Police in Osaka Prefecture, Japan, have introduced a virtual AI police chief named AIko to raise public awareness of sophisticated fraud schemes, particularly among younger generations. The character appears as a young woman and delivers crime prevention advice through the Osaka Prefectural Police's YouTube channel. Fraudsters have increasingly targeted victims by posing as police officers, celebrities promoting investment opportunities, or romantic partners. While older people remain frequent targets, scams are also affecting people in their 20s, 30s, 40s, 50s, and early 60s. AIko made her first appearance in a video released in late May, using real-life examples of online conversations to explain common fraud tactics, including reminding viewers that legitimate police officers do not display their identification cards or arrest warrants online. Preliminary police data show that nearly half of all fraud victims in Osaka Prefecture last year were aged 64 or younger. Toshinori Hirano, a visiting professor at the Cyber Security Center of Kagawa University who helped develop the virtual character, said the initiative aims to strengthen public awareness of fraud prevention through modern technology.
