In 2023, the import of poles treated or painted with preservatives to Japan stood at 338.75 cubic meters. The forecast from 2024 to 2028 suggests a steady decline in import volumes, with yearly reductions ranging from approximately 6.95% to 8.95% year-on-year. The compound annual growth rate (CAGR) over these five years is around -7.13%, indicating a consistent downward trend in import volume. This decline may be attributed to factors such as increasing local production, a shift towards alternative materials, or changes in demand.

Future trends to watch for include:

Potential shifts in domestic and international regulations impacting import volumes.
Technological advancements leading to different treatment methods and their acceptance in the market.
Changes in consumer preferences and environmental policies influencing the demand for sustainable materials.
