About the Sasaki Institute

Corporate philosophy

“We contribute to the advancement of medicine and health care through research for patients, along with relevant research support.”

Basic policy

The Sasaki Foundation is the medical research organization consisting of Sasaki Institute, Kyoundo Hospital, and Shonan Medical Examination Center. The three organizations cooperate closely with each other. We are committed to promoting our people’s health. To this end we are conducting the research and development of prevention, diagnosis, and treatment of cancer, among other diseases, attempting to advance medicine and human resources, and striving to promote and disseminate better medical care. The Institute carries out basic research, delivering the solutions through the experimental findings while the Hospital and the Medical Examination Center perform clinical research by taking advantage of clinical information. In case experimental results are required for the clinical research, they are given the opportunity for experiments in the Institute.

Non-profit activities

Research on cancer and other diseases
Therapeutic research devoted to the maintenance and improvement of patients’ quality of life
Preventive medical research on cancer and other diseases
Programs to train clinical investigators

Our efforts

We strive to move research forward from a perspective different than others, enhancing our position in the scientific community. Among the four non-profit activities, we are engaged in ’research on cancer and other diseases’ and ‘programs to train clinical investigators.’ We are doing the cancer research to substantiate ‘living with cancer.’ Cancer is a genetic disease. Given that mutations in DNA inevitably occur in our lifetime, it is quite hard to avoid developing cancer. After treatment, the regrowth of remaining cancer cells, cancer stem cells, and metastasized cancer cells all cause a big challenge. The time to cancer recurrence varies from several months to decades. One critical direction is to devise the therapeutic intervention strategies to reconcile with dormant cancer cells for escaping death from cancer by delaying the onset of cancer regrowth as long as possible. As for the diseases other than cancer, diabetes is one of the significant disorders with many unsolved problems, which will also be addressed by the experimental research.

Research organization

The Sasaki Institute is dedicated to the basic medical research on diseases, mainly cancer, with three departments built on distinct research disciplines: genome, interactome, and proteome. Each department is comprised of a principle investigator as chief, two research scientists and one research assistant.

On the operation and management of public research expenditure

The Sasaki Foundation has implemented internal regulations “Regulations for the Handling of Public Research Expenditure” in accordance with the Guidelines for Management and Audit of Public Research Funds at Research Institutions stipulated by the Ministry of Education, Culture, Sports, Science and Technology effective as of February 15, 2007 (revised on February 18, 2014) and strived to properly use public research expenditure. In addition, we seek to prevent fraudulent behavior in research by enforcing internal regulations “Regulations for Responding to Misconduct in Research” in accordance with the Guidelines for Responding to Misconduct in Research by the Ministry on August 26, 2013. Conforming to these regulations, a hotline is placed in the Compliance Office of the Foundation Secretariat to receive reports of misconduct in public research expenditure use and research activities, from both internal and external sources.
