Japan’s industrial production posted a sharp month‑on‑month acceleration in January 2026, with output rising 4.3% compared with a 2.2% increase previously recorded. The data, updated on 19 March 2026, signal a notable strengthening in manufacturing and industrial activity at the start of the year.
On a month‑over‑month basis, the latest figure shows that January’s production growth almost doubled relative to the prior comparison, when industrial output had grown 2.2% from the preceding month. The “actual” January reading (4.3%) reflects the change versus December, while the “previous” figure (2.2%) captures the change in the earlier month versus its prior month.
The robust January performance suggests a firming of short‑term industrial momentum in Japan, an important gauge for tracking near‑term growth and business cycle dynamics in Asia’s second‑largest economy.
