The Japan Fair Trade Commission (JFTC) announced on Monday that it has designated Apple Inc., its Japanese subsidiary iTunes K.K., and Google LLC under the new smartphone software competition promotion law.

The law targets dominant IT companies in the smartphone app market, regulating areas like smartphone operating systems, app stores, web browsing software, and search engines.

The primary aim of the law is to prevent these giants from blocking market entry for other companies or giving preferential treatment to their own services. The law will take full effect in December, with the designated companies required to correct any problematic practices.

Apple will be required to allow other companies into the App Store business instead of monopolising it, fostering price competition. Google will be prohibited from displaying its services in search results instead of favouring them.

In response, both companies expressed concerns, with Apple questioning the impact on user experience and Google vowing to engage in discussions to ensure fairness.
