Management Philosophy. The compass guiding our journey


Nippon Koei Mobility is guided by ID&E Holdings’ management philosophy of acting with integrity and contributing to society through technology and engineering.

Establishment in 1946, the ID&E Group has been at the forefront of constructing essential social infrastructure, both in Japan and internationally.

The founder of ID&E, Yutaka Kubota, boldly declared, ‘Tackle your problems with sincerity, and the road ahead shall be clear.’ He dedicated his technical expertise and passion to the creation of social infrastructure that is not only safe but also reliable. This ethos of social contribution, rooted in conducting business with conviction, is an integral part of our corporate DNA, guiding our employees to this day.

In a world where many aspire to higher living standards, the ID&E Group remains steadfast in its commitment to acting with integrity. We continue to contribute to national and regional social development worldwide.
