Driving transformation and earning trust.
Empowering global innovation through advanced X-ray technology

This year marks the 75th anniversary of Rigaku. Less than 1% of companies survive beyond decades. Rigaku has continued to grow and prosper over such a long period of time, which is the clear evidence of the efforts and dedications made by our predecessors, and great support and trust from our customers all oiver the world. We would like to express our sincere gratitude for all of them.

Guided by our corporate mission—To contribute to the enhancement of humanity through scientific and technological development—Rigaku has continuously pursued innovation and excellence in X-ray analytical and measurement technologies . As a result, we have established a unique global position in the industry, providing unparalleled quality and value from comprehensive solutions with the X-ray technology supporting both research and industrial applications.

The pace of change continues to accelerate in today’s world. To further strengthen our unique market position and kkep growing, we must never stand still. Instead, we should keep updating ourselves. We are committed to staying ahead of the market, driving the next wave of innovations with a strong spirit of self-start and a relentless drive for transformation.

We do not see this 75th anniversary as merely an opportunity to reflect on the past. Rather, we view it as an important milestone to define the future of Rigaku—shaped by “Lab to Fab,” “Global One Rigaku,” and the “Rigaku Competencies.” The Rigaku's future will be built and shaped not only by ourselves, but together with all those who have supported us including our custoemrs and partners along the way.

We look forward to your continued support as Rigaku embarks on its next stage of growth.
