Mochizuki Takashi

Mochizuki Takashi is an attorney at Toranomon Chuo Law Firm, a Tokyo practice based in the Toranomon district of Minato-ku. Admitted to practise in both Japan and the State of New York and also registered as a patent attorney, he concentrates on international litigation and arbitration alongside intellectual property work. His expertise in this field is recognised in his naming as Arbitration Law Expert of the Year in Japan at the Corporate INTL Global Awards 2026.

An internationally qualified Tokyo lawyer

Mochizuki Takashi brings an unusually international profile to his practice. He was admitted to the Tokyo Bar Association in 2009 and to the New York State Bar in 2017, and he registered as a patent attorney in 2024. He holds an LL.M. in international business and economic law from Georgetown University Law Center, and he gained in-house experience as counsel at an international manufacturing group, where he handled contract review and management, litigation, and compliance matters. Fluent in Japanese and English, he now provides global legal advice that draws on both his cross-border qualifications and his corporate background.

This combination of Japanese and United States admissions, a patent-attorney registration and an American legal education equips him particularly well for international arbitration and cross-border disputes. Arbitration is frequently the preferred method of resolving international commercial disputes because it offers a neutral forum, procedural flexibility and awards that can be enforced across borders. A lawyer who is qualified in more than one jurisdiction, comfortable working in English as well as Japanese, and experienced in how businesses actually operate is well placed to represent parties in exactly this kind of proceeding.

Focus on arbitration, dispute resolution and IP

Mochizuki Takashi's practice centres on international litigation and arbitration, with a particular capacity to handle cases involving parties, defendants or debtors located outside Japan. His work also encompasses intellectual property, including copyright matters, and extends to related areas such as dispute resolution generally, mergers and acquisitions, corporate governance, and trademark and patent disputes. This blend of contentious and corporate expertise reflects the reality that international disputes often arise out of commercial transactions and intellectual property rights, and that resolving them effectively requires an understanding of the underlying business and technical issues as well as of arbitration procedure.

For companies engaged in cross-border trade and investment, the ability to call on a single adviser who can manage an international arbitration while also understanding the corporate and intellectual property dimensions of the dispute is a considerable advantage. Mochizuki Takashi's profile allows him to offer that integrated perspective to clients on both sides of the Pacific.
