To contribute to maintenance and management of infrastructures worldwide
Nitto construction aims not only contribute to the development of infrastructures of the local society as a general contractor, but also create new technologies to bring innovation to the construction industry. We established NDT division to expand our business in 2000. From 2003, we started to develop a Non-destructive testing equipment called Concrete Tester (CTS) that can evaluate the compressive strength, degree of degradation and delamination for concrete structures, and released in 2005. In addition to that, BOLT-Tester (BTS) for Non-destructive testing of bolts and nuts was released in 2014.

We promote these product worldwide such as the US, South Korea, Taiwan, Singapore and Nigeria not only in Japan. We are awarded The Monozukuri (Craftsmanship) Nippon Grand Award (Special Award) in 2009 and Local Commendation for Invention of Hokkaido (Prize of Director-General, Small and Medium sized Enterprises) in 2010. We are sincerely grateful to be supported by everyone work with us.

We will continue to improve and develop new technologies, and become a technology-oriented construction company.
We will greatly appreciate your further cooperation and encouragement.
