Japanese AI police chief takes on $2 billion scam epidemic

The Osaka police force is using an AI avatar of a police chief to help raise awareness of an online fraud outbreak that cost victims around $2 billion in 2025.

Japan’s Osaka police are using an AI avatar police chief named Aiko to raise awareness about online scams that caused around $2 billion in losses in 2025.
-
Scammers are using more advanced tactics like AI-generated voices, fake police identities, forged warrants, and video calls to trick victims into sending money.
-
Scam networks in Southeast Asia are expanding, with authorities responding through crackdowns, stricter laws, and international enforcement actions.
Represented strictly as an avatar with no real-life governance powers, Aiko is designed to appeal to social media users, aiming to raise awareness of police impersonation by scammers.
Criminal networks are becoming increasingly more sophisticated in Southeast Asia, targeting younger users too, as roughly half of the victims are under the age of 65, as reported by the South China Morning Post.
The name AIko combines the well-known abbreviation for artificial intelligence, AI, with the “ko” suffix commonly used with female names in Japan.
The brains behind the creation was Professor of Cybersecurity Toshinori Hishano, who had previously consulted with the Osaka police before helping them deploy Aiko.
Hishano told Kyodo News that the aim was to "heighten crime prevention awareness by utilizing technology."
Fake police impersonation and other scams
“No police officers show their IDs and arrest warrants online,” explains Aiko in the video, in relation to the surge of incidents involving impersonation of police officers during convincing video calls.
Fake badges, fabricated arrest warrants, and official-looking documents are used to pressure victims into transferring money, with video calls increasing the believability. Investment scams and parasocial celebrity interactions are also common.
AI-generated identities and cloned voices are often used in the deceptive process. Upon hooking a victim with AI-generated content, scammers use bait-and-switch tactics to redirect the activity to encrypted platforms such as Telegram or Signal.
There has been a broader targeting of online scam syndicates in Southeast Asia, with efforts to crack down on such activity, including Cambodia's passing of strict legislation in April.
And last year, the US Department of Justice seized billions worth of Bitcoin from a shady consortium based in Cambodia, as defrauding operations in the region continue to evolve.
