1.1 Corporate Foundation

4

Hitachi was founded in 1910 as a machine repair shop at Kuhara Cupper Mining Company in Hitachi City, Ibaraki Prefecture, Japan

Mine development requires building of houses for employees, schools, hospitals and infrastructure to support the life of the residents.

Hitachi has been deeply involved into urban development since its very foundation, and has contributed the development of infrastructure of Japan throughout its history of 101 years.

Corporate credo: Contribute to society through the development of superior, original technologies and products

Hitachi founding spirit: Harmony, Sincerity and Pioneering Spirit

Founder Namihei Odaira

Original repair shop in Ibaraki (1910)
