TOMOEGAWA group was founded in 1914 to meet the needs of first domestic production of telecommunication paper and electrical insulating paper. Now, we are expanding our business into the field of high-functional materials, which is the cutting edge of the times, and on the leading edge of the field of next-generation industry. We are achieving success by refining our technologies of paper making, coating, powder, and adhesion based on specialty paper products that make use of our electrical properties evaluation technology.

In recent years, with the spread of IoT, 5G, AI, car electronics, etc., the control of high voltage, high current, and high frequency is required for many electronic components.  In order to meet these needs, we are expanding our “iCas” brand product line, which controls heat, electricity and electromagnetic waves, to provide a variety of solutions for heat and noise.
