Evolving Technological Development and Responsiveness to become a Growth Company that Contributes to Society

Sinfonia Technology has continuously advanced its core technologies—motor drive systems, power electronics, and system control—over many years. As a technology-oriented company that meets our customers’ needs through our strong technological development capabilities and responsiveness, we have provided a diverse range of technologies and products that contribute to the sustainable growth of society and industry.

Since our founding in 1917, Sinfonia Technology has evolved the rotating machinery technologies originally cultivated through marine electrical equipment, expanding it to automobiles, railways, aircraft, and space rockets.

Today, we are aggressively investing in semiconductor manufacturing equipment modules, which are indispensable for the production of semiconductors, and highly reliable electrical equipment for aircraft and space rockets, as growth drivers to expand our corporate scale.

In addition, by continuing to supply industry-leading and “Only One” products across a wide range of fields—including energy, factory automation, and public infrastructure—we aim to achieve sustainable enhancement of corporate value.

We also address social challenges such as global environmental changes and labor shortages by contributing to solutions through the provision of material handling equipment for energy resources, as well as automation and labor-saving equipment.

Many of our products are designed to operate with high precision under harsh conditions, such as vacuum environments, high altitudes, and cryogenic temperatures. This is made possible by the continuous evolution and refinement of our rotating machinery and power electronics technologies cultivated over many years—one of our core strengths.

By further advancing the technological expertise we have inherited for over a century, we will continue striving to contribute to the development of industry and achieve more sustainable corporate growth

Through our SR and IR activities, we would like to disclose to our shareholders and investors in a timely and easy-to-understand manner, including insights into our distinctive business model and technological foundations.

We sincerely ask for all of our stakeholders for your expectations and continued support for the sustainable growth of Sinfonia Technology Group.
