Since its launch in 2008, our Antitrust and Competition Law Team has expanded in both quality and quantity in response to the deepening and diversifying needs of our clients as the risks in this area have increased.
In addition to its core of Japanese and foreign lawyers, our team also works with external individuals and teams, including former senior officials of the Japan Fair Trade Commission (see recent examples here), providing comprehensive antitrust and competition law services both domestically and internationally, as outlined below. We also handle emerging areas of practice, such as serving as a monitoring trustee in business combination review cases. Our expertise covers a wide range of industries, with a particular focus on sectors that are currently experiencing strong growth, such as manufacturing, life sciences, IT, energy and resources, and financial institutions.
The Antitrust and Competition Law Team handles not only matters involving Japan’s Antimonopoly Act, but also a broad range of international competition law matters. Our team has recently been joined by attorneys who are actively engaged in competition law matters under EU, Chinese, and South Korean law.
Furthermore, by leveraging carefully vetted international networks, together with the expertise of our attorneys, we have established a framework that enables efficient collaboration with competition law practitioners around the world. This allows us to handle multi-jurisdictional matters as well as matters involving specific foreign jurisdictions, particularly in relation to merger control filings, antitrust investigations (including cartels), and competition-related litigation.
By incorporating the insider perspective of former Japanese competition authority officials, we strive to provide practical solutions and achieve the best possible outcomes for our clients.
