  • Measuring people's health status in everyday life—the potential of sensing research to capture invisible information
  • Professor Yosuke Kurihara
  • With the advancement of an aging population and the increasing diversity of living environments, the importance of technologies for understanding the state of people, buildings, and the environment on a daily and continuous basis is growing. Professor Yosuke Kurihara, based on sensing engineering, is developing an integrated approach from measurement to analysis and utilization of biological information, and is applying it to a wide range of fields such as medicine, nursing care, and architecture. He is promoting research rooted in real society by identifying problems through dialogue with people on the ground and solving them with technology.

  • How are "learning teams" created? – Transformational leadership and communities of practice that overcome knowledge-sharing barriers.
  • Professor Mutsumi Matsuo
  • Professor Mutsumi Matsuo's research, which focuses on the relationship between transformational leadership and communities of practice, clarifies the mechanisms of knowledge sharing within teams. The study was published in a highly regarded academic journal in the field of knowledge management, recognizing that knowledge sharing is promoted not through direct leadership intervention, but through the creation of a collaborative learning environment, and demonstrating the potential to suppress "knowledge concealment" that can occur within teams.

  • We are challenging ourselves to create phenomena never before seen through the development of highly functional photochromic molecules.
  • Professor Jirou Abe
  • Molecules whose molecular structure and color reversibly change upon light irradiation are called "photochromic molecules." Since the 2000s, Professor Abe has developed numerous groundbreaking molecules in the field of designing and synthesizing these photochromic molecules, bringing about significant advancements in this research area.
    Its various research achievements have attracted international attention and received high praise, leading the world in the field.

  • Why do people feel attached to brands? — Unraveling the essence of "brand relationships"
  • Professor Susumu Kubota
  • Professor Nobuhiko Kubota, who specializes in theoretical marketing theory, published "Brand Relationships" (Yuhikaku) in 2024, which summarizes the research he has been working on for many years.
    This book, which covers everything from the fundamentals to the overall picture of brand relationships, has been highly praised from various quarters and has received awards from multiple academic societies.

  • We have established an evaluation method using the electroluminescent (EL) method that does not cause performance degradation of perovskite solar cells.
  • Assistant Professor Itaru Kifuku
  • Perovskite solar cells are expected to become widely adopted in the future because they possess features that compensate for the weaknesses of conventionally used silicon-based solar cells.
    Assistant Professor Itaru Raifuku established a method that allows the EL method, one of the evaluation techniques used for conventional silicon-based solar cells, to be applied to perovskite solar cells, attracting considerable attention at international conferences.

  • Using accounting and AI to spot "suspicious companies"—a study deciphering signs of fraud hidden in the "writing style" of documents.
  • Professor Kenichi Yazawa
  • Accounting fraud has a serious impact on the entire capital market, but if the early signs of fraud can be detected, the damage can be prevented. Therefore, in recent years, research into analyzing corporate disclosure documents to identify signs of fraud has attracted global attention.
    Professor Kenichi Yazawa, in collaboration with Azusa Audit Corporation, is developing an AI model that uses AI (machine learning and natural language processing) to detect early signs of accounting fraud by focusing on both the numbers (financial data) and text (text data) in the securities reports published by companies.

  • The development and social application of a nationwide small-area future population projection system received the "2024 Symphonica Statistical GIS Activity Encouragement Award".
  • Professor Takashi Inoue
  • Traditionally, highly reliable population projections have only been conducted at the municipal level. However, Professor Inoue has established a method for projecting future populations for smaller areas by adopting the concept of "population potential," which defines the sum of the influence that surrounding areas exert on a given region. He developed the "National Small-Area Future Population Projection System," and the realization of this applied method, which has led to social applications, has been highly praised.

  • A new book, "The Defeat of Emperor Showa: The Struggle Over Article 1 of the Japanese Constitution" (Chuko Sensho), has been published.
  • Professor Kyo Komiya
  • The Japanese Constitution, promulgated on November 3, 1946, and enforced on May 3, 1947, stipulates that the Emperor's position is that of a "symbol." Traditionally, this was thought to have been established by Emperor Showa's "sacred decision" to accept this position. However, Professor Komiya, after analyzing new documents, has come to the conclusion that there was no such "sacred decision," and in 2025, he compiled his findings into a book that was published.

  • We pursue nonlinear systems that cannot be represented in a single form, aiming to contribute to future automated systems.
  • Yuji Asai
  • "Nonlinear systems" are systems where input and output values are not simply proportional. Mr. Asai is mathematically approaching the path to further automation by controlling these systems, which are said to account for 99% of the world's systems, with greater precision than ever before. He received an award at an academic conference during his first year of doctoral studies, and even now, after completing his doctorate, he is diligently working to further deepen his research.

  • Professor Hironori Maskawa
  • We are now in an era where generative AI is used in various aspects of daily life. With an eye on building a new educational environment, Professor Masukawa is collaborating with the Japan Kanji Aptitude Testing Association on "Learning Environments and Assessment for Cultivating Language Ability in the AI Era," aiming to realize new ways of learning for students by utilizing insights from learning science and not being bound by traditional teaching methods.

  • Explaining the movement of objects and artists' brushstrokes through physical calculations
  • Professor Yonghao Yue
  • When watching movies, today's CG seems to depict various real-world objects as they are. However, it is still difficult to accurately reproduce the light (color) and movement of objects through calculations, and many parts of it are done by hand by artists. Professor Raku is conducting research to realize even more accurate CG through a mathematical approach.

  • Yokohama City Library introduces Japan's first AI-based book search system
  • Professor Toshihiko Nozue
  • The AI-based book search system, developed in collaboration with Fujitsu Japan Ltd. as part of the "Near-future libraries and new learning" project led by Professor Toshihiko Nozue, was introduced to the Yokohama City Library in January 2024 and the Okinawa Prefectural Library in March. This is the first AI-based search system for library books in Japan (according to the research project).
    The project aims to create a model that evolves libraries from mere "collections of books" into places that support the learning of each and every citizen. This system was developed as one of the concrete tools toward this new model. It is designed so that users can find literature that they have not encountered before, based on their interests and needs, without relying on keywords. This initiative shows the future of learning and the ideal form of libraries that support learning.
