In 2023, the share of road infrastructure maintenance in Japan’s total road infrastructure spending stood at 42.1%. From 2024, forecasts suggest a steady increase in this share, rising from 42.88% to 46.21% by 2028. These projections indicate a consistent year-on-year growth, marking a trend of increasing emphasis on maintenance activities within the overall road infrastructure budget.

The average compound annual growth rate (CAGR) over this five-year forecast period is approximately 1.81%. This upward trend highlights a growing prioritization of maintaining existing road infrastructure as opposed to new developments, likely in response to aging infrastructure concerns.

Future Trends to Watch:

Increased technological integration for maintenance efficiency and cost reduction.
Policy shifts focusing on sustainability could influence spending priorities.
Demographic changes impacting road usage patterns and maintenance frequency.
