About Us

Working toward a world without breast cancer.
Japan Breast Cancer Research Group (JBCRG) is a non-profit research organization conducting and coordinating clinical studies with the aim of improving breast cancer treatment.

JBCRG was established by a group of physicians committed to clinical research with the aim of improving treatment and outcomes for patients with breast cancer. It has grown into a national network of breast cancer specialists conducting clinical trials voluntarily in addition to their clinical duties.

We are supported in our activities by nurses, pharmacists, clinical laboratory technicians, clinical research coordinators, and many other professionals. We work together to maintain patient safety and the high quality of our clinical studies.
