Litigation | Japan

Morrison & Foerster is the only global firm with a dedicated full-service litigation team in Japan.

We have over 25 full-time litigation attorneys in Tokyo, more than half of whom are fluent in Japanese. Our trial lawyers in Japan work seamlessly with our firm’s U.S. attorneys to provide creative and strategic approaches in commercial and intellectual property litigation in courts, administrative agencies, and arbitration venues. We are available locally, in real time, to interview witnesses and prepare them for deposition; gather and review key documents in Japanese; prepare trial strategy; and counsel clients in all aspects of litigation.

Our experience extends to numerous fields:

  • IP litigation in all major U.S. jurisdictions, including popular patent venues such as the Northern District of California, the Eastern District of Texas, and the Western District of Wisconsin, and before the International Trade Commission (ITC);

  • Adversarial patent license negotiations, worldwide;

  • Global antitrust investigations and litigation, and investigations commenced by the Japan FTC (we have one of the few JFTC-trained attorneys in private practice);

  • General commercial arbitration and litigation, from consumer class actions and product defect claims, to major construction and other commercial disputes;

  • Internal investigations in Japan and the region on alleged accounting misstatements, product quality, safety and labeling, construction defects, export control, whistleblower retaliation, and matters involving possible corrupt practices under the FCPA.

Morrison & Foerster's Litigation Department has been singled out for praise by the American Lawyer magazine, which noted that the Department had “the depth, breadth, and talent to win high stakes disputes.”

Morrison & Foerster's Tokyo office was awarded Litigation Law Firm of the Year and IP Law Firm of the Year by Asian Legal Business (ALB) Japan Law Awards 2013. Additionally, the Tokyo office was the exclusive winner in the Litigation category for Japan in the 2011 and 2010 International Law Office’s “Client Choice Award” for excellence in client services (based on a survey of 2,000 in-house counsel).
