FX.co ★ Japan’s Producer Inflation Eases Slightly in January, PPI Slips to 2.3% YoY

Japan’s producer price inflation cooled modestly at the start of 2026, with the Producer Price Index (PPI) rising 2.3% year-over-year in January, down from 2.4% in December 2025. The latest data, updated on 11 February 2026, reflects a slight easing in upstream price pressures facing Japanese businesses.

The figures are based on a year-over-year comparison, measuring January 2026 prices against those of January a year earlier, while the previous reading compared December 2025 with December of the prior year. The marginal decline suggests that while cost pressures remain present in Japan’s corporate sector, they are not accelerating, providing a cautiously stabilizing backdrop for pricing dynamics in the broader economy.

For policymakers and market participants, the softer PPI reading may signal that pipeline inflation is leveling off, an important consideration for future decisions on monetary and fiscal conditions, as well as corporate pricing strategies.
