Japan's Fair Trade Commission has designated Google, Apple, and iTunes under a groundbreaking law aimed at preventing tech giants from monopolizing the smartphone market. The legislation, set for full enforcement in December, will regulate app stores, operating systems, browsers, and search engines. Violations will incur fines of 20% of Japanese sales, increasing to 30% for repeat offenses. The law applies to companies with monthly user bases exceeding 40 million and requires annual compliance reporting.
