Our favorite potato sticks are now potato chips! Koikeya's Suppa Mucho Chips are bursting with flavor. Like an ode to the Japanese plum (ume) tree, every bite carries the floral notes of plum blossoms, the sourness of umeboshi (pickled plum), and the earthiness of shiso (perilla leaves). Hands down, this Japan-exclusive snack is the most addicting potato chip we’ve ever tried.
