Background

Nakayama Steel Works Ltd. established the Funamachi plant in 1929. The plant discontinued its blast furnace, sintering plant and basic oxygen converters in 2002 and has only been operating its electric arc furnace-based steel production. In February 2022, Nakayama Steel Works announced its plan to expand its EAF-based steel capacity at the site originally occupied by the retired blast furnace and coking plant. In 2023 the site was cleared for construction and in 2024 the feasibility assessment of the development is in process
