Our Business
As one of Japan's leading general manufacturers of precious metal products, we operate a comprehensive business that encompasses development, manufacturing, sales and recycling of precious metal materials, products, and technologies.
Product Development and Manufacturing
One of our main distinguishing features is the way we concentrate the operations of R&D, production technology, manufacturing, quality assurance, and other functions at the Soka Plant. We have established a flexible and agile production system through seamless collaboration among individuals, materials and information across departmental boundaries within the plant.
Sales
The sales representatives at the Tokyo headquarters and branches in Nagoya, Osaka and Fukuoka serve as contact points for clients. They handle a wide range of clients' questions and concerns regarding quotation, order, prototyping, recycling, etc.. We welcome inquiries and consultations from new clients, so please feel free to contact us.
Refining and Recycling
We carefully select the best methods for separation, recovery, and refining of chemically stable precious metals that do not melt easily. Refined to high levels of purity, these precious metals are used as raw materials for new products. We also recycle scrap generated in production processes, so that rare precious metals can be utilized without waste.

Precious metal bullion
Our gold, silver, and platinum bullion have been certified by London Bullion Market Association (LBMA) and London Platinum and Palladium Market (LPPM). Leveraging our expertise in manufacturing high-purity precious metal, we produce not only industrial products but also bullion for investment.
Refining and Recycling
We consider that the recycling side of our business plays an important role in ensuring sustainable use of rare and expensive precious metals. We choose the best methods to recover and refine precious metals from items of clients. After refining, we can either purchase the recovered precious metals or return them to you, depending on your preference. Alternatively, we can use the recovered precious metals to create new products for you.
