NDK (Nihon Dempa Kogyo Co., Ltd.) was established in 1948 with a founding philosophy of "contributing to the prosperity of society and world peace through our service to customers." This philosophy is founded on a belief that providing reliable, high-quality and attractive products at an appropriate price can be useful to customers and can, by extension, help society prosper. Moreover, the founder believed that enhancing communication among people through accurate information would promote international understanding as a cornerstone of lasting peace. This belief was generated by the founder, Masamichi Takeuchi, from his experiences of the war. Since its foundation, as a company specializing in the manufacturing of quartz crystal devices for frequency control, selection, and detection, NDK has created various frequencies and has helped electronics develop from inside the devices.
NDK head office is in Tokyo, Japan and production plant in Sayama-city.
