- Japan’s parliament passed a law on June 18, 2025, banning ads for offshore online casinos, targeting 3.37M residents betting ¥1.24T ($8.6B) yearly.
- The law, effective autumn 2025, fines violators ¥500,000 ($3,500) and urges eight regions to block access; it aims to protect the $1.2B legal market.
- Offshore sites took ¥6.45T ($45B) in 2024; legal betting like lotteries is safe as Japan preps for Osaka’s 2030 casino launch.
Why Japan Cracked Down on Offshore Gambling
The new law targets a surge in illegal online gambling, with 3.37 million Japanese residents betting ¥1.24 trillion ($8.6 billion) annually on offshore sites, despite gambling being illegal outside state-sanctioned lotteries and races.
High-profile cases, like J-Pop star Shion Tsurubo’s 2025 charges for online betting, sparked public outcry, pushing lawmakers to act.
The $1.2 billion legal gambling market, limited to horse, bicycle, boat, and motorcycle races, faces threats from unregulated platforms, prompting Japan to protect its citizens and future casino projects like MGM’s $9.4 billion Osaka resort, set for 2030.
You can see the urgency: offshore sites are draining potential revenue and fueling addiction.

Details of the New Law
The revised Basic Act on Measures Against Gambling Addiction bans ads and promotions for offshore online casinos, criminalizing the operation of such sites or apps in Japan.
Violators face fines up to ¥500,000 ($3,500), with repeat offenders risking three years in prison. The law urges internet providers and social media to remove gambling content and requires public awareness campaigns to clarify that betting on overseas sites is illegal.
Japan also asked eight regions—Canada, Costa Rica, Georgia, Malta, Anjouan Island, Curacao, Isle of Man, and Gibraltar—to block Japanese access to their licensed casinos, with 70% of Japanese-language sites based in Curacao. You might notice the scope: this is a multi-front attack on digital gambling.
Impact on Japan’s Gambling Industry
Japan’s legal gambling, generating ¥2.6 billion from 3,600 bettors in 2024, is tightly controlled, but offshore sites siphoned ¥6.45 trillion ($45 billion) in sports bets alone last year.
The law aims to redirect bets to regulated options, protecting the upcoming Osaka casino and state revenue. For you, this means fewer ads for risky offshore platforms, but access to illegal sites via VPNs remains a challenge.
X posts cheer the crackdown but note enforcement hurdles, with 90 billion ($628.5 million) in gambling funds seized in 2025. With nations like the U.S. tolerating offshore play, Japan’s strict stance stands out. You might wonder: will this kill illegal betting or just push it underground?
What’s Next for Japan’s Gambling Rules
The law takes effect by autumn 2025, with Japan planning to revisit its requests to the eight regions post-enactment. Police will intensify enforcement, building on 2025’s arrests of nine people managing ¥90 billion in gambling accounts.
The government eyes payment processors to choke off funds, similar to Brazil’s 2025 crackdown. You might be curious about safe betting: stick to legal lotteries or race betting until Osaka’s casino opens.
As Japan guards its $1.2 billion market, the law signals a bold move to curb addiction and protect economic gains from regulated gambling.
