As of 2023, the actual demand for rapeseed and mustard oil in Japan was estimated at 1.02 million metric tons. Forecasts suggest a stable demand from 2024 to 2028, with values averaging around 1.03 million metric tons in the early years and slightly decreasing to 1.02 million metric tons by 2027-2028. The year-on-year variation indicates a stable trend with a minor anticipated decline towards the end of the period. The overall compound annual growth rate (CAGR) over the 5-year forecast period is nearly flat, suggesting negligible growth.

Future trends to watch for include:

Changes in consumer health preferences, potentially impacting demand for vegetable oils.
Supply chain fluctuations, particularly in response to global agricultural practices.
Economic factors and policy changes in Japan affecting import and production of oils.
