FX.co ★ Japan’s Tertiary Industry Activity Surges in December, Rebounding from November Slump

Japan’s services sector posted a sharp rebound in December 2025, with the Tertiary Industry Activity Index jumping to 8.40 after a steep decline to -2.50 in November 2025. The latest figures, updated on 17 February 2026, signal a strong turnaround in activity across the country’s service industries.

The swing from a negative reading in November to a robust positive level in December suggests a rapid recovery in demand in areas such as retail, transport, finance, and other service-related fields that make up Japan’s tertiary sector. While the data do not provide detail on the specific drivers, the magnitude of the move highlights a notable shift in momentum at the end of 2025.

This reversal in the index will likely be watched closely by market participants and policymakers, as the tertiary industry is a key pillar of Japan’s economy and a major contributor to overall growth dynamics going into 2026.
