Nissin Foods launches cold-water instant noodles

Nissin Foods has launched “Hiyashi Cup Noodle,” a new line of instant noodles designed to be prepared using only cold water. Developed over five years using a patented “Cold Rehydrate Method,” the product allows consumers to prepare the noodles in just five minutes without the need for hot water.

The initial release features two flavors: “Spicy Kimchi” and “Chicken Salt Lemon.” Due to high demand, the product reportedly sold out within one week of its July 20, 2026, release, significantly faster than the company’s initial sales projections.

The innovation has drawn international attention, particularly in South Korea, as the product's ability to achieve a proper texture using cold water marks a departure from traditional instant noodle preparation methods.
