Creating a bright and people-focused future
throughinnovative technology.
President Yoshihisa Hagihara
River Eletec is an electronic components manufacturer engaged in the development, production, and sales of crystal devices—essential timing components that power virtually all electronic equipment. Guided by our corporate principle of “High Quality, Competitive Pricing, and Quick Delivery,” we place customer satisfaction and trust at the heart of everything we do, continuously creating value and driving innovation.
Founded in 1949 as a manufacturer and distributor of resistors, we have consistently pursued original and creative manufacturing—an approach that forms the DNA of River Eletec. Since launching our crystal business in the late 1970s, we have built extensive expertise as a leading company in the miniaturization of crystal devices. As a result, we have earned strong customer confidence, often recognized as the go-to provider for compact solutions. In recent years, we have achieved one of the world’s leading market shares in ultra-compact tuning-fork crystal units used in smartphones and IoT devices, contributing to smaller, thinner, and more energy-efficient electronics.
The foundation of our strength lies in our people and a culture of mutual learning. This has fostered an open, dynamic workplace characterized by healthy tension, strong collaboration across all levels, and exceptional execution capabilities. By integrating sales, development, and manufacturing as a unified organization, we continue to enhance our collective competitiveness. From this environment have emerged technologies and products that set us apart—such as advanced crystal photolithography processing, proprietary sealing technologies, and the discovery of the new KoT cut crystal element.
In March 2024, we proudly marked our 75th anniversary. While society and business environments continue to evolve, our enduring philosophy remains unchanged: nurturing people, contributing to society, and pursuing original manufacturing excellence. Under our slogan “Connecting to the Future,” we support the advancement of the electronics industry—particularly wireless communications—while striving to create a vibrant, people-focused future. Looking ahead, we remain committed to earning society’s trust and contributing to the resolution of global challenges, including environmental responsibility, quality assurance, human capital development, and diversity, in pursuit of a prosperous and sustainable society.
