As of 2023, Japan's import of pebbles, gravel, broken and crushed stone for aggregate stood at a recorded figure, with a forecasted decline from 2024 through 2028. Over this period, we anticipate a continual decrease in import values, with specific year-on-year declines observed across the span. The compound annual growth rate (CAGR) over these five years reflects a downward trend, indicating a consistent reduction in imports each year.

Future trends to watch for include:

Potential shifts in domestic production capabilities that could further reduce demand for imports.
Environmental regulations that might impact both the supply chain and usage of these materials.
Infrastructure and construction demands that could alter import requirements.
Fluctuations in global economic conditions influencing market dynamics and pricing.
