In 2023, the import value of marble, travertine, and ecaussine to Japan was notably lower, setting the stage for a forecasted decline from 2024 through 2028. From 2024, with an initial rise to $1.6188 million, the trend shows a consistent year-on-year decrease in import values, culminating in a projected $0.55447 million by 2028. This represents a clear downward CAGR over the five-year forecast period.

Future trends to watch for include:

Potential shifts in domestic construction demand which might influence import levels.
Changes in global supply chain dynamics and regulations impacting importation costs.
Emerging competitive materials that could substitute traditional stone imports.
