Strategy Office for Promotion of Inter-Institute Collaborations” has been established in JWRI as the headquarter to carry out the Project “Development of Inter-Institute Collaborations of 6 Research Institutes from 6 Universities for Strengthening Material Innovation Force”, which has been supported by the Ministry of Education, Culture, Sports, Science and Technology since 2022. Through promotion of the inter-institute collaborations of the 6 research institutes from the 6 Universities (Joining and Welding Research Institute, Osaka University, Institute for Materials Research, Tohoku University, Laboratory for Materials and Structures, Tokyo Institute of Technology, Institute of Materials and Systems for Sustainability, Nagoya University, Institute of Biomaterials and Bioengineering, Tokyo Medical and Dental University, Research Organization for Nano & Life Innovation, Waseda University), the project has been carried out for acceleration of the problem-solving and the creation of innovations, which are based on social demands, and thus for strengthening material innovation force. The related research project “Design & Engineering by Joint Inverse Innovation for Materials Architecture (DEJI2MA Project)” has been carried out through the inter-institute cooperative research activities by the 6 research institutes from 6 Universities for acceleration of the problem-solving and the creation of innovations in the interdisciplinary research fields; Environmental and Energy Materials, Biomedical and Healthcare Materials, Information and Communication materials.
