Anderson Mori & Tomotsune

Professional notice


Things remain rosy at Anderson Mori & Tomotsune, the firm regularly labelled the best antitrust team in Japan. Its four Who’s Who Legal: Competition nominees are all renowned practitioners across the antitrust bar: Hideto Ishida, Shigeyoshi Ezaki, Yusuke Nakano and Vassili Moussis. Moussis adds a much-vaunted dimension to Anderson Mori & Tomotsune’s practice as he is a specialist in EU competition law with a year’s training at DG Comp.

The firm is firing on all cylinders, Ezaki says, with much of its work remaining confidential. A taste of Anderson Mori’s deal work includes being counsel to Publicis in its now-defunct mega merger with Omnicom, and advising Thermo Fisher in its tie-up with Life Technologies on which Ishida and partner Etsuko Hara advised. The firm also acted on the sale of Heinz to Berkshire Hathaway and 3G Capital.

Cartel work is keeping Anderson Mori particularly busy, with the firm involved in almost all of the most significant matters being investigated by the Japan Fair Trade Commission (JFTC). The firm is representing a major Japanese company in the freight forwarding cartel probe, and another big domestic business in the power cable manufacturers’ investigation.

Anderson Mori & Tomotsune (AM&T) has a leading international antitrust and competition practice in Japan.  Our team consists of a number of highly specialized attorneys who have a wide-ranging experience representing clients before all the major antitrust authorities, including the JFTC, the US DOJ and FTC, the European Commission, China’s MOFCOM and NDRC, as well as many other authorities active in antitrust enforcement and merger control investigations.

AM&T has advised on many of the highest-profile, complex international cartel investigations and merger control transactions over the past decades. We regularly work in close cooperation with top competition firms and practitioners from around the world and are frequently called upon to help formulate and implement global antitrust strategies but also to ensure speedy merger control clearances. Towards that end, our Japanese attorneys work closely together with our native English speaking lawyers to provide advice and assistance at a level that matches the quality our clients are accustomed to receiving in their home jurisdictions.
