Japanese law firm Mori Hamada & Matsumoto (MHM) is set to plant its flag in the San Francisco Bay Area, marking its second major U.S. expansion in less than two years.

The office will be led by corporate partner Mikito Ishida, who will relocate from Tokyo and brings experience working with startups, venture capital, private equity and cross-border M&A. Ishida will be joined by MHM M&A partner Stephen Overton, who has been based in San Francisco since 2015.

Following the launch of its New York office in September 2023, “the decision to open an office on the West Coast reflects our dedication to broadening our presence in the region,” the firm said in a statement. 

Apart from being global hub for technology and advanced industries, the region is also witnessing a surge in life science, climate tech, and generative AI sectors. 

With offices now on both U.S. coasts, MHM said it was signalling its commitment to being a pivotal bridge between U.S. and Asian markets, particularly for technology and innovation-driven sectors.

“By situating ourselves in this dynamic and rapidly-evolving region, we are better positioned to support the growth and success of our clients through the provision of comprehensive, cross-border legal solutions, working hand-in-hand with law firms in the region,” the firm added. 

Japanese law firms have been pushing beyond its borders in recent times, following increasing interest from their domestic corporate clients in international markets, particularly in Europe. 

TMI Associates launched a Brussels office earlier this month, while Nagashima Ohno & Tsunematsu announced the opening of a London office in 2025. Nishimura & Asahi revealed plans to open in London and Brussels. Anderson Mori & Tomotsune also has offices in London and Brussels, while Atsumi & Sakai launched a Brussels branch this year.
