Finally Instant Cup Noodles Made With Cold Water

Nissin Cold-Water Cup Noodles

Nissin Foods' new Cup Noodles variant is designed to be prepared with cold water, eliminating the need for hot water or a microwave. This product, announced in March 2025, belongs to the instant noodle category and solves the problem of inaccessible hot water sources, such as during travel, outdoor activities, or in emergency situations.

The product is manufactured by Nissin Foods Holdings Co., Ltd., the Japanese company that invented instant noodles. It is currently available only in Japan, with no announced international release date. The official product page is hosted on Nissin's Japanese website.

Key Facts

How Does the Cold-Water Cup Noodles Work?

The product uses a modified noodle structure and seasoning formulation that allows hydration and softening in cold water within 15 minutes. Unlike traditional instant noodles that require near-boiling water to gelatinize the starch, Nissin's cold-water version employs a different starch processing technique that enables rehydration at lower temperatures.

According to Kotaku's report, the noodles are pre-cooked and then dried using a method that leaves them more porous, allowing cold water to penetrate quickly. The seasoning powder is also reformulated to dissolve in cold water without clumping. A Nissin representative stated, "We wanted to make instant noodles accessible anywhere, even without hot water." The company tested the product for over two years to achieve the same texture and flavor as the hot-water version.

Nissin's cold-water Cup Noodles require exactly 15 minutes of soaking in cold water, compared to 3 minutes for the hot-water version.

Who Is This For?

This product is designed for consumers who lack access to hot water, including travelers, campers, office workers, and emergency preparedness kits. It also appeals to people in regions with unreliable electricity or gas supply, or those who prefer not to use a microwave or kettle.

Nissin's market research indicated that 34% of Japanese consumers have experienced a situation where they wanted instant noodles but had no hot water. The cold-water version targets this unmet need. It is not intended to replace the original hot-water Cup Noodles, but to complement it in specific use cases.

In a survey cited by Kotaku, 78% of testers rated the cold-water noodles as "acceptable" or "good" in texture and flavor.

How It Compares to Traditional Cup Noodles

The cold-water version costs 20 yen more and takes five times longer to prepare, but requires no heat source.

Common Questions

Can I use hot water with the cold-water Cup Noodles?

Yes, but it is not recommended. Using hot water will overcook the noodles and may cause the seasoning to become too salty. The product is optimized for cold water; hot water will produce a different texture and flavor.

Where can I buy the cold-water Cup Noodles outside Japan?

As of March 2025, the product is only sold in Japan through convenience stores and supermarkets. Nissin has not announced an international release. Importers may carry it, but availability is limited and prices will be higher.

How long does the cold-water Cup Noodles last after preparation?

Once prepared, the noodles should be consumed within 30 minutes for best texture. After that, the noodles continue to absorb water and become mushy. The product is not designed for long-term storage after rehydration.
