Japan has reported a sharp rise in illegal online gambling cases for 2025, reflecting growing scrutiny and regulatory action. Read on for essential details and implications for the gambling sector.
Key Takeaways
- Illegal online gambling cases in Japan reached a record high in 2025.
- Affiliates and payment agents played a notable role in promoting and facilitating these activities.
- New legislation aims to strengthen enforcement and address gambling addiction.
Surge in Detected Illegal Online Gambling Cases
Record Numbers in 2025
According to data released by Japan’s National Police Agency (NPA), authorities identified 158 cases of illegal online gambling in 2025, marking an increase of 103 cases compared to the previous year. This rise follows a series of incidents involving athletes and public figures, which contributed to greater public awareness and reporting of such activities.
Role of Affiliates and Payment Agents
The NPA data highlighted the involvement of 221 individuals in these cases, including 196 gamblers and 25 operators. Operators comprised payment agents who managed bets and payouts for fees, as well as affiliates who promoted online casino sites through social media channels. These findings underscore the ongoing challenges posed by affiliate marketing in the gambling industry, particularly when it comes to compliance with local regulations.
Legal Context and Enforcement
While many online casino operators are licensed in other jurisdictions, Japanese law prohibits residents from accessing and betting on these platforms, even via smartphones or other digital devices. The NPA’s recent enforcement actions reflect this legal stance. In total, when including cases involving physical terminals at retail locations, authorities recorded 165 online gambling incidents involving 317 people.
Regulatory Response and Legislative Updates
New Measures to Address Gambling Addiction
In response to the growing number of cases, Japan enacted revised legislation in the previous year targeting gambling addiction. The updated law bans access to online casino sites and authorizes authorities to request the removal of related online content. NPA Commissioner General Yoshinobu Kusunoki emphasized the need for continued vigilance and stronger measures against illegal operators, noting that some sites remain accessible from within Japan.
Broader Enforcement Actions
Beyond online gambling, police initiated investigations into 71 cases related to host clubs in 2025, a decrease of 10 from the prior year. These cases involved 143 individuals, down by 64, and typically centered on host clubs pressuring female customers into prostitution or other work to settle debts. Administrative actions under amusement and entertainment business regulations totaled 251, including five license revocations.
Human Trafficking Cases
Authorities also addressed 142 human trafficking cases in 2025, up by 46 from the previous year, involving 78 individuals. One case involved the arrest of a massage parlor operator in Tokyo for allegedly forcing a 12-year-old Thai girl into sex work.
Implications for the Gambling and Affiliate Marketing Industry
The increase in detected illegal online gambling cases and the involvement of affiliates highlight the ongoing need for compliance and responsible marketing practices within the gambling sector. The updated legal framework signals a more proactive approach by Japanese authorities in curbing illegal gambling and related activities, which is likely to impact both operators and affiliates targeting the Japanese market.

I remember the first time I saw Kai Tak, Hong Kong’s gambling city, I thought I was in a fairy tale. All the lights blinking, the music and the monumental buildings, what 9-year-old wouldn’t think they’ve come to a magical place? It was my father who brought me, dragging me along and when inside I was hit by the smell of frying duck. As soon as I hit 21 I returned to Kai Tak, A bit nervous to see if my mind had embellished the memory, but it hadn’t. Kai Tak was still a magical place. I decided I wanted to spend as much time as I could at this place, so I did.
