So far, many important researches were carried out as cooperative researches. The committee of cooperative researcher plays an important role for their promotion. The Japan Radiation Research Society contributed to establishment of Radiation Biology Center and has been supporting the management of this Center and the promotion of cooperative research. However, the focus of radiation biology research is recently changing in Japan and around the world. Therefore, we will present the current result of cooperative researches and discuss the role to promote the future research of radiation biology.
