TOKYO, JAPAN / RankWire.AI / – Japan is advancing its efforts to combat investment scams by introducing a new system that employs artificial intelligence to identify warning signals at an earlier stage. The Consumer Affairs Agency revealed this initiative on September 1, explaining that it will scrutinize consumer complaints for language patterns and indicators associated with fraudulent schemes and failing companies. The report states that AI will serve as a supplement to current keyword search methods, enabling earlier detection, investigation, and enforcement actions when complaint data suggest significant risks.
This AI tool will analyze approximately 900,000 consultation records annually within PIO-NET, Japan’s national database of consumer complaints. It will compare new complaints against historical contexts and key phrases derived from previous cases, searching for solicitation tactics, business structures, and early signs of financial instability. Additionally, it can identify common patterns across multiple operators, even if a complaint does not explicitly report a concrete financial loss.
The new framework targets schemes that guarantee high returns or dividends and gather funds from large numbers of consumers before ultimately failing. Authorities highlighted cases involving overseas financial products, foreign real estate investments, and arrangements related to deposited goods, such as USB devices. Japan also intends to increase data collection from websites, social media platforms, and specialized consultations. The government emphasized that fraud techniques and money laundering methods have become increasingly diverse and sophisticated.
Enhanced AI analysis expands the scope of early warning capabilities
As part of this initiative, officials will leverage AI findings to issue early alerts concerning specific methods, products, or services, thereby supporting pre-contract consultations for consumers who raise concerns about a company’s legitimacy. When cases warrant further action, authorities can initiate investigations and apply administrative measures following existing legal frameworks. Japan also plans to share relevant intelligence more promptly with government agencies, financial institutions, and local consumer protection organizations to facilitate coordinated responses.
The plan also proposes establishing an early warning preparation office responsible for gathering and analyzing signals from multiple information channels. The Consumer Affairs Agency intends to promote public education using updated fraud cases and practical training materials. Separately, on September 1, authorities issued warnings about secondary scams targeting individuals who have already suffered financial losses, including demands for additional payments, claims related to government reimbursement programs, and offers to recover previous investments for a fee.
Investigation reveals sharp rise in social media-driven investment fraud losses
Data from law enforcement authorities illustrate the extent of investment fraud via social media across Japan, with the National Police Agency reporting 5,893 cases in the first half of 2026. Reported damages amounted to 79.79 billion yen, an increase of 44.49 billion yen compared to the same period in the previous year. The average loss per completed case was approximately 13.63 million yen. Banner-style advertisements emerged as the most common initial contact method in those fraud cases.
In response, Japan has intensified measures against deceptive investment advertisements on social media platforms. In August, financial and law enforcement agencies urged major platform operators to enhance controls against impersonation scam ads. The Financial Services Agency also accepts reports concerning suspicious investment advertisements and social media posts. The new AI-based consumer complaint system adds large-scale analysis capabilities to these efforts, linking warning signals with ongoing investigations, consumer support, and enforcement channels.
