Nippon Stainless Steel Yamaguchi Works (Shunan Area) steel plant, also known as Shunan Area Yamaguchi Works, is a steel plant in Shunan, Yamaguchi, Japan that operates electric arc furnace (EAF) technology.
Location
The map below shows the exact location of the plant in Shunan, Yamaguchi, Japan:
- Location: 4976 Nomuraminami-machi, 746-8666
- Coordinates (WGS 84): 34.059009, 131.777221 (exact)
Background
Nippon Stainless Steel Co. Ltd (NSSC) was launched as the largest general stainless steel manufacturer in Japan following the integration of a part of the steel sheet business contained within the special stainless steel business of the former Nippon Steel & Sumitomo Metal Corporation, the steel sheet business contained within the stainless steel business (steel sheets, steel pipes, and tubes) of the former Nisshin Steel Co., Ltd., and the former Nippon Steel & Sumikin Stainless Steel Corporation.[1] In October 2024, Nippon Steel Corporation (NSC) and NSSC, a wholly owned subsidiary of NSC, announced their merger with NSC as the surviving company and NSSC as the dissolving company, effective as of April 1, 2025.[2]
Nippon Stainless Steel Yamaguchi Works (Shunan Area) was established in 1958.[3] The plant operated three electric arc furnaces (EAF) with a combined capacity of 1300 thousand tonnes per annum (ttpa).[4][5] One of the EAFs was idled since March 2024. However, as of November 2024, the company is seeking government support under the GX promotion act to upgrade and restart the furnace.[5][6]
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, converting from BF-BOF to EAF at Yawata, and restarting EAF operations at Shunan.[7] The EAF furnace at this plant is set to restart in the second half of the fiscal year 2028.[8]
