Key Takeaways
1. Japan’s digital market competition body has mandated Apple and Google to create an open ecosystem under the Smartphone Act.
2. Apple must remove restrictions on browser engines for iOS by December 2025, allowing browsers like Firefox and Chrome to use their own engines.
3. Apple’s current policy requires the use of its WebKit engine for iOS, which it defends by citing security and performance concerns.
4. New regulations prohibit unreasonable technical barriers and financial burdens on alternative browser engines and require the removal of outright bans.
5. The Mobile Software Competition Act (MSCA) will require Apple to provide choice screens for browsers post-activation, starting in December 2025.
Japan’s digital market competition body has released its final findings on the assessment of browsers and web applications. The broad legislation under the country’s Smartphone Act compels companies like Apple and Google to create an open ecosystem. This could spell trouble for Apple’s longstanding limitations regarding browser engines on iOS.
Deadline for Apple
As noted by Open Web Advocacy, a nonprofit group that provided input on the report, Apple has until December 2025 to lift all restrictions on browser engines for iOS. This change would allow browsers such as Firefox, Chrome, and Opera to operate using their own engines.
Apple’s Policy on Browser Engines
Currently, Apple’s browser engine policy requires the use of its own WebKit engine for iOS, which powers Safari. Apple has historically justified this restriction with claims about security and privacy concerns. They argue that WebKit is specifically optimized for iOS, offering a secure user experience, while alternative engines could lead to fragmentation and a poorer performance.
Interestingly, the lack of browser competition on iOS means that Safari, Apple’s own browser, brings in considerable revenue for the company. Advocates for an open web have criticized Apple’s de facto ban, stating that these policies limit user choices and stifle the growth of secure alternatives. The European Union’s Digital Markets Act (DMA) forced Apple to lift some of these restrictions.
Japan’s Smartphone Act Regulations
The new rules clarify that vendors cannot create unreasonable technical barriers for alternative browser engines while allowing them to adopt these engines. Additionally, it prohibits placing financial burdens on app providers. Vendors are also required to remove any outright bans that could restrict competition within their platforms.
The Mobile Software Competition Act (MSCA) obligates vendors to provide choice screens for browsers and other software. Apple will need to show these screens “promptly after first activation.” Set to take effect in December 2025, the MSCA will press Apple to open its ecosystem to third-party browser engines.
