Apple opens iOS to third-party app stores in Japan – a monumental shift that’s got the developer community buzzing with possibilities. Announced on December 17, 2025, just ahead of the Mobile Software Competition Act (MSCA) taking effect on December 18, Apple has officially enabled alternative app marketplaces, third-party payment options, and more for Japanese iPhone users. As a tech enthusiast who’s long advocated for more open ecosystems (while appreciating Apple’s security focus), I’m genuinely excited about this move. It’s the first major non-EU region to get these features, building on the DMA changes but with tweaks that preserve more of Apple’s protective framework – like universal notarization for all apps and stronger child safety controls. For developers, this means new ways to reach users, lower fees in some cases, and fresh revenue streams, all while navigating a still-curated environment.
In this article, we’ll break down the changes, explore opportunities for devs, and speculate on the broader ripple effects. If you’re a developer eyeing Japan or just curious about iOS’s evolving openness, let’s unpack what Apple opens iOS to third-party app stores in Japan truly signifies – the dawn of a more competitive mobile landscape.
The Announcement: Apple Opens iOS to Third-Party App Stores in Japan
Apple’s December 17 update complies with Japan’s MSCA, a law aimed at curbing Big Tech dominance similar to Europe’s DMA but with key differences that Apple praises for balancing competition and safety. Starting with iOS 26.2, Japanese users can install approved alternative app marketplaces, sideload apps (through marketplaces, not direct web downloads), and use third-party payments.
Unlike the EU’s more fragmented approach, Apple retains notarization – a malware and basic security scan – for every app, regardless of source. This, Apple argues, maintains privacy and child protections that were weakened in Europe.
“These updates create new options for developers to distribute apps on alternative app marketplaces and to process app payments for digital goods and services outside of Apple In-App Purchase,” Apple stated, emphasizing continued platform-level safeguards.
The timing? Spot-on, beating the December 18 deadline and rolling out via iOS 26.2 (public release imminent as of December 18, 2025).

Key Changes: What Apple Opens iOS to Third-Party App Stores in Japan Entails
Apple opens iOS to third-party app stores in Japan with a structured framework:
Alternative App Marketplaces
- Developers can create and distribute via approved marketplaces (e.g., potential Epic Games Store, AltStore).
- No direct web sideloading – marketplaces must be vetted by Apple.
Payment Options
- In-App Purchase remains, but devs can link to external sites or use third-party processors.
- Fees: Core Technology Fee applies, but reduced for small devs; non-App Store distribution as low as 5%.
Browser and Assistant Flexibility
- Non-WebKit engines allowed with strict security.
- Side button can trigger third-party voice assistants.
Security and Privacy Safeguards
- Universal notarization for all apps.
- Platform-level parental controls intact (unlike EU fragmentation).
A comparison table vs. EU DMA:
This balanced approach has me intrigued – Apple opens iOS to third-party app stores in Japan without fully dismantling its ecosystem.
Opportunities for Developers When Apple Opens iOS to Third-Party App Stores in Japan
For devs, this is huge. Japan – a tech-savvy market with high iPhone penetration – offers:
- Lower Commissions: Bypass 30% cut for external payments.
- Direct User Relationships: Own marketplaces for better branding and data.
- Innovative Distribution: Game stores like Epic could thrive, bringing Fortnite back with custom payments.
- Niche Apps: Easier launch for region-specific tools without App Store hurdles.
Early movers? Epic Games plans a Japan store by late 2025, potentially reigniting their battle with Apple fees.
List of developer wins:
- Access to same APIs as App Store apps.
- Reduced fees for small businesses/video partners.
- Interoperability requests for hardware features.
Speculation: This could boost indie devs in gaming and productivity, with Japan as a testing ground for global expansion.

User Impact and Safety Considerations
Users gain choice: Install from trusted marketplaces, change defaults (browser/search/side button), and potentially cheaper apps.
Apple stresses safety: No web downloads reduce malware risks, and notarization scans everything. Child protections remain centralized – a win over EU’s fragmentation.
Curious point: Side button for third-party assistants – could we see Gemini or custom bots as defaults?
Global Ripple Effects and Predictions
Apple opens iOS to third-party app stores in Japan as the first non-EU rollout, signaling adaptability. Countries like South Korea, Australia, and India watch closely – this “Japan model” might become the template for balanced openness.
Prediction: By 2027, 50+ countries adopt similar rules, pressuring Apple toward unified global changes. For devs, Japan could be the gateway to Asia-Pacific growth.
Key Takeaways
- Alternative Marketplaces Live: Approved third-party stores now installable in Japan via iOS 26.2.
- Payment Flexibility: External processors or links, with fees as low as 5% off-App Store.
- Stronger Safeguards: Universal notarization and platform parental controls vs. EU.
- Developer Boost: Lower costs, direct distribution, same API access.
- No Web Sideloading: Safer than DMA, focused on vetted marketplaces.
Final Thoughts: My Excitement for What Apple Opens iOS to Third-Party App Stores in Japan Means
Honestly, Apple opens iOS to third-party app stores in Japan feels like a smart evolution – competition without chaos, choice with safeguards. As a fan of open ecosystems tempered by security, this MSCA approach wins over DMA’s fragmentation. For developers, it’s liberating; for users, empowering. My opinion: This accelerates innovation in apps we haven’t imagined, from localized gems to bold experiments.
Will it spread globally? I’m betting yes – the walled garden’s gates are creaking wider. What’s your take on this shift? Dev opportunity or security risk? Let’s discuss below.
