Who's Who Legal Competition: Lawyers

Kentaro Hirayama’s practice focuses on competition and antitrust law and government regulations. He has counselled European, American, Asian and Japanese clients in a number of cartels, unfair trade practice and abuse of standard essential patents, as well as merger filings including high-profile Phase II cases.

His skill and experience in competition and antitrust law is widely recognised, and in 2016 he was the only Japanese attorney named in Global Competition Review’s “40 Under 40” list of the world’s leading antitrust lawyers under the age of 40.

Mr Hirayama worked for the Japan Fair Trade Commission from July 2007 to June 2010, during which time he was a case manager in the Marine Hose case, among other high-profile international cartel cases, and also led an abuse of dominance case. In the course of these worldwide parallel investigations, he collaborated with foreign competition authorities in engagements such as information exchanges and coordination of simultaneous dawn raids, among others.

Since returning to private practice in 2011, he has been active as a non-governmental adviser (NGA) for the International Competition Network (ICN), a forum for approximately 100 national competition agencies worldwide. In addition, he also serves as an associate professor at the Tokyo University of Science and a lecturer at Tsukuba University School of Law, where he lectures on competition law.

WWL says: Kentaro Hirayama has a "great reputation" as "one of the most knowledgeable competition practitioners in Japan".
