In 2023, household expenditure on tuna fish in Japan was approximately 3.82 thousand yen. Forecasts indicate a gradual decline from 2024 to 2028, with expenditure dropping from 3.75 to 3.49 thousand yen. This reflects a consistent negative year-on-year variation, signaling a steadily decreasing trend. The compound annual growth rate (CAGR) over the forecasted five-year period is negative, indicating an average yearly decrease in spending.

Future Trends to Watch:

Impact of changing consumer preferences towards alternative seafood options or plant-based diets.
Potential influence of sustainability and environmental concerns affecting tuna consumption.
Price fluctuations driven by fishing regulations, supply chain disruptions, or global demand changes.
