No.1 in flight data recorder market share in Japan

We were founded in 1952 as a repair service provider for aeronautical instruments.
Since then, we have expanded our product lineup to include flight data recorders (FDR), for which we hold the highest market share in Japan, in the pursuit of advanced technologies and high quality.
We have built a strong track record in the field of land, sea and air defense.
Armed with the technology and quality we have cultivated over many years, we will continue to aim for further growth and development.
