Our company mainly manufactures broadcast and radio equipment, semiconductor and LCD manufacturing equipment, and information and communications equipment. Many of our products support the foundations of life in society. We are proud of manufacturing these products and take pride in our contributions to society. There should be a vortex of innovation involving domestic and overseas sites to continue and grow Japanese-style Monozukuri craftsmanship in the future.
