Apple is making big changes to how iPhones work in Japan, all to comply with the country’s new Mobile Software Competition Act (MSCA), which kicks in from December 18, 2025.
The iOS 26.2 update brings support for third-party app stores, relaxed payment rules, and more freedom for users when choosing default apps. But don’t expect a total free-for-all—Apple is still keeping a close eye on privacy, security, and child safety.
Update
With iOS 26.2, Apple has rolled out one of the biggest overhauls to its App Store policies in Japan. Starting December 12, developers operating in Japan can now distribute their apps through third-party marketplaces, provided those platforms are approved by Apple and meet strict operational criteria. While it’s a step toward more competition, it’s far from the open model seen in the EU. Direct installs from websites are still not allowed in Japan—a move Apple says helps protect users from malicious apps.
This update affects only iOS users in Japan, meaning global users won’t see these changes unless similar laws are passed elsewhere.
App Stores
The major highlight here is the opening of iOS to third-party app stores. Apple will now allow these alternative marketplaces, but only after a review and approval process. They must follow Apple’s guidelines, and Apple will apply a process called “notarisation” to all apps—whether they’re from the App Store or elsewhere. This means apps will still go through automated checks and human reviews to prevent malware or system-breaking bugs.
That said, notarisation is less strict than App Store review. Apps distributed outside Apple’s store won’t be subject to content moderation—Apple won’t police what the app says or does, as long as it doesn’t violate core technical rules.
Payments
Japan’s MSCA Act is also changing how in-app payments work. Developers can now offer:
- Apple’s own In-App Purchase system
- Third-party payment options
- Redirects to external websites for digital goods
But there’s a catch. If a developer offers an alternative, they must still show Apple’s option side by side. Also, when users choose a third-party payment method, Apple will display a warning that refunds and customer service may not be handled by Apple anymore.
This move brings more flexibility for developers and could lead to lower prices or better promotions outside Apple’s payment setup.
Fees
To go with these new options, Apple has introduced an updated fee structure in Japan. It’s more complex but also more flexible depending on how apps are distributed and how payments are handled.
| Scenario | Fee/Commission |
|---|---|
| App Store Sales | 10% or 21% (based on eligibility) |
| Apple In-App Purchase (IAP) | +5% processing fee |
| Web-based purchases (linked in app) | 15% or 10% Store Services Fee |
| Third-party app stores | 5% Core Technology Commission |
According to Apple, most developers will pay the same or less than they did under the old system.
Safety
Opening up iOS comes with obvious risks, especially for younger users. Apple says it has built extra safeguards for kids and teens:
- Apps in the Kids category cannot link to outside websites for purchases
- Apps for users under 18 must include parental approval if using alternative payment methods
- Apps used by children under 13 can’t link to external payment sites at all
Apple is also keeping age ratings mandatory across all app distribution channels, whether from the App Store or third-party marketplaces.
Defaults
One of the most user-visible changes in iOS 26.2 is the freedom to choose your default apps during setup. Japanese iPhone users will now be able to:
- Choose a default browser and search engine
- Pick a preferred maps/navigation app
- Select a default app marketplace for future downloads
These settings can also be changed anytime via the Settings app. This marks a big shift from the usual Apple-first defaults like Safari and Google Search.
Developers
There’s more good news for developers in Japan. Apple is opening access to several iOS features, including:
- Non-WebKit engines for browsers (with strict privacy and security requirements)
- API access for voice assistant apps to launch via the iPhone’s side button
- A channel to request deeper access to iOS functions, though Apple warns it may reject requests that threaten privacy or security
Developers can look into these new tools and read the full guidelines on Apple’s official developer site.
With iOS 26.2, Apple is taking a major step toward complying with Japan’s new tech regulations while still holding on to its core principles around privacy and user safety. Although the changes are limited to Japan for now, they could set the tone for how Apple adapts to other markets with similar laws. The balance between openness and control is evolving, and Apple is trying to walk that line carefully.
