Company Profile

I am greatly honored to have the opportunity to address this message to our customers.
The company dates back to 1901, when gypsum began to be extracted from the Yoshino mine in Yamagata prefecture in Japan. Since then, the company has devoted itself to the gypsum industry.
Yoshino Gypsum's main product is non-combustible building material "Tiger Board" (plasterboard). Our sales network directly connected with major sales agents throughout Japan have enabled the company to always lead the stable development of the gypsum industry.
Plasterboard was invented in the United States about a century ago. Twenty years later, Yoshino Gypsum imported the most advanced technology and began producing the first plasterboard with a brand name "Tiger Board" in Japan.
Since then, the company has done research and development independently on by-product gypsum (synthetic gypsum) such as desulfogypsum generated through flue gas desulfurization in power plants because Japan has little gypsum reserves. These R&D has enabled us to accumulate a vast amount of valuable technological know-how regarding the effective use of gypsum.
The company's technology now ranks at the highest level in the world. It has forged cross-licensing agreements with the world's most famous companies in the United States, European countries and Australia. We are willing to contribute to the creation of a safe and comfortable living environment. We are determined that Yoshino Gypsum has a goal to contribute to the efficient use of natural resources and energy and also to the conservation of global environment.
