Automotive

As times change, so do cars.
We are entering an era where driving is no longer a necessity, energy sources are evolving, and vehicles are becoming interconnected.
As new concepts of automobiles emerge around the world, we ask ourselves: what can we do?

Nippon Steel is committed to mastering "steel," a material of the future with infinite possibilities, and contributing to the realization of a carbon-neutral society.
We continuously advance not only materials but also design and processing technologies, offering comprehensive solutions for the cars of tomorrow.
We envision not just the vehicles themselves, but also the lives of those who ride in them, the cities they drive through, the global environment, and the entire future surrounding automobiles—and we design that future together.
We believe it is our mission to remain a trusted partner in this journey.
