About our Tokyo, Japan: office

Founded in 1989, Momo-o, Matsuo & Namba (MMN) is based in Tokyo, Japan and offers a complete array of corporate and commercial legal services to its domestic and international clients. MMN prides itself on the ability to meet the complicated demands of its diverse clientele in an ever-changing world economy.

MMN has received long-standing recognition for its excellence in key practice areas such as complex litigation and arbitration, corporate and M&A, bankruptcy, antitrust, labor and employment, and intellectual property including brand protection.

While the firm and many of its partners are nationally and internationally recognized experts in their fields of practice, MMN has maintained a boutique-firm mindset when it comes to the individual attention each client deserves. Many attorneys in the firm have obtained advanced legal degrees abroad, are members of the New York Bar and have extended work experience at foreign law firms in the United States and Europe.

It is this depth of experience that enables MMN to provide comprehensive day-to-day advice and counseling to its clients on a wide range of domestic and cross-border matters and, in turn, maintain its client relationships over the long-term. Through these relationships, MMN can and will continue to grow organically as a mid-sized law firm practicing at the highest level in many areas of law.

MMN is the sole Japan member of INTERLAW. INTERLAW is a top-ranked international law firm network comprised of independent law firms working collaboratively on a “Best Client” basis. See
