PSI CRO Opens New Office in Osaka, Japan

PSI CRO, a Swiss-based global full-service contract research organization, has opened a second office in Japan located on Level 18 of the Hilton Plaza West Office Tower in Umeda, Kita-ku, Osaka.

PSI opened its first Japanese office in Tokyo in early 2025. By adding an Osaka location, PSI brings sponsors closer to experienced local teams and the local PSI team closer to the established site networks.

With a larger team operating from two strategic locations, PSI brings strong in-country knowledge and established relationships across Japan’s clinical research community, helping sponsors move faster with delivery that’s predictable, responsive, and grounded in local experience.

Sayaka Kaji, Japan Country Manager, said, “The new office in Osaka will ensure that sponsors in Japan can count on the same standard of excellence that defines PSI worldwide, with local experts who understand the region’s unique challenges and bring proven solutions to every project. I feel the spirit of 不撓不屈 (undaunted determination and indomitable will) in each team member as we strive towards our ambitious goals.”
