selection of raw materials,
improvement and development of products.


Graphite Drying, Crushing, Classifying

We have a factory for drying, crushing, and classifying of Graphite in Koriyama city, Fukushima.  We strive to produce high quality and low-cost products under strict quality control.

Raw Material Procurement

The main carbon we import is Natural Graphite.  Natural Graphite was previously mined in Japan, but is now depleted and relies on imports 100%.  We are selecting mines and manufactures, taking advantage of our many years of experience that we were previously involved in the development of mines.  Currently, we have established an office in Qingdao, China and managed the mines and productions.  We also respond to the China risk that has been reported recently, and use Graphite of South Africa etc. other than China.  We also provide guidance on mine development to developing countries.

Product Sales

Taking advantage of our long experiences, we select products and manufacturers by evaluating whether they have high quality, stable supply, cost-assessed, and we introduce them that satisfy our customers.  For Natural Graphite, we established an office in Qingdao, China in 2014, and are striving to provide more quickly and carefully services.  We also provide state-of-the-art Graphene, CNT, CF, etc., and offer products that meet the various needs of our customers.

Joint Research and Development

We have collaborated with universities, “Industry-University collaboration”, except for our own development projects with market research, or development requested by customers.  In recent years, we have been working with customers to develop products that can be used in new fields with designing carbon particles which is easy to compound into each resin, or examining oxidant of Expandable Graphite and the treatment methods.


Properties of Graphite


Graphite has excellent heat dissipation, electrical conductivity, lubricity, thermal resistance, and chemical resistance.  Utilizing these properties, it has been used for a long time in the industries of automobile, building material, semiconductor, and steel.
