iyama Industry Corporation wRH


The development of the IT industry in recent years has spurred remarkable growth in our environment. The technological abilities and quality of overseas production industries have increased, and Japanese industries now must establish technologies that can compete with overseas production systems. We at Hiyama are using our technical prowess and facilities to pursue the development of technologies that can be applied to production.
We are also working to create a system for pioneering new fields. The combined efforts of our employees are creating great energy and capabilities.
What can we do? What do we want to do?
We want to be a company on the world stage that can synergize the energies of all group companies in Japan and overseas as one cohesive force.



Photonics Devices

Fiber arrays
Fiber arrays are essential components for current large-capacity and high-speed communication networks. Over the past 20 years HIYAMA has been a pioneer in the development of a mass-production system of fiber arrays, including V-groove processing, fiber assembly, polishing and inspection.

Advancements in digital equipment have been brought about by technological innovations such as high functionality and miniaturization. This has enabled high-density mounting and highly intricate processing of electronic boards, which has been supported by extremely advanced processing technology, We at Hiyama are constantly improving technology, training staff and introducing the latest equipment. We are winning acclaim for our extremely high-level slitting technology and rigorous quality control. Using the most advanced clean rooms, we are processing cutting-edge materials, such as those used for producing electronic parts, separators for lithium-ion batteries.



Touch panels used in various places play a major role in the advancement of digital equipment. Functional films and polarizing films are important components for supporting touch panels displays. Hiyama's high technology and new and powerful automated lines are used to process these films. Hiyama also processes films for protecting all sorts of materials such as glass, metal and plastic, adhesive coatings for high-definition electronic equipment. In addition, with the introduction of a high-performance pilot unit, it has becom possible to apply laminate processing to materials regardless of their thickness.
