting and managing other dialers at the base. The total known losses related to the two amount to approximately 240 million yen. The police believe the mastermind may be of Chinese nationality. The case narrative points to a series of calls made to the aforementioned woman around August last year, with callers claiming to be from the Osaka Prefectural Police, the investigation department, and prosecutors, ultimately demanding the transfer of cryptocurrency.
Such cases are part of a recent trend of fake police scams originating from bases in Cambodia and Thailand targeting Japan: they create a sense of urgency about imminent arrest using large-scale money laundering stories, then guide victims to transfer cryptocurrency as a means of "proving their innocence." The Tokyo Metropolitan Police and local police have repeatedly repatriated and arrested Japanese dialers from Southeast Asia, and this case is one where cryptocurrency, rather than bank transfers, was used as the cash-out channel. The two are currently suspects, and the investigation is ongoing.
In market mechanisms, the buyers are victims who sell or transfer cryptocurrency after being induced into panic, while the sellers are the receiving addresses controlled by the base. Funds flow from personal wallets in Japan to addresses controlled by cross-border gangs, then enter a higher level of aggregation and exchange. The beneficiaries are the base management and the alleged command level, while the burden falls on individuals who convert their savings into cryptocurrency but hand over their private keys or make transfers under the guise of "cooperating with the investigation." The event was driven by arrests in Tokyo, rather than a new on-chain rally.

Japan's special fraud schemes have shifted from bank remittances to cryptocurrency due to tightened bank risk controls, leaving victims with only exchanges and wallets they can operate themselves. The Cambodian base uses Japanese interpreters and dialers to ensure the Osaka Prefectural Police's accent and terminology pass muster; the presence of a Chinese command level in police reports aligns with the personnel structure in Southeast Asian parks since 2025. Minazawa is noted to both make calls and manage people, indicating that Japanese personnel have evolved from pure labor to on-site foremen, but still do not control the funds.
The capital path is the monetization of fear premiums. The unverifiable figure of 600 billion yen is designed to cut off the time victims have to verify with real police, while the 81 million yen for a single case and 240 million yen in total indicate the same set of scripts is being reused. Resources include cheap cross-border calls, scripts, and receiving addresses, rather than any on-chain agreements. The motivation is to extract the layer of savings converted into cryptocurrency from Japanese households, as it becomes increasingly difficult to transfer fiat accounts in one go.
Similar cases include Ethereum scams by fake police repatriated from Indonesia, mass arrests at Cambodian bases in Poipet and Bavet, and U.S. prosecutions of park-level pig slaughter schemes. The industry is in a period of catch-up for cross-border law enforcement: the base is in one country, the victims in another, and the assets on-chain, making it impossible to arrest dialers without cutting off the script layer, while the command and exchange layers remain in another jurisdiction.
Structural judgments belong to regulatory changes. Once the cash-out channel shifted from bank counters to victims' own wallets, police can only arrest individuals upon entry or repatriation, with pricing power residing at the base, not at exchange KYC. The mechanism is: when "proving innocence" is designed to necessitate the transfer of cryptocurrency, the last barrier against fraud becomes whether the victim hangs up, rather than an on-chain contract.

- Money that is hard to transfer through banks will be redirected to cryptocurrency wallets.
- Fake police are not after confessions, but transfers.
- Bases are overseas, so scripts need to have local accents.
