From wheat to potato: building the supply chain (1973)

A raw-material switch that became vertical integration

The decision that defined Calbee was not a new product but a change of raw material. In 1973 it dropped “Confectionery” from its name and, over the following years, moved its mainstay from wheat sweets to potato snacks, launching Potato Chips in September 1975. Unlike wheat, which could be imported, potatoes had to be procured almost entirely at home, on a harvest calendar the company did not control. That single fact turned a confectioner into something closer to a processing industry: to guarantee the quality and volume of a perishable crop, Calbee could not simply buy on the open market. In 1980 it set up Calbee Potato in Hokkaido to contract directly with farmers and breed its own seed potatoes — internalising the one input a snack maker would normally leave to a supplier.

What looks like a menu change was in fact a bet on owning the chain. Around the fresh-potato supply Calbee arrayed factories close to the growing and consuming regions, and later its own logistics, so that procurement, production and distribution all answered to one company. That capital-intensive structure is what let a single category harden into a near-monopoly — Potato Chips and, from 1995, Jagariko — and it is the same structure that tied Calbee’s fortunes to the Japanese potato harvest. The strength and the vulnerability are one and the same: the more completely it owned the crop, the more a bad year in Hokkaido could reach straight into its earnings. Everything the later Calbee became — dominant at home, hard to dislodge, and exposed to a single field — was set in motion by the choice to build the potato supply itself rather than buy it.
