Fraudulent schemes involving the impersonation of police officers, prosecutors, and other officials have been reported across multiple Japanese prefectures.

In Kochi Prefecture, authorities reported that since the beginning of 2026, 28 cases of police impersonation fraud have resulted in damages exceeding 300 million yen. Victims have been coerced into transferring large sums of money under the false pretense of clearing their names from money laundering investigations or arrest warrants.

In Aomori Prefecture, a similar sophisticated scheme was documented where a victim was contacted by individuals posing as postal workers and police officers. The perpetrators used the Signal messaging app and forged identification to convince the victim to transfer 2 million yen for an alleged asset investigation.
