Illegal Online Gambling on the Rise in Japan
Recent surveys by Japan’s National Police Agency reveal a troubling spike in illegal online gambling. With an estimated 3.37 million individuals engaging in these activities and ¥1.2 trillion (approximately $8.07 billion) spent annually, the scale of illicit gambling has caught the government’s urgent attention.
The ease of access afforded by smartphones and digital payment systems has fueled this surge. Despite strict laws banning online gambling in favor of regulated betting like horse and motorboat racing, over 43.5% of players remain unaware that these platforms operate illegally.
Cabinet-Driven Strategy to Combat Online Casinos
Strengthening Law Enforcement
In March 2025, under the leadership of Prime Minister Shigeru Ishiba, the Japanese Cabinet launched a comprehensive crackdown plan targeting illegal gambling operators and affiliates. Key measures include:
- Criminalizing payment collection agencies assisting illegal casinos.
- Restricting business advertising and promotion of online casino sites.
- Launching widespread social media campaigns to warn users that online gambling is illegal.
Proposed Legislative Action
A bipartisan coalition in the Japanese government has drafted a new bill explicitly banning the operation, promotion, and advertisement of online casinos. Anticipated to pass during the current Diet session, the legislation reflects broad political alignment on the need for stricter gambling controls.
Additionally, this legislation seeks to close loopholes by banning referral systems and affiliates. These entities earn commissions by directing users to illegal gambling platforms.
Additional Technical Measures Considered
The Ministry of Internal Affairs and Communications is exploring technical solutions to prevent user access to such platforms. One of the proposed solutions includes a site-blocking system aimed at shutting down illegal online casino domains, but broader discussions are ongoing to iron out implementation challenges.
Key Statistics and Enforcement Milestones
| Statistic | Value |
|---|---|
| Illegal Online Gambling Users | 3.37 million |
| Active Annual Users | 1.97 million |
| Annual Expenditure | ¥1.2 trillion (approx. $8.07 billion) |
| Record Arrests in 2024 | 279 (160% increase YoY) |
| Users Unaware Gambling is Illegal | 43.5% |
Social Impacts and Government Concerns
The growing prevalence of illegal online casinos has serious societal implications. Advocacy groups highlight rising debt levels and the increase in risky behaviors such as involvement in illicit part-time employment, also known as “dark jobs.”
Yoshitaka Ito, the minister overseeing anti-gambling measures, emphasized the urgent need to safeguard vulnerable populations through a combination of stricter regulations and public education campaigns.
Conclusion: A Firm Stand Against Illegal Gambling

Japan is taking decisive action to restrict illegal gambling and mitigate its impact on society. The combination of enhanced law enforcement, public awareness campaigns, and pending legislation represents a critical step forward in addressing addiction and financial loss among citizens. As these measures unfold, their success will likely serve as a case study for other nations grappling with similar issues.
