Japanese authorities have uncovered more than 3,000 illegal gambling websites and social media posts targeting domestic players, but are finding it nearly impossible to get them taken down. The Internet Hotline Center, which operates under the National Police Agency, flagged the pages between September and December last year. The removal process? Going nowhere fast.

Takedown Requests Fall on Deaf Ears

The IHC’s approach is straightforward enough: identify illegal content, issue takedown requests, wait for compliance. The problem is that hardly anyone’s listening. Of roughly 300 cases involving Japan-based operators and influencers, mostly affiliate marketers earning commissions from overseas casinos, fewer than 40% have complied with removal notices.

The situation gets worse with international operators. Police identified nearly 3,000 cases originating abroad, including 464 websites and over 2,500 social media posts. They’ve sent takedown requests to more than 2,700 operators.

The compliance rate? Under 20%. Just 500 have bothered responding.

The National Police Agency points to a fundamental issue here: many countries where these operators are based simply don’t regulate online casinos the way Japan does. Without matching legal frameworks, there’s no leverage to force compliance. Japanese law is clear enough. Operating, advertising, and even accessing offshore casinos from Japanese territory are all criminal offences. Enforcing that beyond Japan’s borders is another matter entirely.

MGM Osaka Moves Forward Despite Questions

While authorities battle illegal offshore operations, Japan is preparing to launch its own legal gambling sector through integrated resorts. The MGM Osaka project in Osaka Bay remains the only IR to gain government approval so far, with a planned 2030 opening. MGM and Japanese partner Orix are banking on 20 million visitors annually once doors open.

Recent analysis suggests the economic windfall might not pan out as planned. Labor shortages across Japan’s tourism sector could hamper operations. Plus, diplomatic tensions with China add another complication. Beijing recently banned group tours to Japan following Prime Minister Sanae Takaichi’s comments about Taiwan being an existential concern for Japanese security.

Osaka officials remain bullish on the project’s potential. Mayor Hideyuki Yokoyama told reporters the IR would serve as a catalyst for the broader Osaka-Kansai economic zone. The city and prefecture have allocated 124.52 million yen, roughly $781,000, in their 2026 budget for IR promotion. Plans include station advertising throughout the prefecture, online campaigns, and promotional videos on taxi screens across Osaka.

The Enforcement Gap Widens

The contrast couldn’t be sharper. Japan is spending close to a million dollars promoting a legal casino that won’t open for four years, while struggling to remove thousands of illegal gambling sites already operating today. The enforcement gap reveals a broader challenge facing regulators worldwide: territorial laws versus borderless digital markets.

For now, those 3,000 flagged pages largely remain online. Without international cooperation or technical blocking measures, Japanese authorities are left sending polite removal requests into the void. The IHC will keep flagging content, operators will keep ignoring requests, and the cycle continues.

It’s a familiar story in digital enforcement, made sharper by Japan’s particularly strict stance on gambling outside sanctioned resorts.

When MGM Osaka finally opens in 2030, it will compete not just with other Asian gaming destinations, but with the same offshore sites that Japanese police can’t seem to shut down today.
