Hideto Ishida is a partner at Anderson Mori & Tomotsune, and counsels a variety of domestic and foreign multinational companies in Japanese competition and distribution regulatory matters, including those relating to mergers and acquisitions, joint ventures, distribution agreements, joint research and development agreements, and other cooperation agreements. He also represents many domestic and foreign companies in investigations before the Japan Fair Trade Commission involving price cartels, bid rigging and similar serious alleged violations. He served for seven years as the first attorney appointed as a special investigator with the Japanese Fair Trade Commission and thus has a keen sense of the actual and practical application of antitrust and distribution regulations to companies doing business in Japan.

He also writes many English or Japanese articles and was appointed as Professor and Lecturer at the Faculty of Law, Tokyo University (1995-1999), and the Faculty of Law, Hitotsubashi University (2003-present). He was a graduate from Tokyo University (LL.B., 1976), and Harvard Law School (LL.M., 1989).
