Momo-o, Matsuo & Namba


Founded in 1989, Momo-o, Matsuo & Namba (“MMN”) is based in Tokyo, Japan and offers a complete array of corporate legal services to its domestic and international clients.  

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

MMN’s robust antitrust team regularly defends clients against investigations by the Japan Fair Trade Commission and handles domestic and international antitrust litigation.  It has handled numerous international cartel cases working alone or in concert with European and U.S. counsel.  The firm also provides counsel on domestic and international antitrust issues related to commercial transactions.

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.   

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