About us

Advancing Healthcare
Through Preclinical Research

NISSEI BILIS Co., Ltd. is a preclinical CRO located in Koka City, Shiga, Japan.
Since our establishment in 1973, we have conducted studies on a wide variety of modalities, including pharmaceuticals, medical devices, and regenerative medicine products. In particular, we specialize in pharmacological studies and have established numerous drug-induced and surgically induced disease models.
Although we are a compact CRO with approximately 60 employees, we offer a high level of technical expertise. We provide attentive, flexible services that larger CROs may not be able to offer.
