About

Provided by Anderson Mori & Tomotsune

Competition laws evolve constantly, and agency enforcement practices often diverge from black-letter statutes, ordinances and guidelines. Companies therefore need experts with deep knowledge and hands-on experience from recent enforcement matters—advisors who can explain current trends at the Japan Fair Trade Commission (JFTC) and international competition enforcement agencies. AMT has an extensive track record under the Japanese Antimonopoly Act ("Antimonopoly Act") and in international competition law, including matters involving foreign regulators. Our competition team includes attorneys with work experience at the JFTC and the European Commission, as well as with deep knowledge of enforcement practices at the U.S. DOJ and the FTC, enabling first-class advice across the full spectrum of competition and antitrust law.
