Japan Investigates Microsoft Azure Antitrust Violations

The Japan Fair Trade Commission (JFTC) has opened an investigation into Microsoft Corporation, Microsoft Japan Co., Ltd., and Microsoft Ireland Operations Limited for suspected violations of the Antimonopoly Act related to Microsoft Azure cloud services. The investigation focuses on allegations that Microsoft restricts enterprises from using its software in combination with competing cloud services, either by prohibiting combined use or by modifying trade terms to increase user costs when used with competitors. The JFTC is seeking information and comments from third parties by April 3, 2026.
