Japan’s Mobile Software Competition Act (MSCA) mandates that Apple must allow alternative browser engines on iOS, moving away from reliance on its WebKit engine. The law, set to be enforced by December 2025, aims to enhance competition and transparency by prohibiting Apple from imposing restrictive barriers on developers. This move follows similar pressures from the EU and UK but with more explicit guidelines, potentially leading to better performance and innovation in iOS browsers. Non-compliance could result in regulatory penalties, although the enforcement details are not fully disclosed.
