Japan has introduced an artificial intelligence-powered “police chief” named Aiko as part of a nationwide campaign to combat a sharp rise in fraud that has cost victims more than $2 billion in recent years. Launched by the Osaka Prefectural Police, the initiative aims to raise public awareness about increasingly sophisticated scams targeting people of all age groups.
Aiko is an AI-generated avatar designed to educate the public about common fraud methods, including investment scams, romance scams and impersonation fraud involving police officers, celebrities and other trusted individuals. The digital character appears in videos on the police department’s official YouTube channel, explaining how fraudsters manipulate victims and highlighting warning signs to help people avoid scams.
According to authorities, the initiative comes as cyber-enabled fraud continues to rise, with criminals increasingly relying on social engineering techniques instead of technical hacking. Officials said these scams are no longer limited to older adults and are now affecting younger people through online platforms, messaging apps and fake investment schemes.
Introduced in late May, Aiko demonstrates real-world scam scenarios through staged conversations and step-by-step explanations of how digital fraud operates. One of the campaign’s key priorities is to counter impersonation scams, where criminals pretend to be police officers or government officials through video calls or messaging platforms. Aiko reminds viewers that legitimate police officers will never ask for money or sensitive personal information through such channels.
Officials said the campaign reflects Japan’s growing concern over the financial and psychological impact of increasingly organised and technology-driven fraud networks. Many of these scams rely on trust-building tactics and fake investment platforms that display fabricated profits to convince victims to invest larger amounts.
The Osaka Prefectural Police believe AI-powered communication tools such as Aiko can make fraud awareness more engaging while improving public understanding of emerging scam patterns and encouraging early reporting of suspicious activity. The department plans to continue expanding Aiko’s content to address new fraud techniques as they emerge.
Experts say the initiative reflects a broader global trend of law enforcement agencies using artificial intelligence not only for investigations but also for cybercrime awareness and prevention.
