Innovative R&D activities and superior production processes meet clients' various needs


TOMOEGAWA is a development type company which develops and possesses many first-in-the-world and first-in-Japan products and technologies. Since its founding, its strength has been as "Chemists who also understand electricity", and it has expanded mainly to electronics business, unparalleled as a paper manufacturer.

Since inventing electrical insulating paper and telecommunications paper, it has cultivated both "Paper making" and "Coating" processes based on "Electrical properties evaluation technology" for over 100 years. Continuing to advances our development ability, technical ability and "Manufacturing", we also provide services in the research and development process and production process rather than being limited to simply providing products.

Always responding to the diverse needs of the times, we work diligently to improve customer satisfaction levels as a pioneer that continues to create new value.


Because it protects electrical equipment functions from heat, noise, etc., to maximally "utilize" them, we provide a variety of solutions via the "iCas" brand.

In order to realize a better future, we introduce a new product made of highly functional materials that meet the needs of the times, realizing the technological strength of our company's "paper making, coating, powder, and pressure-sensitive adhesives.".
Including our "lead frame fixing tape", which has established a top share in the world, we introduce electronic parts materials to support the electronics industry.
We introduce touch panels utilizing proprietary glue/adhesive technology and coating technology, and optical film products for displays such as LCD and PDP.
As a world leading manufacturer specializing in toner, we possess abundant knowledge regarding micro-particles and introduce micro-particle products (toner, etc.) to develop and expand business globally.

Utilizing TOMOEGAWA's proprietary multi-layer coating technology and special paper making technology, we skillfully use paper and a variety of materials to propose sheets that will manifest the features our customers need.
Since succeeding in making the manufacture of our electrical insulating paper and telecommunications paper domestic, we have composited paper with other materials and applied peripheral technology to present many innovative products.

Products for Optical Communication

based on our company's coating technology and adhesive technology, we propose "optical fiber wiring and connection solutions" which contribute to the field of optical telecommunications.
