Subsequently, it was reorganized as the National Inter- University Research Institute in 1985 and then as the Inter-University Research Institute in 1989. Then, it became part of the Inter-University Research Institute Corporation, Research Organization of Information and Systems (ROIS) in 2004. On June 5, 2019, ISM celebrated its 75th anniversary. On behalf of ISM, I sincerely appreciate your understanding and long-standing support to the research and educational activities of ISM. Activities involving “big data,” “artificial intelligence,” “Internet of Things,” and “Industry 4.0” have become the source of the industrial competitiveness. Consequently, nowadays, not only researchers but the general public is increasingly interested in methods of effective data utilization in order to survive under a major social change called “Society 5.0,” and “Data Science,” which is the all-inclusive word to express various fields of mathematical sciences, including statistics, machine learning, and optimization, has also become well known. The Institute of Statistical Mathematics has three crucial objectives: “strengthening of the cooperative research function,” “expansion of the project of fostering and promoting statistical thinking,” and “globalization of the research field of statistical mathematics.” In fact, to realize these objectives, since 2010, we have been promoting our projects, such as the Network of Excellence (NOE) project, and implementing effective reorganizations. The NOE project aims to connect and cooperate with other organizations from industry, government, and academia. It could also contribute comprehensively and effectively to helping a lot of people who need our research outcome, and developments can be implemented through the project. We aim to make the systematic value creation design possible, which will be a guideline for “Society 5.0.” Furthermore, we set the School of Statistical Thinking to establish a base for developing professionals who would be leaders in the data-driven era in our v “project of fostering and promoting statistical thinking.” We have designed multiple programs for professional development and have realized many achievements. However, ISM as a research institute holding a large number of statistical mathematics researchers in Japan is also expected to become a core center to educate whole universities and industries in advanced data science. We plan to form a network of data science with higher educational institutes and to establish a management cycle of data science education through the outcome of our project of fostering and promoting statistical thinking. We shall continue to promote our research and educational activities with a strong orientation toward research grounded in reality, which has been handed down through generations of ISM researchers as a hands-on approach to research for 75 years.

The ever-increasing needs for statistical methods and ideas in various fields of science and technology led ISM to reorganize itself in 1985 as an in- ter-university research institute that puts a major emphasis on research col- laboration with all science disciplines. In April 2004, ISM began a new chapter as a member of the Research Organization of Information and Systems (ROIS), Inter-University Research Institute Corporation, which includes three other institutes: the National In- stitute of Polar Research (NIPR), National Institute of Informatics (NII), and National Institute of Genetics (NIG). In October 2009, ISM moved to Tachikawa and started its activities. It shares the new building with NIPR and the National Institute of Japanese Literature (NIJL). At present, ISM consists of three departments, four research centers, a school, a support center, a planning section, a council, and committees. The NIPR/ISM joint administration office was reorganized as the Tachikawa Ad- ministration Department of ROIS. All ISM activities are guided by the lead- ership of the director-general and three vice-director-generals. The Council of ISM implements any necessary recommendations. The Cooperative Re- search Committee organizes and facilitates collaborative research projects developed between staff at ISM and collaborators in other academic agencies. The Managing Committee of the School of Statistical Thinking, established in 2016, makes suggestions regarding projects of fostering statistical thinking. Three research departments, the Department of Statistical Modeling, the Department of Statistical Data Science, and the Department of Statistical Inference and Mathematics, form the active core of ISM with its 43 academic 1 staff and carry out research on either statistical theory or its application to other fields of science and industry. The Department of Statistical Modeling and its three groups study statistical modeling aspects in various fields. In the three groups of the Department of Statistical Data Science, efforts are concentrated on data collection and handling. The three groups of the De- partment of Statistical Inference and Mathematics are specifically concerned with the fundamental aspects of statistics. The four strategic research centers—Risk Analysis Research Center, Re- search Center for Statistical Machine Learning, Data Science Center for Creative Design and Manufacturing, and Research Center for Medical and Health Data Science—were established in 2005, 2012, 2017, and 2018, respec- tively, as main bodies for establishing the Network of Excellence (NOE) and performing project
