Japan Considers ISP Blocking to Combat Illegal Offshore Online Casinos

Japan is intensifying its campaign against illegal offshore gambling activities. A government expert panel has indicated that website blocking remains a viable option to disrupt unlicensed online casinos. For a long time, such measures were considered controversial due to potential conflicts with constitutional protections regarding the secrecy of communications. However, the persistence of the illegal market is forcing officials to rethink their strategy. Authorities are now preparing to evaluate less intrusive measures before deciding whether to implement full-scale digital barriers.

A recent report from the Ministry of Internal Affairs and Communications detailed the current stance of the administration. Policymakers are attempting to balance data privacy with the urgent need for consumer protection. Currently, the Japanese government is testing alternative enforcement methods, such as banning affiliate links on social media platform and requesting cooperation from foreign jurisdictions where these operators are based. The effectiveness of these steps will be reviewed as early as this autumn.

Numbers and facts

The move follows a formal public consultation period held throughout May and June. During this time, 236 organizations, companies, and individuals submitted their opinions on a draft report concerning website blocking. The majority of these respondents expressed support for the measure, arguing that it is the most effective way to prevent younger people from accessing harmful content. Critics, however, pointed out that blocking requires telecommunications providers to monitor web traffic, which could infringe on user privacy.

The timeline for the next steps is clear. By fall, the government plans to assess the impact of current measures. Japan is specifically targeting the infrastructure of illegal gambling by making it unlawful for social media posts to redirect users to unauthorized casino platforms. If these measures do not result in a significant decrease in illegal traffic, the expert panel suggested that more drastic technical blocks should be on the table.

Background

The legal debate centered on the Japanese Constitution, which protects the secrecy of any means of communication. Blocking a website typically involves Deep Packet Inspection or DNS filtering, both of which require an intermediary to look at where a user is going. Some members of the expert panel remain skeptical, advocating for blocking only as a last resort. Others, however, believe that the social harm caused by unregulated gambling outweighs these privacy concerns.

The Japanese authorities are also looking into international cooperation. By communicating with foreign regulators, they hope to shut down access to Japanese users at the source. This multi-layered approach reflects the complexity of modern digital enforcement where local laws often clash with the borderless nature of the internet.

Why it matters for German players

For players in Germany, the Japanese situation serves as a reminder of the global trend towards strict regulation. Since the 2021 State Treaty on Gambling (GlüStV 2021) came into effect, the German Joint Gambling Authority of the States (GGL) has also been exploring ways to block illegal providers. In Germany, players are legally protected only when using sites on the official GGL Whitelist. These sites enforce a 1,000 Euro monthly deposit limit across all platforms, tracked by the LUGAS system. Engaging with offshore sites, such as those licensed in Curacao or by the MGA, carries significant risks, as these operators do not participate in the national OASIS lockout system. Furthermore, German law stipulates a 1 Euro maximum bet per spin and a mandatory five-second delay for virtual slots, rules that illegal operators often bypass to attract customers.

What it means for GGL-licensed casinos

For casinos holding a German GGL license, the crackdown on illegal offshore sites is essential for maintaining a fair market. Regulated operators incur significant costs for tax compliance and player safety measures, while illegal competitors operate with much lower overheads. If a major market like Japan moves toward website blocking, it signals a tightening of the global net around unregulated operators. In Germany, the GGL has already begun targeting payment processors to cut off the financial lifelines of black market sites. Effective enforcement against illegal actors ensures that the legal industry, which adheres to strict player protection standards, can thrive without being undercut by offshore entities. The developments in Japan echo the sentiment of German regulators: protecting the legal market is the only way to ensure sustainable player safety.
