In 2023, Japan's import of ash or residues containing mainly copper stood at a certain baseline level, which transitioned into a forecasted decrease over the subsequent years. Between 2024 and 2028, a steady decline is observed, with a slight year-on-year decrease averaging around 2% per annum. By 2028, this gives a cumulative decrease driven by various external factors potentially affecting the import quantity.

Future trends to watch for include:

Global demand fluctuations for copper due to technological advances.
Evolving Japanese environmental policies impacting import levels.
Market dynamics influenced by changes in copper production and recycling efficiencies.
Potential geopolitical factors affecting trade relations with source countries.
