It is our great honor to welcome all delegates to the 28th International Workshop on Rare Earth and Future Permanent Magnets and Their Applications (REPM 2025) in Tsukuba. Since the inaugural workshop held in Dayton, Ohio, in 1976, the REPM series has served as a premier international forum for permanent magnet research. This marks the fifth time Japan has hosted the event – following Hakone (1979), Kyoto (1989), Sendai (2000) and Nagasaki (2012) – and we believe that Tsukuba will be another success. Just as Osaka is now showcasing Japan’s scientific progress and vision of the future with Expo 2025, Tsukuba previously had the chance to do so with Expo 1985. Established as a Scientific City during those pioneering days, Tsukuba has grown to encompass over 30 research institutes and universities, including the National Institute for Materials Science (NIMS), among many others. We hope that REPM 2025, held at this major research hub, will spark fruitful discussions about rare earth and future permanent magnets as well as related research topics, including emerging trends such as high-throughput experiments and the use of AI, machine learning, and digital twins in materials science.

More than 220 abstracts have been submitted to REPM 2025 from 22 countries represented by 69 different cities. This highlights an interest and global efforts in permanent magnet research which are as high as ever. Once faced with the rare earth crisis in 2010, society keeps struggling with other challenges including supply chain risks, climate changes and geopolitical tension. As various nations begin to diversify the production of rare earth permanent magnets and accelerate the transition to green energy, the responsibility of scientific community is to conduct basic research and innovations on permanent magnets that can facilitate this process and ensure a sustainable future. We look forward to lively debates, new collaborations, and breakthroughs on permanent magnets and their applications.

We would like to thank the REPM Steering Committee, International Advisory Committee, National Organizing Committee, Program Committee, and Local Organizing Committee for their hard work and
assistance in organizing this workshop. We express our special gratitude to the organizations, companies, and individuals who sponsored the REPM 2025.
