In addition to the construction of NAYUTA, Mitsubishi Electric has been an integral force behind the development of SUBARU, the world's largest telescope, in Hawaii, as well as other optical and radio telescopes, some of which are introduced here.

Making full use of state-of-the-art technologies, Mitsubishi Electric has successfully built and delivered a number of telescopes, including the large optical infrared telescope SUBARU in Hawaii, and a 45-meter large cosmic radio telescope in Nobeyama, Japan. By observing and detecting visible light, infrared light, and radio waves emitted from space, these telescopes play an important role in revealing the mysteries of the universe.
