About us


Atomic symbol: Atomic number: 6 Our unlimited vision for the future of carbon

Toyo Tanso is dedicated to unlocking the unlimited future potential held by carbon, and continues to pursue its goal of producing materials of ideal quality. In 1974 we became the first company in Japan to develop isotropic graphite, significantly expanding the possibilities of carbon use. Our products are now widely used in a variety of cutting edge technology fields, including the semi-conductor and aerospace industries. We base our values on our results and reliability as a pioneering manufacturer, and aim to be a global company that makes a valuable contribution to society.

Pioneer of the industry in developing isotropic graphite

Our business is graphite, a type of carbon produced at high temperatures of about 3,000℃. Graphite conducts electricity well because it has an even crystal structure. Graphite has been developed over the years to make it finer and more stable. We were the pioneers in our industry in developing a new material called "isotropic graphite" by cold Isostatic press, the result of many years of research and development. Isotropic graphite resolves many of the problems previously associated with carbon.

Pioneer of graphite products

Our isotropic graphite has the following features: excellent heat and electricity conduction, superb temperature and chemical durability, lightweight and easy to machine, and minimum friction and wear. These characteristics mean it is used in wide range of industries with the highest standards of reliability, most notably for atomic power, electric discharge machining and semi-conductors. Toyo Tanso is a pioneering company and a leader in the global industry. We have recently developed a diverse range of new products. These include functional composite materials, utilizing coating technology for the surfaces of graphite products. We continue on our mission of creating graphite with ever-greater functionality.

Expanding to a global business through flexible thinking and high ambition

We meet the carbon material needs of customers wherever they are in the world.We positively seek out business opportunities produced by international market trends.Our goal is to expand our global business through our production and sales bases, placed in strategic locations all over the world.







Multipolar Overseas Network

Toyo Tanso products have been highly evaluated in the USA and Europe from an early stage. We have further established local subsidiaries and dealers in all areas of the world to function as marketing and sales bases. Our system is based on a direct sales, which deepens our relationship of trust with customers. We have established three production bases around the world with Toyo Tanso USA,inc. in the US,GTD GRAPHIT TECHNOLOGIE in Germany, Europe. and Shanghai TOYO TANSO CO.,LTD. in China (Asia). Our business strategy is formulated around these key regions.

Increased importance of information sharing

We have created a unified production and sales system at our overseas bases to ensure customer needs are prioritized and fulfilled as quickly as possible. This has resulted in an ability to respond flexibly to the international market and to reduce production costs. Information accumulated from all over the world is gathered in order to ensure the continuous improvement of production. We keep in close contact with managers and engineers all over the world in order to share the latest information on market and user trends.
