In 2025, Japan reported a staggering 4,747 cases of fraudulent remittances related to internet banking, marking an 8.7% increase from the previous year, and amounting to a total financial loss of approximately 10.397 billion yen, which is a substantial 19.6% increase year-over-year. This marks the first time the loss due to such scams has exceeded 10 billion yen, prompting concern among law enforcement agencies and financial institutions alike. The rise in these cases underscores the growing vulnerability of consumers and businesses to online fraud.

The majority of these fraudulent activities are attributed to phishing, where victims are lured to fake websites designed to steal their banking credentials such as IDs and passwords. Criminal organizations exploit this information to hijack victims’ accounts and execute unauthorized remittances. Phishing tactics usually involve disguising as legitimate companies or services, sending emails or SMS messages with links to counterfeit websites that closely mimic the real ones, which increases the likelihood of obtaining sensitive information from unsuspecting users.

The police are particularly concerned about the efficacy of these scams, which have been augmented by the misuse of generative AI technology, allowing for the creation of highly convincing emails and websites. This evolution in tactics signals a critical challenge in cyber security, especially in light of the reported increase in corporate casualties. Stakeholders are urged to adopt stricter security measures and to educate users about recognizing such scams to mitigate further financial losses.
