Understanding the Smartphone Competition Law

On December 18, 2025, Japan enacted the Smartphone Software Competition Promotion Act, commonly known as the "Smartphone Competition Law." This groundbreaking legislation aims to address market monopolization by tech giants like Apple and Google, creating a more competitive and fair marketplace for mobile applications.

For years, the distribution and monetization of smartphone apps have been dominated by Apple and Google. Developers faced high commission fees with limited alternatives, while users had restricted choices in how they interacted with mobile services. The new law seeks to fundamentally reshape this landscape.

Three Major Changes Coming to Google Play

1. External Website Redirects from Within Apps

The most significant change allows app developers to redirect users from within their apps to external websites for purchases. Previously, developers were largely prohibited from circumventing in-app billing systems to promote direct payments on their own websites.

Google has introduced a new "participation program" that provides registered developers with implementation APIs. However, using this program will incur fees. While Google maintains that "fees are permissible under Fair Trade Commission rules and guidelines," specific commission rates were scheduled to be announced on the day of implementation.

This change is expected to enable developers to accept payments with lower commission rates than the traditional Google Play billing system. For example, when purchasing items in a gaming app, developers can now guide users to their official website to complete the transaction there.

2. Browser and Search Engine "Choice Screen"

Following iOS, Android devices will now feature a "choice screen" for browsers and search engines. During initial smartphone setup, users will be presented with a selection screen to choose their default search engine and browser.

Five options each for browsers and search engines will be displayed in random order. This allows users to consciously choose alternatives to Google Chrome and Google Search. This feature has been rolling out gradually since December 2 for smartphones running Android 15 or later.

3. Expanded Third-Party Payment Services for Gaming Apps

Game developers will gain the ability to offer third-party payment services for in-app content purchases without requiring users to leave the app.

Since 2022, this functionality has been available in Japan for non-gaming apps. With the enforcement of the Smartphone Competition Law, the scope expands to include gaming applications. This enables users to select from multiple payment methods without exiting the app.

Benefits for Users and Developers

For Users

  • Increased Choice: Freedom to select from various browsers, search engines, and payment methods
  • Potential Price Reductions: If developer commission burdens decrease, app and content prices may fall
  • Enhanced Convenience: Third-party payment integration allows users to choose familiar payment methods

For Developers

  • Reduced Commissions: Possibility to accept payments at lower commission rates than Google Play's billing system
  • Improved Profitability: Decreased commission burden allows for greater revenue retention
  • Direct Customer Relationships: Direct website payments enable better customer data management

Security Concerns to Consider

The opening of third-party app stores raises legitimate security concerns. Apps that were previously subject to Google Play's strict review process may now be installed from stores with different standards, potentially increasing risks of malware and fraudulent applications.

Users will need to exercise greater caution in selecting trustworthy app stores and payment services, requiring heightened security awareness compared to the past.

Looking Ahead

The concrete impacts of the Smartphone Competition Law are expected to become clear over the next several months to a year. Key areas of focus include:

  • Google's commission rates for external redirects
  • Adoption rates of third-party payment services
  • Occurrence of security incidents
  • Fluctuations in app and content pricing

Internationally, similar regulations have been implemented, including South Korea's "Anti-Google Law" and the EU's Digital Markets Act (DMA). Japan's Smartphone Competition Law is part of this global trend, and further regulatory enhancements or adjustments may occur in the future.

Conclusion

The enforcement of the Smartphone Competition Law marks a major turning point for Japan's smartphone market. While users gain more choices and developers access expanded revenue opportunities, addressing security risks becomes increasingly important.

Whether this legislation truly creates a fair competitive environment and delivers benefits to both users and developers remains to be seen. Close monitoring of future developments will be essential to assess its long-term impact on the mobile ecosystem.

Reactions in Japan

Finally, the monopoly of Google and Apple is breaking down with the new smartphone law. As a developer, I'd be happy if commissions decrease, but it really depends on the specific rates. Half hopeful, half anxious.
