To protect the safety and health of workers, the National Institute of Occupational Safety and Health, Japan (JNIOSH) has long served as the nation's only comprehensive research institute in industrial safety and occupational health. For more than 80 years, since the establishment of its predecessor, the Research Institute of Industrial Safety, JNIOSH has advanced research and conducted investigations into occupational accidents, contributing to safer and healthier workplaces.

In fiscal year 2016, JNIOSH was integrated into the Japan Organization of Occupational Health and Safety (JOHAS). Since then, we have strengthened our role as a core institution supporting national policies and advancing research and practice in occupational safety and health. In fiscal year 2024, JNIOSH further expanded its responsibilities by assuming the functions of the Japan Bioassay Research Center, reinforcing our capacity to address the risks posed by chemical substances. Today, our institute is committed to three core missions: advancing fundamental and applied research on workers' safety and health; investigating the causes of occupational accidents; and conducting hazard evaluations of chemical substances to support effective risk assessment.

Despite steady progress in reducing fatalities, occupational accidents resulting in work absence remain a persistent challenge. Addressing this requires innovative and forward-looking approaches. We must respond to evolving risks associated with demographic change, globalization of the workforce, technological innovation-including artificial intelligence-and the impacts of climate change, such as heat-related illnesses.

In line with national strategies, including the 14th Occupational Accident Prevention Plan, JNIOSH is advancing research and practical measures across key sectors such as construction, manufacturing, and transportation. We are also strengthening efforts to address mental health, overwork, and emerging health risks from chemical substances and ionizing radiation. Ensuring that our research leads to tangible improvements in workplace safety and health is central to our mission.

Looking ahead, JNIOSH will continue to enhance its research capabilities and deepen collaboration with government, industry, and academia, both domestically and internationally. By promoting the effective application of our research outcomes, we aim to contribute to the prevention of occupational accidents and diseases and to the creation of safer, healthier, and more resilient workplaces.

All staff members of JNIOSH are fully committed to meeting the expectations of society. We sincerely appreciate your continued guidance and support.
