Electron tubes are used in numerous fields from industrial heating through social infrastructure such as broadcasting, communications and weather observation radars, and even in nuclear fusion and high energy research.

In the field of industrial heating, we have a wide range of products such as power grid tubes and magnetrons appropriate for various applications.

In the fields of communications and nuclear power, we consistently produce continuous wave magnetrons, neutron detectors and other products that offer world top-class reliability.

In the field of advanced science and technology, we have been developing gyrotrons and super high-power klystrons with world-leading performance by integrating technologies arising from joint studies conducted by Japanese and international universities and research institutes.
