Background and Education

Hiro N. Aragaki, Esq., Ph.D, C.Arb is a Chartered Arbitrator and distinguished neutral with more than 20 years of experience, including almost a decade of full-time law practice at global law firms and service as a neutral since 2001. Recognized internationally for his experience in arbitration and mediation, he has trained judges and lawyers and is frequently called upon to consult on alternative dispute resolution (ADR) reform projects around the world. He brings energy, sharp analytic skills and a talent for thinking outside the box. He is particularly well known for shrewd case management.

As an arbitrator, Dr. Aragaki strives to design and manage the optimal procedure for a particular dispute. He believes in getting to a hearing on the merits as efficiently as possible and without over-lawyering, while remaining open to a variety of process enhancements aimed at achieving accurate results, such as tentative rulings and draft awards. He is familiar with civil and common law adjudicative approaches. 

As a mediator, Dr. Aragaki is known for investing extra work prior to the mediation to narrow the issues and ensure that parties and counsel come fully prepared. He sees his role as helping parties make the best-possible decision about settlement based on careful analysis and case evaluation, reality-testing about litigation risks and transaction costs, and creative problem-solving. He is accustomed to using a wide range of directive and facilitative interventions, as appropriate. For additional insight about his approach to mediation, please see the Counsel Comments tab for testimonials from attorneys with firsthand experiences working with Dr. Aragaki.
