Japan Heavy Industry measured 28.7 million metric tons of output on a recent production pulse, with steel remaining the anchor of that scale. In the same period, energy intensity improved to 18.5 GJ per ton while crude steel slipped 3.1% as global demand shifted. That mix of efficiency gains, softer volumes, and changing workforce pressure frames what the sector built and what it had to redesign.
