In 2023, Japan's imports of human-edible molluscs flours, meals, and pellets stood at a markedly high value. The forecast for 2024 is $986.19 million, with a consistent decline each year, reaching $860.94 million by 2028. This represents a year-on-year decrease in value of roughly 3.2% from 2024 to 2025. The ongoing decline pattern is even more pronounced when assessed over the 5-year period, with a compound annual growth rate (CAGR) depicting a downward trajectory.

Future trends to monitor include:

Potential shifts in consumer preferences towards alternative proteins could exacerbate the decline.
Economic policies in Japan affecting import tariffs or trade agreements affecting mollusc-related products.
Sustainability drives in aquaculture and mollusc farming might impact supply and pricing.
