Lawmakers Fast-Track Bill to Crack Down on Overseas Casino Sites
Japan is preparing sweeping legislative action to clamp down on the rampant use of illegal online gambling platforms, as data reveals billions of yen flowing to overseas betting sites each year. A new bill targeting online casinos is expected to be submitted to parliament this month, with bipartisan backing from both ruling and opposition parties.
The legislative push follows mounting concern over a booming illicit gambling market that saw an estimated ¥6.45 trillion (about $44 billion) in wagers last year—despite Japan’s strict ban on online casinos.
Online Betting Explodes, Fueled by Social Media and Easy Access
A recent report from the Council for Sports Ecosystem Promotion highlights the growing prevalence of illegal betting. Of the trillions gambled, ¥5.43 trillion went to international sports betting, while ¥1.02 trillion was staked on Japanese sporting events—baseball being the most popular with ¥528.1 billion in bets.
In contrast, Japan’s legal sports lotteries brought in just ¥133.6 billion in 2024, a fraction of the illegal total.
This surge is primarily attributed to Japanese-language gambling sites, aggressive social media advertising, and seamless payment options, including bank transfers and credit cards. A National Police Agency survey found 3.37 million users had engaged in online gambling, with nearly half unaware the activity was illegal.
Arrests related to online gambling also hit a record high of 279 in 2024—a 160% jump from the previous year.
Proposed Law to Ban Online Casinos and Their Promotion
The upcoming bill will amend Japan’s basic law on gambling addiction countermeasures, first enacted in 2018. Central to the proposal is a ban on operating online casinos and a prohibition on any form of promotion—particularly on social media—that links users to gambling sites.
Lawmakers want to eliminate legal gray areas, making it easier for authorities and internet providers to remove gambling-related ads and content. The Internal Affairs and Communications Ministry is also weighing the use of access blocks to shut off Japanese users from casino sites entirely.
Although Japan’s Penal Code already prohibits gambling—even on platforms licensed abroad—the current law lacks teeth when it comes to enforcement, especially against offshore operators.
Public Awareness and Cross-Border Enforcement Still a Hurdle
While the bill includes provisions for nationwide awareness campaigns, it doesn’t introduce new penalties. That omission has sparked concerns over whether the reforms will be enough to slow the online gambling boom.
The government is also preparing to work more closely with international organizations to tackle issues like match-fixing and sports integrity risks. But with limited jurisdiction over foreign-based platforms, and enforcement hampered by technical challenges, Japan’s efforts face an uphill climb.
Meanwhile, legal gambling options remain limited. The country’s first integrated resort, MGM Osaka, is set to open in 2030—marking a slow and cautious path toward regulated casino gaming.
