Firm overview:

Anderson Mori & Tomotsune is a full-service law firm formed by the winning combination of three leading law firms in Japan: Anderson Mori, one of the largest international firms in Japan which was best known for serving overseas companies doing business in Japan since the early 1950s; Tomotsune & Kimura, particularly well-known for its expertise in international finance transactions; and Bingham Sakai Mimura Aizawa, a premier international insolvency/restructuring and crisis-management firm.

Our combined firm provides an extraordinarily powerful value proposition. Housing all of these synergistic practices under one roof, and further increasing our resource scale, we have the capability to: (1) serve a multinational client base, (2) on in-bound, out-bound and domestic projects, (3) by providing expert, timely and cost-efficient advice, (4) across a full range of legal issues, and (5) in the largest, most complex, cross-sector transactions.

We are proud of our long tradition of serving international business and legal communities and our reputation as one of the largest full-service law firms in Japan. Our combined expertise enables us to deliver comprehensive advice on virtually all legal issues that may arise from a corporate transaction, including those related to M&A, finance, capital markets and restructuring/insolvency, and litigation/arbitration. The majority of our lawyers are bi-lingual and experienced with communicating, drafting and negotiating across borders and around the globe. We welcome the opportunity to work closely with clients and channel our resources towards our goal of achieving more together.

We are headquartered in Tokyo with branch offices in Osaka and Nagoya. Outside Japan, we have offices in Beijing, Shanghai, Singapore, Hanoi, Ho Chi Minh City, Bangkok and London. We also have associated firms in Hong Kong and Jakarta.
