Japan: United Kingdom Competition and Markets Authority and Japan Fair Trade Commission signed Memorandum of Cooperation on application of competition laws

On 30 September 2025, the Competition and Markets Authority (CMA) of the United Kingdom and the Japan Fair Trade Commission (JFTC) signed a Memorandum of Cooperation (MoC) to promote cooperation, coordination, and communication of information in competition law enforcement. The MoC covers notifications of matters affecting the other’s important interests (including mergers), options to coordinate timings and remedies, requests for information (with written particulars), permitted use of shared information, confidentiality safeguards, treatment of personal data, and explicit exclusions for immunity/leniency materials absent the provider’s written consent. It recognises each authority’s legal limits and resource constraints, allows involvement of UK concurrent regulators under specified safeguards, and provides for dialogue on legal or practice changes.
