- On June 2, 2025, Japan’s House of Representatives passed a bill banning illegal online casino operations and promotions, targeting a ¥1.24 trillion ($8.7B) illicit market.
- The bill, amending the 2018 addiction law, bans ads and social media links to offshore casinos but lacks penalties, with passage expected by June 22, 2025.
- With 3.37 million users, Japan’s crackdown may limit illegal betting but risks pushing players to unregulated sites, as legal casino resorts prepare to launch.
Why the Bill Was Passed
On June 2, 2025, the House of Representatives, Japan’s lower parliamentary chamber, passed a bill to tighten regulations against illegal online casinos, driven by growing concerns over gambling addiction and financial crime.
A National Police Agency (NPA) survey from March 2025 estimated 3.37 million Japanese residents wagered ¥1.24 trillion ($8.7 billion) annually on offshore platforms, despite online gambling being illegal under the Penal Code.
Many users, unaware of the law, are lured by social media ads and Japanese-language sites. You can see the urgency: with one in five young people prioritizing betting over bills, the government aims to curb this $44.2 billion shadow market, especially as Japan prepares for its first casino resort in Osaka by 2030.
Details of the Legislation
The bill amends the 2018 Basic Law on Countermeasures Against Gambling Addiction, prohibiting the establishment and operation of online casino platforms and banning ads or social media promotions that guide users to these sites.
It empowers authorities to order communication providers to remove such content and mandates public awareness campaigns to clarify that online gambling is illegal. Notably, the bill lacks specific penalties for violators, which critics argue may limit enforcement.
Supported by a rare coalition of the Liberal Democratic Party, Komeito, and opposition parties like the Constitutional Democratic Party, it’s expected to pass the House of Councillors before the Diet session ends on June 22, 2025.
You might notice the challenge: while the bill targets operators and promoters, offshore platforms remain hard to police.

Impact on Japan’s Gambling Industry
Japan’s legal gambling market is confined to state-run lotteries and race betting, generating ¥133.6 billion in 2024, dwarfed by the ¥6.45 trillion ($44 billion) spent on illegal offshore sites, with soccer bets alone at ¥2.9 trillion.
This bill could deter local promoters and reduce access to illicit platforms, especially as the Internal Affairs Ministry explores website blocking.
This might mean safer, regulated options as Japan expands legal gambling with casino resorts, but strict enforcement risks pushing bettors to savvier offshore sites. The industry faces pressure to balance addiction prevention with tourism goals, as posts on X highlight public skepticism about allowing land-based casinos while banning online ones.
The bill’s passage may also accelerate ad restrictions, impacting influencers and affiliate marketers.
What’s Next for Japan’s Gambling Crackdown
The bill now heads to the House of Councillors, with strong bipartisan support suggesting enactment by late June 2025. The government plans public campaigns and technical measures, like site blocking, to curb access, though experts warn enforcement will be tough without penalties.
A proposed bill to penalize influencers with fines up to ¥500,000 ($3,348) or jail time could follow. You might wonder how this affects your betting: stick to legal options like horse racing to avoid risks, as police intensify probes—279 arrests were made in 2024, up 160% from 2023.
With Japan’s first MGM Osaka resort looming, the focus on addiction may reshape regulations, but the fight against offshore casinos will test the country’s resolve.
