  • Location: 12 Nakamachi, Muroran City, Hokkaido, 050-8550, Japan
  • Coordinates (WGS 84): 42.341873, 140.997803 (exact)

Background

The Muroran Works was founded in 1909. One blast furnace at the plant was closed in 1982 during the Second Modernisation Plan across the company, and another in 1987 during the Fourth Modernisation Plan.[1] The plant closed one more blast furnace In April 2022, the Nippon Muroran Works steel plant will be renamed to North Nippon Works (Muroran).[2] In 2022, Muroran Works and East Nippon Works Kamaishi Area were reorganized to become North Nippon Works.[3]
