"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 5 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 5 Universities (Joining and Welding Research Institute, Osaka University, Institute for Materials Research, Tohoku University, Materials and Structures Laboratory, Institute of Integrated Research, Institute of SCIENCE TOKYO, Institute of Materials and Systems for Sustainability, Nagoya University, Laboratory for Biomaterials and Bioengineering, Institute of Integrated Research, Institute of SCIENCE TOKYO, 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 (DEJ²MA Project)" has been carried out through the inter-institute cooperative research activities by the 6 research institutes from 5 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.

Materials and joining technology make progress day by day, and natures of the joints that are created from them cannot be understood without close investigation of structures of the joint interfaces and the material structures. In order to achieve these purposes, Joint Interface Microstructure Analysis Room carries out observation of microstructure of joint interfaces and materials by transmission electron microscope (TEM) equipped with analysis functions, and supplies technologies for preparation of TEM specimen of dissimilar joint or composite materials etc. with focused ion-beam (FIB) and ion milling apparatuses.

Joint Interface Microstructure Analysis Room provides following services.
(1) Analyses of interfacial microstructures requested by staffs and joint researchers of the institute.
(2) Guidance and support for analysis and evaluation of results from TEM observation.
(3) Education of principles of TEM to students and joint researchers, and training of operations of TEM and associated apparatuses.
(4) Allover operations and maintenances of TEM and associated systems.

And the room maintains and improves techniques for TEM observation of joint structures through independent study about metallographic study of dissimilar precise joining, etc. using TEM.

Global D&I (Diversity & Inclusion) Promotion Office will promote the development of an environment that maximizes the strengths of JWRI and all members by truly embracing diversity and respecting the individuality of each person, regardless of gender, nationality, age, cultural background, etc., in order to achieve the SDGs, which aim to realize a society where "no one is left behind. In response to the trend toward internationalization in academic research, JWRI will develop international joint industry-academia research based on the international network we have established to date. JWRI aims to develop competent human resources to face global challenges, to strive to stimulate innovation in joining science as the world-leading research in the field of welding and joining, and to realize the institute where diverse human resources can play an active role.

New Normal Manufacturing Consortium Office deals with not only basic researches for generating advanced materials but also developments & educations of their applied technologies in order to establish Material Innovation Strategy. As for the creation of advanced materials, new high-functional (environmentally) adaptive materials is developed by using the advanced processing technologies. In addition, in order to achieve "Carbon Neural 2050", optimum structural design is studied through the appropriate selection of multi-materials and joining technologies with the aid of Artifi cial Intelligence computational science.
