In 2023, the number of cards with a debit function per inhabitant in Japan stood at 3.61. The forecasted data indicates a gradual increase from 3.63 in 2024 to 3.70 in 2028.

The year-on-year percentage variation illustrates a consistent growth pattern. The compound annual growth rate (CAGR) for the forecasted period (2024-2028) is minimal, reflecting a stable, albeit slow, increase in debit card usage per inhabitant.

Future Trends to Watch:

Continued digital payment penetration and the effect of fintech innovations on consumer behavior.
The impact of demographic changes, particularly aging population dynamics, on debit card adoption.
Government policies encouraging cashless transactions, possibly accelerating this trend.
