Company information
Our company was founded in 1949 as a designated manufacturer of wire materials for the Ministry of Telecommunications. We have steadily established our presence by designing and manufacturing telephone and communication systems and related equipment for public enterprises such as police, railways, electricity, and broadcasting, alongside the development of related companies. We also have a significant track record in OEM products for major manufacturers. Our main products are custom-made items, which we handle from design to manufacturing, focusing on systems and products related to information and communication. Recent key products include disaster prevention information systems (JR East and JR Hokkaido), command telephone systems (various JR companies, electricity companies, and private broadcasters), remote monitoring and control systems (various JR companies, electricity companies, and telecommunications carriers), and emergency contact systems (private elementary and middle schools). Currently, we are working on the development of the latest IT and IP systems, such as serverless IP conference call systems, to adapt to the evolution of communication networks. If you present us with challenges in niche areas where major manufacturers are not proficient, we are committed to responding with low prices and short delivery times by leveraging the experience we have accumulated over many years and the latest technology. We appreciate your guidance and encouragement.
