Background

The Nippon Setouchi Works (Hirohata Area) steel plant began operating in 1939.[1] It previously had 3 basic oxygen furnaces, but they were shut down.[1] A 2300 ttpa electric arc furnace expansion is in the works, with a completion date of 2022.[1]

In 2023, the company announced another EAF addition to the plant. The details of the same are not known.[2]

Nippon Steel in 2025 announced plans to invest a total of JPY866.7 (around USD 6.0 billion) billion by 2029, supported by up to JPY251.4 billion (around USD 1.7 billion) in government subsidies. Projects include expanding EAF capacity at Setouchi Works by 500 ttpa, converting from BF-BOF to EAF at Yawata, and restarting EAF operations at Shunan.[3] The EAF furnace at this plant is scheduled to commence production in the second half of the fiscal year 2029.[4]
