Precision molded resin part for a hard disk drive.

When you see the lineup of Yamauchi products, you may be surprised by its wide variation. Yamauchi offers everything from resin parts for hard disk drives as small as 2 mm in diameter, to papermaking rolls up to 11 m in length. All of our products offer advanced functions that were made possible by Yamauchi’s unparalleled expertise. At Yamauchi, there is no “standard” product. Using original technologies, Yamauchi produces products that provide the specific performance and functions required by each customer. Yamauchi’s expertise has been highly evaluated by leading manufacturers in various fields since the company was founded. Yamauchi develops and supplies products that are offered by no other company in the world. Our corporate strategy says it all: Niche & Global.

The fact that our products have been used in various products in Japan and around the world gives testimony to Yamauchi’s expertise and superior technologies.

Pinch rollers for video cassette recorders and other products.

The Niche & Global strategy is based on our many past successes. One of these was the pinch roller* for video cassette recorders. Offering high quality and high performance thanks to original Yamauchi technologies, this part achieved a worldwide market share of more than 90% in the 1980s. For the paper manufacturing industry, we provide urethane rolls. In 1963, Yamauchi made a papermaking press roll (High Top Roll) from polyurethane for the first time in the world. This made “Yamauchi — The technology-oriented company” known worldwide. Since then, Yamauchi has continuously progressed based on the Niche & Global strategy.
Today, the company provides a stream of products with huge potential for future growth, such as vibration insulation rubber for disk drives, torque limiters for copy machines and banknote verification systems, and high-performance cushioning (YOM, Top Board) for press use.

Product development is a race against time. We have to present prototypes to our customers as soon as possible. We also need to conduct R&D activities to improve product performance and quality in the shortest possible time. Yamauchi conducts various types of R&D in response to diverse customer needs in order to achieve the best results. For example, when we develop parts for a product that must be introduced to market at the most opportune time, such as a disk drive and audio/visual equipment, we use a unique system that we called YQR (Yamauchi Quick Response). For a rubber product to isolate vibration, we can complete a series of processes ranging from computer simulation of the product characteristics to production of molds and delivery of prototypes in only three days. This helps to reduce the customer’s R&D turnaround time. For the paper manufacturing industry and others that require various parameter settings for improving product performance and reliability, we invest ample personnel and time to develop products that far exceed the performance of previous products.

Yamauchi Organizations


Corporate History

  • Yamauchi has built and fostered technologies,customer confidence, and a global network since 1918.

    The history of Yamauchi can be divided roughly into five phases. The first was the “inception period” in which Yamauchi expanded its business in Osaka Prefecture by acquiring companies in the western part of Japan. In the second phase, the “technological development period,” the company focused on developing original products based on composition technology and the development of precision processing technologies that would enhance product functions. In the third phase, the “domestic base expansion period,” the company built factories one after another in Japan to expand its customer-oriented sales network. Yamauchi then established overseas subsidiaries and factories with the aim of achieving global business growth in the fourth phase, the “overseas business expansion period.” In the fifth phase, the “period of challenging global standards,” Yamauchi set out to achieve compliance with ISO, REACH, CSR and other major standards, mainly in China, the ASEAN nations and the European Union. The following milestone events mark each of those periods.
