Our company provides ultra-precision processing technology that supports optical telecommunications networks. 

Our company was the first in Japan to manufacture watch jewels. We then began to make optical communications connecting components as well as semiconductor- and medical-related parts through the grinding and polishing technologies we gained from watch jewel production. Our main products are ferrules, and we handle all the manufacturing processing entirely in-house from ceramics molding to grinding, polishing, quality assurance, and logistics. Our other lines of business include machining small-diameter parts that make use of ceramics, rubies, sapphires, and so on. These products are shipped to major electrical cable manufacturers and telecommunications device manufacturers in Japan and overseas locations such as North America, Europe, and Asia.
