Major Japanese convenience store chains are lowering the retail prices of various onigiri products by 10 to 22 yen per item [1, 2, 3].
This shift comes as a relief to consumers facing high food costs, signaling a rare price reduction in the retail sector driven by a surplus of domestic rice supplies.
The price cuts are being implemented across nationwide networks at different intervals. FamilyMart began reductions during the week of Aug. 24 [1]. 7-Eleven will lower prices starting Sept. 8, with items such as charcoal-grilled silver salmon and spicy cod roe dropping from 232 yen to 213 yen [1]. Lawson will reduce the price of 20 hand-rolled onigiri items by 10 to 11 yen each starting Sept. 29 [1].
Specific Lawson price changes include the tuna mayonnaise onigiri dropping from 181 yen to 171 yen, and the aged Kishu Nanko plum variety moving from 194 yen to 184 yen [1]. The aged grilled red salmon will also drop from 221 yen to 211 yen [1]. Additionally, a pilot program at Lawson Store 100 began on April 15, reducing certain items from 130 yen to 108 yen [3].
FamilyMart is implementing larger cuts for some products, such as its large kelp and tuna mayonnaise onigiri, which will drop from 320 yen to 298 yen [1].
The pricing adjustments follow a period of high volatility in the rice market. The Ministry of Agriculture, Forestry and Fisheries said that inter-dealer rice prices in July were more than 10% lower than the peak seen in October 2026 [4]. This decline was fueled by private-sector rice inventories reaching a historic maximum at the end of June [1].
Retailers are using these lower wholesale costs to attract more customers. A Lawson spokesperson said the company wants to lead to an expansion of rice consumption [1].
“Lawson, FamilyMart, and 7-Eleven are lowering rice-ball prices following a drop in wholesale rice costs.”
The price reductions reflect a correction in the Japanese rice market after a period of scarcity and peak pricing in late 2026. By passing these savings to consumers, convenience store chains are not only reacting to a record-high surplus of private-sector inventory but are strategically attempting to reverse a trend of declining rice consumption among the Japanese public.
