Our vision is a world without breast cancer.
Working Toward a Cure for All Cases of Breast Cancer

For the benefit of all patients and their families whose lives have been or will be affected by breast cancer, the JBCRG is working to improve breast cancer treatment and outcomes. Our ultimate aim is a world in which all cases of breast cancer are curable and no more lives are lost to this disease.

Our Principles

  • We conduct research in a way that ensures the scientific validity of our findings.
  • The human rights of patients with breast cancer are our top priority. Our research is conducted in accordance with national and international ethical standards.
  • We are committed to transparency regarding the funding of our research.


Norikazu Masuda

The Japan Breast Cancer Research Group (JBCRG) has contributed to the progress of health care for breast cancer patients nationally and internationally through its clinical researches that have lauded remarkable achievements, including a response-guided treatment strategy for primary breast cancer using neoadjuvant therapy, new therapeutic strategies for advanced/recurrent breast cancer, and real-world evidence capturing the unmet needs of breast cancer patients. Moreover, as a member of the Breast International Group (BIG), the world’s largest international network of academic research groups for breast cancer, JBCRG has been active in collaborative research projects, cooperating with a number of international study groups, which aim to bring innovations to breast cancer care at a global perspective.

Based on our abundant experience in clinical and translational researches, we will further promote researches on new technologies and therapeutic approaches, which will give us valuable scientific insights to make breakthroughs in clinical outcomes.

Our mission is to develop the best treatment for every person suffering from breast cancer. Carrying on the footsteps of the great former Representative Directors, Dr. Masakazu Toi and Dr. Shinji Ohno, I feel the magnitude of the responsibility to meet the expectations toward JBCRG as it enters into its full maturity. I will dedicate myself to this role and exert my knowledge and experience to the fullest extent. I sincerely ask those who are concerned in our fight against breast cancer for your continuous support and cooperation in pursuing our challenges.
