Our company was founded in the welding and machining of automotive parts, and the most difficult part of a repair project is to determine the cause of the defect. The problem with the product we receive is not always in one location or one part. There may be multiple causes, and they may be intricately intertwined.
Our company's fundamental stance is to pursue other defects even after we find a defect. This has been true not only in our repair-related business, but in all of our 75-year history. This attitude has been recognized by many customers in a wide range of industries and has continued to this day.

Our business with a wide range of industries, including aircraft, construction machinery, ships, and automobiles, provides us with an environment in which we can constantly inherit and improve our skills and technologies. In addition, we are able to deliver stable services because our entire business partners are not affected at the same time by global depression or pandemics such as coronavirus.

Our first step in the aircraft ground support equipment (GSE) business was when an airline company was looking for a company that could be entrusted with integrated manufacturing from design to production. With this as an opportunity, we have received numerous orders for manufacturing from aviation-related companies and government agencies for nearly 60 years. Furthermore, we have acquired ISO9001 and JISQ9100 certification to ensure thorough quality control. Our technical capabilities have transcended the industry and have earned us a high level of trust.

We have three bases: Tokyo Head Office (Ebisu, Shibuya-ku, Tokyo), Tokai Sales Office (Obu City, Aichi Prefecture), and Narita Plant (Narita City, Chiba Prefecture). Our footwork allows us to expand the scope of our activities nationwide and respond to urgent problems. We have built a system that can respond to changes in market needs in the transition from the "mass production era" to the "multiple-product, variable-mix, variable-volume era.
