Japan's private rice inventories reached a record high in May 2024, contributing to a steady decline in retail prices [1], [2].
This shift in the market signals a period of significant oversupply that could impact farming incomes and national food security strategies. While consumers benefit from lower costs, the surplus highlights a growing gap between production levels and domestic demand.
Private operators held 2.23 million tons of rice at the end of May 2024 [1]. This represents an increase of 740,000 tons compared to the same month the previous year [1]. According to government and industry data, these stockpiles are at their highest level since 2014 [2].
Retail prices at supermarkets across Japan have reacted to the surplus. The average retail price for a five-kg bag of rice fluctuated between 3,644 yen [4] and 3,673 yen [3] during the final weeks of May 2024. Some reports indicate that average prices have continued to slide into the 3,500 yen range [1].
Specific regional price drops have been even more pronounced. For example, five-kg bags of Koshihikari rice from Ibaraki Prefecture cost an average of 3,866 yen in March, but fell to 2,914 yen by June 2 [5].
Market analysts said the price drop and inventory surge are due to several factors. A series of bumper harvests led to an oversupply of grain [1]. Simultaneously, consumers have reduced their purchasing habits [1]. The trend has been further compounded by the restaurant industry's increasing use of imported rice over domestic varieties [1].
Weekly price tracking shows a consistent downward trend. The average price for five-kg bags fell by 19 yen [3] in one reported week and by 29 yen [4] in another, reflecting the pressure on retailers to move excess stock [3], [4].

The convergence of record-high inventories and falling prices suggests a structural imbalance in Japan's rice market. The shift toward imported rice in the food service sector and a general decline in domestic consumption are outpacing the agricultural output of bumper harvests. If this trend persists, the Ministry of Agriculture, Forestry and Fisheries may need to intervene to stabilize prices and protect the livelihoods of domestic farmers.
