On behalf of the Organizing Committee, we would like to invite you to the International Conference on Hydrogen Medicine & Biology, Tokyo 2025. Hydrogen health medical biology has made remarkable progress over the past 18 years. Starting from basic research, the challenge is now to put it into practical use in society. It is expected not only to improve and treat serious diseases, but also to improve the quality of life of healthy people and contribute to the agriculture and fisheries industries. The diverse effects and efficacy of molecular hydrogen, as well as its characteristic of having almost no side effects are expected to go far beyond conventional wisdom and contribute to the welfare of mankind.
This conference will be held from November 7th to November 9th, 2025 at the Hideoki Ogawa Auditorium, Juntendo University, Tokyo, as a joint conference of the 5th annual conference of International Society for Hydrogen Medical Biology (ISHMB) with the 14th annual conference of Japanese BioMedical Society for Molecular Hydrogen Society for Molecular Hydrogen (JBMSH2), which is responsible for organizing this entire conference.
The main purpose of this conference is to promote the formation of a global academic hydrogen community. At the same time, we hope to contribute to the development of the hydrogen health industry by serving as a bridge between different fields and between industry and academia. Many challenges remain before practical application can be realized. Furthermore, this conference will be an opportunity to promote the development of hydrogen medicine to media around the world.
We look forward to welcoming researchers, clinical experts, business people, media personnel, and everyone interested in this field to this international conference.
Sincerely yours

Theme
Science creates Practice. Practice shines Science.
The symbol is a bridge with two "H's" side by side, which symbolizes the bridging between various fields and between academic and industrial societies.
The predecessor of the Biomedical Society for Molecular Hydrogen (JBMSH2) was founded in 2011. Since then, the number of scientific papers on molecular hydrogen in the field of life sciences has increased year by year. It is clear that a great many researchers around the world are attracted to the potential of molecular hydrogen and are conducting a wide variety of research on it.
Research includes research on the treatment of diseases such as cerebral infarction, neurodegenerative diseases, and metabolic syndrome, as well as research on the maintenance, recovery, and improvement of health, such as anti-aging and anti-fatigue.
In addition, the number of research reports in the agricultural field, such as the promotion of crop growth, is also increasing year by year. There are a variety of methods for administering molecular hydrogen in these studies, including not only inhalation of hydrogen gas, but also hydrogen water containing high concentrations of molecular hydrogen, hydrogen-containing infusions, and more.
Numerous animal models and human clinical studies have demonstrated that molecular hydrogen has the diverse effects including anti-oxidative, anti-inflammatory, anti-cell death, anti-allergy effects, stimulation of energy metabolism and immuno-system. Research into the mechanism by which this effect is exerted at the molecular level is also progressing. Research into molecular hydrogen medicine is interdisciplinary, and it is essential to have exchanges with researchers from fields other than life sciences, such as physics, chemistry, and even engineering. Our society will continue to move forward steadily in order to contribute to the happiness and welfare of humanity.
The International Society for Hydrogen Medicine and Biology (ISHMB) was founded in 2018. The establishment of the International Society for Hydrogen Medicine and Biology (ISHMB) was proposed by experts in the field of hydrogen biomedicine, mainly from China, Japan, Korea, Europe, and the United States, and ISHMB was launched as a federation of academic societies from each country. Therefore, we will hold the ISHMB conference as a joint conference with academic conferences in each country. It is an academic, non-political, non-profit organization. The purpose of this society is to strengthen academic exchanges and cooperation in the field of international hydrogen biomedical research, guide and supervise the hydrogen industry, and promote the healthy development of hydrogen biomedical and bioindustry.
