President Takayuki Yamaguchi

Since our founding in 1957, our goal at Non-Destructive Inspection Company Limited has been to act as the defenders of safety, using non-destructive inspection technology to protect the safety of society, and to provide safety-related technology services that incorporate our corporate ideas, techniques, and philosophy. These last 60 years have only been possible thanks to our customers, and for that, we are truly grateful.

Across Japan, consolidation and reorganization of plants have progressed in step with a changing society--particularly with an increased focus on energy-related issues--and with that the overall aging of social infrastructure has become a major concern. As our name suggests, we are aware of the growing expectations of non-destructive testing, and we continue to do our best to develop new technologies and improve our quality and services in order to best respond to any and all customer requests.

At Non-Destructive Inspection Technology Company Limited, we strive to be a group of technicians that cherishes safety and the value of people and things while also harboring the clarity required to recognize the merits and limitations of all things. We look forward to your support and guidance in this endeavor.
