Holding the ¥100 line — no price rise, betting on the profits of the last one standing (2024)

Reading a constraint as a strategy

The ¥100 format rests on a constraint: the price cannot be moved. A weak yen and rising input costs attacked that constraint as a weakness. The core of president Kawai Eiji’s judgment was to take the weakness itself as the premise of the strategy. Retreat into a price rise and you lose the only sign you have. Hold the line and margins thin, but customers drift over from stores that raised prices in the same squeeze, and demand is left behind on the sites of competitors who could not endure and withdrew. The phrase “the profits of the last one standing” states that reversal in a few words.

Whether the bet pays turns on how long high input costs persist. If the rise becomes permanent, there is a limit to how much can be absorbed inside ¥100. Even so, Seria is trying to hold its ground on that single point — relying not on scale and not on a wider price range, but on its ability to keep swapping the assortment through data. A company that once chose to compete on the precision of information rather than on size has now chosen to keep changing the contents rather than the price. The same instinct for turning a constraint to advantage repeats itself a quarter of a century apart.
