History until Our Debut

We want to create products that will be used world-wide.
However, there are costs involved in developing something from scratch, including massive equipment investment costs.
So, if we could change how products and machines recognized in Japan for having outstanding results are used and made, then maybe we can reduce testing and machine investment costs while still succeeding in manufacturing.
Based on this concept, we searched for products that, despite their high performance, were hard to sell due to their high price and looked for ways to manufacture them cheaply.


The little gem that we found was Japanese paper infused with carbon fibers.
Traditional Japanese paper has particularly longer fibers than that of Western paper. This creates a strong, thin paper that for over 1,000 years has epitomized long life and durability.
This product can be heated up to 300°C, so the heat it produces can be used in heating floors, hospital beds, etc.


Taiyo is entirely focused on the intrinsic thinness, light weight, workability, and heat generative abilities of this paper.
Can we process this paper so it can be used on rooftops? At a considerably low cost?
Despite being confronted with various issues, we succeeded in the sheet being used for road heating, agricultural seed raising, and rooftops.
Agricultural applications and road heating are two areas where equipment investment will be vital as the population declines. They are major global issues.


Of course, Japanese paper is still paper. Japan takes pride in its technology to process paper.
But in today’s paperless age, people are using less paper and there are fewer chances to manufacture using this excellent technology and machinery.
So we commissioned manufacturing to a printing company so we would not have to make the investment necessary for manufacturing while still creating an inexpensive, high performance product.


Today, TAIYO SHEET is being used in a variety of fields, including Metropolitan Expressway, on farms, and on golf course cart paths.
While making use of the excellence of Japanese paper and printing technology now more than ever,


we are confident that TAIYO SHEET will help with global infrastructure (road) maintenance and farm crop cultivation, and be useful worldwide.
