However, I should warn you that storing Sushi requires a fair amount of preparation.

How Long Does Sushi Lasts in the Refrigerator

Generally, the time that sushi lasts in the refrigerator is dependent on the ingredients used, and on the temperature. Some spoil faster, others more slowly.

So as a rule of thumb for maximum freshness and quality sushi is best enjoyed within 24 hours from when it is made to being placed in the refrigerator.

How to Store Leftover Store Bought Sushi

Once you have opened the packaged store bought sushi, you must repack the sushi by wrapping every individual sushi in plastic wrap tightly together before placing it into an airtight container in the refrigerator. Check the sell-by date and Don’t eat sushi after that point in time. Period!

Most prepackaged grocery store sushi has a 2-3 day shelf life. This is because the rice for these rolls are over-saturated with sushi rice dressing to compensate for the drying out of the rice. Also, extra preservatives and corn syrup are often also added to the rice.


If you are buying store-bought packaged sushi it is required by the FDA to be refrigerated. If it’s not in the refrigerated section of your supermarket, don’t buy it.

While some people might want to store their sushi for a period longer than 24 hours in the refrigerator, we don’t advise that since the quality of sushi deteriorates after this period since:

  • The rice in the sushi begins to dry out in the refrigerator making it stiff and hard after just a few hours.
  • Traditional Sushi with raw fish is usually only good for 24 hours in the refrigerator too because the raw fish mixes with other ingredients in the sushi making it soggy as well as more susceptible to spoilage.  
  • Nori usually found in some sushi becomes tough and chewy in the refrigerator

If the seafood is cooked, it can be eaten for a day or two beyond the 24 hours, but the quality decreases quickly with each day mostly due to the rice losing moisture and becoming hard.

If your sushi is left for period longer than 4 hours bacteria will begin to form on the rice. If rice is left at room temperature for eight hours or more a bacteria called Bacillus cereus will grow in it, which can make you sick.
