About NAGAOKA

Message from the President

Carrying Forward Our Technology to Create New Value.

We would like to express our sincere gratitude for your continued support of NAGAOKA Co., Ltd. and the NAGAOKA Group.

Our history of manufacturing began in 1940. Building on expertise cultivated through the production of watch components and gemstone processing, we have expanded our business in response to the needs of each era, developing record styli, cartridges, diamond tools, terminals for measuring instruments, magnet components, and more.

Among our most important assets is the technology we have refined over many years for processing hard and brittle materials--including diamond, sapphire, cemented carbide, and ceramics--to exceptionally fine tolerances.

This expertise is supported not by equipment and machinery alone, but by the experience and inquisitive spirit of each engineer who recognizes subtle differences in materials and completes the work by relying on sound, vibration, and fingertip sensitivity. We believe our mission is not only to preserve the skills we have inherited, but also to pass them on to the next generation and develop them into new products and new value.

Even in today's increasingly digital world, the importance of analog technology grounded in human sensitivity and meticulous craftsmanship remains unchanged. The same precise, often invisible expertise lives in both the stylus tip that retrieves music from a record groove and the microscopic components that support advanced industries.

We will continue to listen sincerely to our customers, uphold our responsibility for quality, and respond flexibly to changes in society and the market. As a company that supports both the joy of music and the future of manufacturing, we will strive to remain a trusted partner in Japan and around the world.

We sincerely appreciate your continued support of the NAGAOKA Group.
