Firm overview

Anderson Mori & Tomotsune is a full-service law firm formed by the merger and consolidation of the practices of three leading Japanese law firms: Anderson Mori, which established its reputation as one of the largest and most established international law firms in Japan since its inception in the early 1950s; Tomotsune & Kimura, particularly 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 exceptionally powerful value proposition. Housing all of these synergistic practices under one roof, and further increasing the scale of our resources, we are well-positioned to: (1) better serve a wide client base; (2) provide even more prompt and accurate advice across a broader spectrum of legal issues; and (3) handle the largest transactions in Japan, including those which are cross-sectoral and extremely complex.

Our combined expertise enables us to deliver advice on virtually all legal issues that may arise from a corporate transaction, including M&A, finance, capital markets, restructuring/insolvency, and litigation/arbitration. The majority of our lawyers are multi-lingual and experienced with communicating, drafting and negotiating across borders around the globe.

With a long tradition of serving the international business and legal communities, our superior expertise, coupled with our standing as one of the largest law firms in Japan, translates to not only high quality services but also time and cost efficiencies, which we share with our clients.

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, London and Brussels. We also have associated firms in Hong Kong and Jakarta.
