Location
The map below shows the exact location of the plant in Tahara, Aichi, Japan:
- Location: 2-1-3, Shirahama, Tahara-shi, Aichi 441-3436, Japan
- Coordinates (WGS 84): 34.702012, 137.249114 (exact)
Background
In 2007, Tokyo Steel completed acquisition of land for Tahara factory and started construction of new factory.[1] As of 2014, the 420-tonne electric arc furnace (EAF) at Tokyo Steel Tahara is the largest EAF in the world.[2]
In 2024, Tokyo Steel started its new proprietary green steel brand called "Ensō".[3]
In line with Japan's commitment to achieve carbon neutrality by 2050, Tokyo Steel announced its long-term environmental vision "Tokyo Steel EcoVision 2050". Tokyo Steel aims to reduce CO2 emissions by 60% by 2030 and by 100% by 2050 from emissions levels as of fiscal year 2013.[4]
On May 25, 2025, an explosion occurred leading to a temporary suspension of operations.[5]
