Since TMI was founded in 1990, the firm has worked to create a law firm which is distinct from any other in Japan and to recast the image of both lawyers and patent/trademark attorneys. During the past 26 years, the firm has experienced rapid organic growth, both numerically and geographically, while maintaining its progressive culture. Starting in 1990 with 43 personnel, including 10 lawyers and two patent attorneys, TMI now has 389 lawyers and 68 patent/trademark attorneys among a total of 768 personnel as of January 1, 2017, and it has become one of the five largest law firms in Japan. The firm has branch offices overseas, in Shanghai, Beijing, Yangon, Singapore, Ho Chi Minh City, Hanoi, Phnom Penh and Silicon Valley. TMI provides a wide range of global legal services through its Chinese service group, French practice group and India desk located in its Tokyo office and its joint venture relationships in Japan with Simmons & Simmons (UK), Morgan, Lewis & Bockius (US), Wakely Foreign Law Office (Canada) and Arqis Foreign Law Office (Germany).

TMI provides a comprehensive range of legal services regarding international corporate transactions and international investment and trade business transactions. The firm continuously seeks to expand its support for the global business development and needs of its clients – both Japanese and international innovative companies – with services ranging from the acquisition of patent rights to licensing, mergers and acquisitions, financing matters, down to dispute resolution.
