FX.co ★ Japan’s Reuters Tankan Index Climbs to 21 in September, Signaling Stronger Business Sentiment

Japan’s corporate mood improved in September 2026, with the Reuters Tankan Index rising to 21, up from 18 in August 2026. The latest reading, updated on 8 September 2026, points to strengthening business sentiment among Japanese firms.

The three-point increase suggests that companies are feeling more confident about the economic outlook compared with the previous month.

The September 2026 reading at 21 may be interpreted as a modest but notable reinforcement of optimism in Japan’s business environment.
