Greeting from President


Since our establishment in 1990, we have been consistently engaged in the development and sales of EMC (Electromagnetic Compatibility) test equipment and systems. In the 1980s, at the dawn of EMC in Japan, I remember with nostalgia the process of building “open test sites” in remote mountainous areas, manually operating antennas, turntables, and electric field strength meters, and tapping calculators to obtain measurement results, as was common practice. The experiences and innovations of those days have become the foundation of our current automatic measurement software development, and I feel that we are truly learning from the past. We have delivered more than 2,500 EMC systems, and we believe this is due to the belief of all our employees that we must listen carefully to our customers’ opinions and realize the desired performance at any cost, without being bound by stereotypes. We will continuously devise ways to contribute to the development of electronics technology, which will continue to increase in speed and capacity in the future.
