Japan


Our Tokyo-based attorneys deliver success to Japanese and international clients on the largest and most complex legal matters in the market.

With over 120 attorneys in Tokyo covering all major practice areas, including 50 Japanese bengoshi, MoFo has the largest and most diverse team of any international law firm in Japan. Nearly two thirds of our attorneys are fluent in both Japanese and English, and we work in real time with clients in Japan to provide the highest level of service.

We offer on-the-ground, market-leading capabilities in:

  • Mergers and acquisitions
  • Intellectual property and technology transactions
  • Real estate
  • Antitrust and competition
  • Litigation and arbitration
  • Global strategic alliances and joint ventures
  • Capital markets
  • Project finance and energy

Since opening our Tokyo office in 1987, MoFo has built its Japan practice into a fully integrated platform for cross-border and multijurisdictional legal advice. We have been lead counsel on some of the most significant Japan-related transactions in history, both inbound and outbound, and have become a go-to advisor for Japan’s leading technology and telecommunications companies, such as Fujitsu, Hitachi, Toshiba, and SoftBank.

In 2018 alone, we advised on one of the largest telecommunications deals in history (Sprint’s $59 billion merger with T-Mobile) and the largest Japanese inbound M&A deal since 2011 (advising Toshiba on the $18 billion sale of its semiconductor business – also the largest private equity and leveraged finance deal ever in Asia).

MoFo is also the first and only international firm in Japan with full-service, on-the-ground litigation capability, and the only international firm in Japan with a dedicated team specializing in licensing and other IP transactions, including the transfer, commercialization, and development of intellectual property.

We are consistently recognized by Chambers Asia-Pacific with more top-tier practice rankings and top-tier individuals than any other international firm in Japan. We are Band 1 ranked for Competition/Antitrust, Corporate/M&A, Intellectual Property, and Real Estate and have been recognized with more “Star Individual” attorney rankings than any other international firm in Japan.

MoFo was named “International Law Firm of the Year” in the Corporate Law category at the most recent Chambers Asia-Pacific Japan Awards, and we received the prestigious “Japan International Law Firm of the Year” award from Chambers for six consecutive years.
