Career

Hiro N. Aragaki, Esq., J.D., Ph.D, C.Arb, is a Chartered Arbitrator and mediator with more than two decades of experience serving as a neutral. Before joining JAMS, he practiced for nearly ten years at top global law firms, which gives him a deep appreciation of the pressures and strategies that shape high-stakes litigation. His energy, sharp analytic skills, and talent for thinking outside the box has consistently earned the trust of parties and counsel alike.

As an arbitrator, Dr. Aragaki prioritizes pragmatic case management and moving matters efficiently to a hearing on the merits without over-lawyering. He receives praise for his legal acumen and precise award writing, and his commitment to reaching accurate results under the law. He has been appointed as sole arbitrator, co-arbitrator, or tribunal chair in over 300 disputes, and is sensitive to the differences between civil and common law approaches to adjudication.

As a mediator, Dr. Aragaki is known for his thorough preparation and proactive engagement even before the mediation session begins. He works with counsel to balance careful case evaluation, candid reality-testing about risks and costs, deep listening to the needs of the litigants, and creative problem-solving. His cross-cultural perspective—shaped in part by his Japanese and Indian heritage and experience living in the U.K., Germany, and France—enables him to connect with diverse parties and deploy a wide range of directive and facilitative interventions.
