TOKYO, JAPAN / RankWire.AI / – Japan is expanding its response to investment fraud by using artificial intelligence to detect warning signs in consumer complaints. The Consumer Affairs Agency announced the initiative on September 1 as part of a wider anti-fraud package. The system will analyze complaint language, solicitation patterns and similarities with past cases. Officials aim to identify signs of harmful schemes and troubled businesses earlier through data already collected from consumers across the country.
AI complaint analysis joins Japan’s broader response to investment scams and online fraud.
Japan’s PIO-NET consumer database receives about 900,000 consultation records each year. The new system will examine those records for context, key phrases and patterns linked to previous fraud cases. AI analysis will support existing keyword searches rather than replace them. Officials will use the findings to spot recurring solicitation methods and business structures. The system can also identify warning signals across separate complaints that may appear unrelated when viewed individually.
The measures focus on schemes that promise large returns or regular dividends before operators run into financial trouble. Authorities highlighted cases involving overseas investment products, foreign real estate and arrangements tied to deposited goods. Some cases have involved USB devices and other items used in sales structures. Japan also plans to gather information from websites, social media and specialist consultations. The package reflects concern over fraud methods that have become more complex across different consumer channels.

Information produced through the new analysis can support early warnings about specific products, services and solicitation techniques. Consumers may also receive guidance before signing contracts when questions arise about a company or investment offer. Authorities can use the data to begin inquiries and take administrative action when legal grounds exist. Relevant findings may also reach other government bodies, financial institutions and local consumer protection networks to improve information sharing across the existing enforcement system.
Japan will also establish an early warning preparation office to centralize information from several sources. The Consumer Affairs Agency plans to use recent fraud cases in public education and consumer awareness materials. Officials separately warned about secondary scams targeting people who have already suffered investment losses. Reported tactics include demands for additional payments, false claims about government compensation programs and offers to recover earlier losses in exchange for fees or another investment.
Social media investment scams drive heavy losses
Police data show a sharp increase in social media investment fraud during the first half of 2026. The National Police Agency recorded 5,893 cases during that period. Reported losses reached 79.79 billion yen, rising by 44.49 billion yen from a year earlier. Average losses in completed cases were about 13.63 million yen. Banner advertisements ranked as the most common initial contact method among recorded investment fraud cases linked to social media platforms.
Japan has also increased scrutiny of fraudulent investment advertising and impersonation scams online. In August, financial and law enforcement authorities asked major social media operators to strengthen controls against deceptive advertisements. The Financial Services Agency also accepts reports about suspicious investment promotions and related social media posts. The new AI program adds large-scale complaint analysis to those measures. It also links consumer warnings, consultations, investigations and enforcement through information drawn from nationwide complaint records.
