Koikeya Strong is a potato chip brand loved especially by younger consumers, enjoyed as a reward during relaxation time or as the perfect snack with drinks. Each year, in January, timed with the plum blossom season, they release the popular “Koikeya Strong” plum flavor, celebrated for its bold winter-perfect taste that combines the sharp tang of plum with the savory richness of bonito flakes. This year, this beloved flavor has been taken to the next level with Ume Zanmai, a richer and more authentic taste experience. Building on the original flavor, it now features a luxurious blend of three ingredients: tangy red shiso to accentuate the sourness, refreshing green shiso, and rich plum pulp for a deeper, more indulgent plum flavor.
