Japan's new AI police: How AIko is protecting millions from $2 billion online scams before it's too late
Japan's battle against online fraud has taken an unusual turn with the arrival of a virtual police chief designed not to patrol streets but to appear on screens. While governments around the world are experimenting with artificial intelligence in public services, Japanese authorities are using it in a very public way: speaking directly to potential scam victims before criminals can reach them. The digital character, known as AIko, represents a shift in how police communicate with younger audiences who spend much of their time online rather than engaging with traditional public awareness campaigns.
Her launch also reflects a wider challenge facing Japan, where financial fraud has become increasingly sophisticated, crossing borders and targeting people of all ages. At the same time, the government is embracing AI inside its own institutions, hoping the technology can improve both public safety and administrative efficiency.
AIko: Japan's virtual police chief leading the fight against online scams
Instead of standing behind a podium or appearing at a press conference, Osaka Prefectural Police 's newest crime prevention figure appears on YouTube.
The virtual character, called AIko, combines the initials of artificial intelligence with the common Japanese feminine name ending "ko". Presented as a police chief, she speaks with a calm, approachable voice while explaining how modern scams work and why many victims fail to recognise warning signs until it is too late.
Her videos focus on practical situations rather than broad advice. Viewers are shown examples of fake conversations used by fraudsters, helping them recognise methods commonly employed by criminals. One message is particularly straightforward: genuine police officers do not display identification cards or arrest warrants through online messages or video calls.
As reported by the South China Morning Post (SCMP), the project was created by Toshinori Hirano, a visiting professor at Kagawa University's Cyber Security Centre, who previously worked with Osaka police on cybercrime issues. He aimed to use familiar digital technology to improve public awareness in a format that people are more likely to watch than conventional safety campaigns.
Why Japan is shifting its fraud warnings towards younger audiences
For years, fraud prevention efforts in Japan often focused on protecting older residents, who have traditionally been considered the most vulnerable to financial scams. Recent figures suggest the picture has changed.
Police data from Osaka indicate that people under the age of 65 now account for nearly half of reported fraud victims. That trend has encouraged authorities to rethink where and how they communicate. Instead of relying primarily on television broadcasts, printed leaflets or community meetings, they are increasingly turning to online platforms where younger audiences already spend their time.
YouTube offers a setting that feels less formal while allowing police messages to circulate more widely through sharing and recommendations. Officials hope that presenting information through an animated digital figure makes the content easier to approach without reducing the seriousness of the subject.
The scam tactics behind Japan's record financial losses
Japan recorded more than US$2 billion in losses from investment scams, romance fraud and other confidence schemes linked to social media last year, the highest figure on record.
Many cases begin with what appears to be an ordinary online conversation. Victims may believe they are speaking to a police officer investigating financial crime, a celebrity promoting an investment opportunity or someone developing a romantic relationship over time. Once trust has been established, requests for money or investments often follow.
Criminals continue to refine their techniques, making scams harder to identify even for people who consider themselves digitally aware. Authorities say the growing sophistication of these operations explains why prevention campaigns now focus on education as much as criminal investigation.
How Japan plans to modernise government with AI
The use of AI is not limited to public awareness campaigns. Japan's government is preparing a much broader rollout of generative AI tools across the civil service, reflecting a wider effort to modernise administrative work that has long been criticised for being slow and heavily paper-based.
At the centre of the programme is Gennai, an internally developed AI platform created by the government's Digital Agency. The system is designed for use within a secure government environment, allowing officials to generate documents, transcribe meetings, translate material, conduct legal research and prepare responses for parliamentary business without relying on publicly available AI services.
Because the platform operates inside protected government systems, officials believe it reduces the risk of confidential information leaving official networks while still providing the productivity gains associated with generative AI.

The government plans to make Gennai available to around 180,000 employees working across 39 national agencies following a large pilot programme.
