Antitrust Law | Japan


Morrison & Foerster’s Japan Antitrust practice advises clients on a wide range of antitrust matters, including transactions and agency investigations. Our work includes cartel, monopolization, unfair trade practices and administrative fine (kachokin) cases as well as merger reviews. In addition, our antitrust lawyers in Tokyo provide counseling to clients on a wide variety of issues, such as pricing policies, intellectual property licensing, patent pools, distribution arrangements, trade associations, unfair trade and deceptive advertising issues, and antitrust compliance programs.

Our Japan antitrust practice has been recognized by the Global Competition Review, Chambers Asia Pacific, The Legal 500 Asia Pacific, PLC Global Counsel Handbooks, and Asialaw. In 2012, Global Competition Review recognized our Tokyo antitrust team as one of a few firms leading the Japanese antitrust law market.

The Japan antitrust practice is led by partner Kei Amemiya, one of the few private practitioners who has served as an investigator at the Japan Fair Trade Commission (“JFTC”), the competition authority in Japan. This experience, along with our knowledge of Japanese and international business cultures, enables us to provide top-quality strategic solutions for clients on Japanese competition law and regulatory issues. We work with clients in numerous industry sectors, including, automotive, chemical, technology, pharmaceutical, transportation, and consumer products.

Our capabilities expand beyond Japan-specific matters. We have a strong global platform to provide advice to clients on multi-jurisdictional issues. Our Tokyo antitrust attorneys work closely with our antitrust teams in Brussels and Washington, D.C. to provide coordinated global representation and advice. We have represented clients in obtaining multi-jurisdictional antitrust clearance for mergers and acquisitions, including the $2.5 billion sale of Elpida to Micron Technology, Hitachi's $4.8 billion sale of Hitachi GST to Western Digital, and Terumo's $2.6 billion acquisition of CardianBCT.
