Why Higher Rice Prices Do Not Translate Directly into Higher Sake Prices

When the price a brewery pays for rice rises, its costs increase. But can raising product prices alone make up for that increase? Order volumes may fall after a price change, leaving breweries to contend with both ingredient costs and sales.

Research on Japanese sake breweries by Jun Sato of the University of Niigata Prefecture reveals the difficulties that lie between rising ingredient costs and the price of the finished sake.

Separating Rice Costs from the Overall Cost of Brewing

The research was based on a survey conducted in November 2025. A total of 115 companies across Japan responded. Among the 113 whose responses on rice purchase prices could be quantified, the average increase in 2025 compared with 2023 was 95.3%, close to double the earlier level. This is an estimate derived by quantifying the responses, and the sample is skewed toward small and medium-sized breweries. It should be distinguished from nationwide rice market prices or an average representing all sake breweries.

The rice discussed here is rice used in sake brewing. Sake requires rice for making rice koji, as well as other rice added to the mash. Because rice is an essential ingredient, changes in its unit purchase price affect a brewery’s costs.

Brewing also involves costs beyond rice, including bottles, boxes, electricity and labor. Even if rice costs nearly double, total production costs do not necessarily increase by the same proportion. The scale of the impact depends on how much of the original cost was accounted for by rice.

The rice-price increase alone cannot be used to set the same percentage product-price adjustment for every sake.

Raising Prices and Maintaining Profits Are Separate Questions

Reflecting increased costs in product prices is known as “cost pass-through.” In the study, 72 companies could be assessed using their actual price increases in 2025 and planned increases for 2026. Assuming sales volumes remained unchanged, 22 had a cumulative increase for 2025 and 2026 that fell short of the adjustment calculated to cover the rise in rice costs alone. The figure of roughly 30% uses these 72 companies as its denominator. Because plans are included, these are not all results of changes already implemented.

Would a price increase large enough to cover higher rice costs secure a brewery’s finances? Even if revenue per bottle increases, total sales revenue may not rise as hoped if fewer bottles are ordered. Furthermore, reducing production does not necessarily allow the costs of maintaining equipment and employing staff to fall by the same proportion.

The study models this relationship using estimates from earlier research, based on retail purchase data, of how sales volumes respond to price changes. The volume declines presented are not outcomes observed across all sake breweries. They illustrate the difficulties that arise when calculations are made under certain assumptions.

Adding higher ingredient costs to the price and keeping a brewery financially able to continue production are separate challenges. Between them lies another issue: changes in the quantity sold.

Where Does the Burden of Ingredient Costs Fall?

This survey alone cannot explain why a particular sake’s price was revised, or determine its selling price in Thailand. Between leaving a Japanese brewery and arriving across borders, factors such as transport and exchange rates come into play alongside the cost of rice. The Japanese survey results and the price of a bottle seen in Bangkok are connected, but they are not the same figures.

A change in price should also be distinguished from a change in ingredients or production methods. The cost of continuing with the same methods may increase, or the product itself may be reconsidered. For individual products, the starting point is to understand the producer’s explanation.

For those securing rice supplies, the unit price is not the only consideration. When the rice will be needed, and how much, also matter. How far can farmers, distributors and breweries share their expectations for the future? Will breweries bear the increased costs alone, or will the burden be shared further along the supply chain? These questions extend beyond the brewing process itself.

To understand sake price increases, it helps to follow rice costs, product prices and sales volumes in turn. Behind the simple statement that ingredients have become more expensive, what are producers working to continue, and what burdens are they taking on to do so? The research reveals the difficulty of sustaining sake production, a challenge that revising prices alone cannot resolve.
