What emerges
See the company through the numbers →HOYA’s mask blanks enter semiconductor circuit-patterning processes; its HDD glass substrates become the bases of magnetic disks. The company emphasizes customer-specific technical alignment in the first business and consistent high-volume production in the second. Revenue was ¥947.7bn in the year ended March 2026, with a company-reported mix of 62% Life Care and 38% Information Technology. Supplying lenses to optical retailers and operating Eyecity stores are also important parts of the group. Initial-phase investment in two new EUV and HDD plants is planned at roughly ¥92bn combined. Looking at customer processes and supply requirements helps explain the strengths of the businesses that expanded from optical glass.
