In 2023, the import of phosphorus to Japan stood at approximately 24 million kilograms. From 2024 onwards, forecasts indicate a gradual increase in import volumes, reaching around 25.363 million kilograms by 2028. The year-on-year growth rate demonstrates steady improvement, with a consistent rise of about 0.8% annually over the five-year forecast, resulting in a compound annual growth rate (CAGR) suggesting a stable but slight upward trend.

Future trends to watch include:

Potential shifts in global phosphorus supply and demand dynamics, influenced by international trade policies.
Environmental regulations impacting phosphorus usage and sourcing in Japan.
Advancements in phosphorus recycling and substitution affecting import dependencies.
