Japan approved its 2025 agricultural white paper on May 29, saying the
government underestimated domestic rice supply-demand and did not promptly
release reserve rice, contributing to a price surge that began in summer 2024.
The paper said officials assumed population decline would lower rice demand and
therefore did not actively monitor market circulation. Panic buying over
earthquake risk and heat-related poor harvests also helped push prices higher.
Rice commodity prices rose 67.5% in 2024, the largest increase since comparable
data began in 1971; average supermarket 5 kg retail prices exceeded 4,000 yen
(about 170 yuan).
