Japan Charts Four-Stage Plan to Block Unlicensed Casino Sites

From Passive to Proactive: Tokyo’s Digital Turning Point

Until now, Japanese authorities have only had the green light to block websites hosting child pornography. Even when it came to pirated manga and illegal streaming, officials were reluctant to intervene due to privacy and constitutional limitations.

But growing concern around unregulated gambling and addiction has prompted urgency. A panel of experts has been meeting since April to assess whether stricter measures should be implemented - legally and technically. And they’ve come up with a structured approach.

The Four-Stage Blocking Framework

The proposal recommends a careful, step-by-step approach to implementing website blocks, ensuring all legal boxes are ticked before any action is taken.

It’s a cautious but deliberate path, designed to minimise backlash while reinforcing national regulations.

Legal Backing in Motion

Alongside the proposed website restrictions, lawmakers are close to approving amendments to the Basic Law for Countermeasures Against Gambling and Other Addictions. These changes aim to:

• Criminalise the operation, marketing, and use of unlicensed online gambling services.
• Introduce harsher penalties for offenders.
• Empower social media platforms to remove gambling-related content.
• Legitimise geoblocking requests to overseas operators.
• Allow platforms to create stricter user terms and enforcement rules.

With legislative backing, digital platforms will be able to respond more confidently and swiftly to state-level anti-gambling measures.

A Global Warning and DNS Tactics

Japanese police aren’t waiting around. They’ve already reached out to seven foreign governments via the Ministry of Foreign Affairs, urging them to push operators in their jurisdictions to stop targeting Japanese players.

The government is also eyeing DNS blocking, a tactic already used in Japan to restrict access to illegal content. DNS (Domain Name System) filtering stops browsers from matching specific domain names with their corresponding IP addresses, effectively making sites vanish from view.

The ministry suggests this approach would allow internet service providers to take a more active role in enforcing the upcoming measures.

New Era in Japan's iGaming Regulations

Japan’s four-stage website blocking proposal marks a turning point in its digital governance. With legislation, technology, and diplomacy working in tandem, Tokyo is taking deliberate steps toward closing the loopholes exploited by offshore gambling operators.

Whether through legal reform, DNS filtering, or cross-border cooperation, the message is clear: Japan is tightening its grip and the days of unchecked access may soon be over.
