Japanese food companies Lake and Lotte will raise prices on potato chips and ice cream starting in July and August 2026 [1].
These price hikes reflect a broader trend of inflation hitting the Japanese consumer market as companies struggle to absorb escalating operational costs. The adjustments target popular snack items sold across supermarkets and other retail stores nationwide.
Lake will increase prices for 12 potato chip products starting in August 2026 [1]. The company said the price increases will reach a maximum of approximately 8% [1]. In addition to the price hikes, Lake will reduce the quantity of snacks in seven large-size product lines [1].
Lotte will implement price increases for 35 ice cream products starting in July 2026 [1]. These price hikes are more significant than those at Lake, with a maximum increase of approximately 16% [1].
Both companies said a combination of rising labor costs, logistics expenses, and raw material prices drove these changes [1]. A specific point of concern is the cost of naphtha, a petroleum derivative used in packaging and materials. Livedoor News said that trade restrictions via the Strait of Hormuz amid worsening Middle East conditions have kept naphtha prices high [2].
This trend is part of a wider surge in food and beverage price adjustments across Japan. According to Teikoku Databank, 1,078 food and beverage items were scheduled for price increases in June 2026 [3]. That number is expected to rise significantly, with 2,269 items scheduled for price hikes in July 2026 [4].
MSN Money said that chemical manufacturers have seen a succession of price hikes for materials derived from petroleum products due to the influence of the situation in Iran [5].
“Lake will increase prices for 12 potato chip products starting in August 2026.”
The simultaneous price hikes by Lake and Lotte underscore how geopolitical instability in the Middle East directly impacts the Japanese retail shelf. Because naphtha is a critical precursor for the plastics used in snack packaging, the volatility of oil prices is forcing companies to choose between shrinking product sizes—known as 'shrinkflation'—or raising prices to maintain margins against rising labor and logistics costs.
