The National Police Agency (NPA) of Japan has released its comprehensive enforcement statistics for the 2025 fiscal year, revealing an aggressive and successful campaign against the country’s unauthorized digital gambling market.
According to the official NPA report (published April 2026), Japanese authorities logged a 35% year-on-year increase in arrests related to illegal online gambling. The data underscores a strategic pivot by Japanese law enforcement: moving beyond targeting individual players to dismantling the financial and technical infrastructure that sustains offshore grey market operators.
Dismantling the Payment Surrogate Networks
The most significant shift in the 2025 data is the focus on payment surrogate services, specialised agencies that facilitate Yen-based transactions between local players and offshore sites.
- The Financial Net: For the first time, the NPA highlighted the successful shutdown of three major illicit underground banks that processed an estimated ¥25 billion ($165 million) in gambling-related transfers.
- Coordinated Raids: Enforcement wasn’t limited to digital tracking. The report notes dozens of physical raids on internet casinos and physical shopfronts where patrons use offshore websites, resulting in the seizure of hundreds of terminals.
- Public Awareness: The NPA, in collaboration with the Consumer Affairs Agency, has intensified its public messaging, reminding citizens that even accessing licensed offshore sites from within Japan constitutes a crime under the Penal Code.
A Global Trend: Regulators Targeting the Rails
Japan’s aggressive stance on illicit payment processors mirrors a broader global movement where regulators are attacking the financial rails of the gambling industry to enforce local laws.
- The Digital Pincer: This strategy is highly visible in Brazil, where the Ministry of Justice recently notified Google and Apple to purge unlicensed betting apps from their stores.
- Omnibus Enforcement: It also echoes the Philippines’ unified SOP for its POGO ban, which synchronises police work with financial intelligence to ensure illegal operators cannot simply rebrand and reappear.
- Predictive Oversight: While Japan relies on traditional enforcement, other regions are turning to technology, such as the ACMA’s focus on AI-driven oversight in Australia, to identify and block prohibited gambling traffic in real-time.
Protecting the Future of Integrated Resorts
Analysts suggest that the NPA’s current intensity is a pre-emptive strike to protect the integrity of Japan’s upcoming Integrated Resorts (IR). With the first legal casino projects in Osaka moving forward, the government is keen to ensure that the domestic market is not cannibalised by unregulated offshore entities that pay no taxes and offer no responsible gaming protections.
The report concludes that the visibility gap between offshore activity and local regulation is narrowing. For B2B providers and affiliates, the message from Tokyo is clear: Japan’s historical quiet tolerance for grey-market activity is officially over.
As law enforcement continues to refine its follow-the-money tactics, any platform facilitating Yen transactions without a specific domestic mandate faces an unprecedented level of judicial risk in 2026 and beyond.
