TOYO DENSEN will celebrate its 80th anniversary in 2025.
We are deeply grateful to our valued customers, business partners, and our dedicated employees whose efforts over the years have made this milestone achievable.
Founded in 1945, TOYO DENSEN was established with the core philosophy of “contributing to better living and the development of society not only in Japan, but around the world through components related to electrical appliances.”

During Japan’s period of rapid economic growth, the so-called “three sacred treasures” of home appliances—televisions, refrigerators, and washing machines—began to spread widely, creating demand for new construction materials.
Through countless discussions with customers and appliance manufacturers, we developed and released a wide range of original products, including insulated copper pipes for air conditioners and various installation components.
Turning one idea after another into tangible products was a continuous process of challenge and evolution. It was through this experience that the spirit of “TOYO-ism”—the belief in creating something new from nothing—was born.

Since our founding, the world—including Japan—has undergone dramatic changes. Yet, we have continued to adapt to the times and provide what society needs.
In recent years, awareness of environmental issues has been rising. At the same time, global warming has progressed to the point that air conditioners are now essential even in cold regions during summer.
Toyo Densen is focusing on developing products that contribute to global warming countermeasures, while responding to the growing demand for materials driven by these environmental changes and fulfilling its responsibility for the future.

I believe that the true value of a company lies in its ability to continue operating over time.
To achieve this, we must also confront the growing issue of labor shortages.

The adoption of AI and other technologies for labor-saving will become increasingly important. However, it is we humans who ultimately use and manage these technologies.
We will continue to foster employees who inherit the spirit of TOYO-ism and possess a pioneering mindset capable of venturing into global markets.
We will also further strengthen our product development capabilities to meet increasingly diverse needs and take on the challenge of manufacturing that goes beyond conventional ideas.
At TOYO DENSEN, we aim to be a company that continues to grow by staying close to the field, listening to voices, and turning them into reality.
As we step toward our 100th anniversary and beyond, we will continue striving to be a company that contributes to society for many years to come.
We sincerely appreciate your continued support and partnership.
