Greetings from the President

日本質量分析学会会長

It is my great honor to once again serve as President of the Mass Spectrometry Society of Japan (MSSJ). With a renewed sense of responsibility, I am committed to dedicating my efforts to the continued growth and advancement of our Society.
The MSSJ is a scholarly organization devoted to promoting both fundamental and applied research in mass spectrometry, and to advancing its technologies for the benefit of science and society. Our activities include the annual Conference on Mass Spectrometry, specialized divisions and workshops, and regional meetings held across Japan, which together provide a broad platform for scientific exchange and collaboration.
During my previous term as President (2021–2022), the Society faced unprecedented challenges due to the COVID-19 pandemic. To address them, we established a “Working Group on Society Reform” and formulated a set of proposals to guide the Society’s sustainable future. Building upon this foundation, subsequent leadership has placed strong emphasis on international collaboration.
In recent years, the MSSJ has strengthened ties with neighboring societies by signing Memoranda of Understanding (MoUs) with the Korean Society for Mass Spectrometry (KSMS), the Taiwan Society for Mass Spectrometry (TSMS), and the Chinese Mass Spectrometry Society (CMSS). These agreements have greatly enhanced opportunities for academic cooperation and personal exchange. The successful hosting of the 10th Asia–Oceania Mass Spectrometry Conference (AOMSC2025) in Ishigaki, Japan -bringing together over 660 participants, half from overseas, with more than 500 presentations - further demonstrated the vitality of our regional network.
Looking ahead, the MSSJ will continue to foster closer partnerships across the Asia–Oceania region, serving as a hub for collaboration, knowledge exchange, and innovation in mass spectrometry. Through these efforts, we aim to contribute to the global development of the field and to strengthen Japan’s role within the international scientific community.
