  2. Company Profile

Nippon Yttrium Co., Ltd. (NYC) is a comprehensive manufacturer/supplier of rare earths, providing integrated services from refining to sales.
Using the solvent extraction method and the ion exchange method, we are one of the first companies to mass-produce high-purity rare earth products. Today, rare earths are not only used in many electronic products, but also in a wide range of industrial fields, from energy to medicine and semiconductors.

Corporate Philosophy

To contribute to the society through the continuous creation of high-quality rare earth products, and to seek an eternal growth of the company.

Message from the President

To continue to provide rare earth products that society needs,
To continue to be a company that people need,

Since its establishment in 1966, Nippon Yttrium Co., Ltd. (NYC) has focused on the development of new rare earth products and their stable supply in order to meet the demands of society.
In its early days, NYC focused mainly on yttrium products. Over the past half century, however, it has developed into a "comprehensive manufacturer of rare earths" that handles all ranges of rare earth products.
NYC manufactures well over 300 types of products, including extremely high-purity rare earth compounds made by solvent extraction technology, various oxide powders and granules made by advanced physical property control technology, composite oxides with other elements, rare earth salts, and pure rare earth metals and alloys.
We also have a dedicated team that specializes in the development of new products and works closely together with our customers to meet their needs.
Up until now, we have never stood still, but have actively pursued the development of materials and innovative mass-production technologies, looking ahead to the trends of the times.
At the root of our efforts is our strong passion for developing materials that meet the needs of our customers. This is the "NYC Spirit" that we have inherited since our founding.

We will continue to listen to the voices of our customers, and as rare earth professionals, we will do our utmost to meet the expectations of our customers.

We sincerely ask all of you for your continued guidance and encouragement.
