Background
Nakayama Steel Works Ltd. established the Funamachi plant in 1929.[1] 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.[2] 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[3]
Nippon Steel and Nakayama Steel announced their plan to enter into a joint venture to establish a 1.2 mtpa EAF at the Funamachi plant with a total investment of JPY 9.5 billion. Nakayama Steel will hold 51% of the venture, and Nippon Steel 49%. The joint venture will be established in March 2026, with construction starting in August 2026 and operations set to begin in 2030.[4] Nakayama Steel will manufacture slabs using that EAF. Nippon Steel will purchase a portion of those slabs, or will commission Nakayama Steel to perform additional processes of rolling and otherwise processing slabs and then purchase the processed hot-rolled coils and other products from Nakayama Steel.[5]
