Mori Hamada & Matsumoto now has over 260 attorneys and a support staff of over 380, including legal assistants, translators and secretaries.  The firm's senior lawyers include a number of highly respected practitioners and leaders in the Japanese and international legal community, including the former presidents of the Daini-Tokyo Bar Association, the former president of the Japan Federation of Bar Associations, the past president of the Tokyo Bar Association, the former Secretary General of the Inter-Pacific Bar Association, a prominent professor of law at The University of Tokyo and a former Justice of the Supreme Court of Japan. 

Although organized as a traditional partnership with partners, associates and counsel, Mori Hamada & Matsumoto prides itself on its non-hierarchical structure.  All of its attorneys - from the most senior partner to the most junior associate - work closely together to provide clients with the level of service they require.

After a few years of practice, most of Mori Hamada & Matsumoto's Japanese-trained attorneys are sponsored by the firm to obtain graduate degrees from leading U.S. or U.K. law schools and then to work for one or two years at leading international firms in major international legal markets, including New York, London, Los Angeles, the Silicon Valley, Chicago, Hong Kong and Singapore.

The firm also has experienced lawyers with primary legal training in other jurisdictions, including the United States, the People's Republic of China, and the Philippines.
