Costco Kewpie Mayonnaise Review

Are you wondering what Japanese mayonnaise is and why it’s so amazing? If you are, you’ve come to the right place. Costco is carrying the Kewpie Mayonnaise that’s been increasing in popularity across North America but has been a staple in Japan since the 1920s. I hadn’t tried it until we picked up a bottle at Costco while on vacation. Today I’m sharing everything you need to know about this umami delight!

Other dips and sauces I like from Costco are the Kinder’s Chicken Dipping Sauce, Good Foods Chunky Guacamole, Rojo’s Street Corn Dip, Culinary Treasures Jalapeno Lime Aioli, Kewpie Deep Roasted Sesame Dressng & Marinade, Kirkland Signature Organic Marinara from Tuscany, La Terra Fina Queso Dip with Cheddar and the Good Foods Plant Based Queso Style Dip.

We found this in Kona, Hawaii in the aisle with all the other dips and sauces (non-refrigerated). The item number is 1710454.


How does Kewpie mayo compare to regular mayonnaise?

I really like this mayonnaise! It’s definitely different than regular mayonnaise. It’s more tangy and less sweet. With that being said, it’s not so different from regular mayonnaise that you can’t use it on all the things you’d use regular mayonnaise on.

Quite a bit more yellow in color than regular mayonnaise from the egg yolks used.

Because they use only egg yolks and there’s MSG in the mayonnaise it has a really strong umami flavor. The consistency of the mayo is also a bit thinner than traditional mayonnaise.

The price is reasonable, $5.99 USD for a 710-milliliter bottle of mayo. Yes, it’s a bit more expensive than your standard regular mayo, but it’s unique in flavor!

The Kewpie mayo cannot be frozen.


The bottle has a best-before date that’s about nine months from when we purchased it. Once opened it needs to be kept in the refrigerator. The mayo is a product of the USA with domestic and imported ingredients.

What to do with Kewpie Mayo?

You can use this mayonnaise on anything you’d use traditional mayonnaise on. It works with burgers, sandwiches, egg salad, potato salad, fish tacos or as dip for chicken or fries.

Some other ideas are to use it to make spicy tuna, add it to fried rice, use it to make homemade California rolls or use it as a dip for chicken kaarage.

The strong umami flavor of the mayo pairs well with the pork belly!



One tablespoon contains 100 calories, 12 grams of fat, 115 milligrams of sodium, zero grams of carbohydrates, zero grams of fiber, zero grams of sugar and zero grams of protein. That’s pretty high in calories and fat.

Nutrition facts.


The ingredient list lists a few unhealthy non-nutritious ingredients you typically see in mayonnaise. Oil, egg yolks and vinegar being the main ingredients.

Monosodium Glutamate, also known as MSG deserves mentioning because some individuals try to avoid it. Calcium Disodium EDTA is a preservative to keep food from spoiling and also preserves flavor.

The Kewpie Mayonnaise is gluten-free and dairy-free but does contain egg.

Give it a try!

For a unique, different-tasting mayo I highly recommend this. It’s just as versatile as regular mayonnaise, but I find it a little less sweet and tangier.

  1. I’ve been hearing about this mayo for quite awhile so will look for it at my big C. I don’t find regular mayo (Hellman’s) sweet at all. Are you possibly referring to Miracle Whip? Some people call that mayo, (imho it’s revolting😝) but I grew up thinking it was mayo until I had the real thing! Thanks for your review. 😁

  2. Wouldn’t you typically criticize soybean oil? Here it’s the first ingredient and you gave the nutrition a 10/10.
