Summer cookouts and holiday get-togethers are where potato salads typically shine, but this recipe for Japanese Potato Salad (ポテトサラダ) is one that I enjoy making year-round. In Japan, it shows up in bento boxes, convenience stores, and even as a bar snack at izakaya

Today, let‘s learn how to make this classic Japanese potato salad that all ages will love.

What is Japanese Potato Salad?

Much like potato salads in the US, Japanese potato salad is a popular party dish and it’s been a popular dish in Japan for over 120 years. It has the perfect balance of rich, tart flavors with a touch of sweetness and a pleasant variety of textures. 

As with many other yoshoku dishes (like Curry Rice, Croquettes, and Tonkatsu), potato salad likely made its first appearance during the Meiji Era (1868-1912). After a Japanese chef tried to recreate the popular Eastern European Olivier Salad (also known as Russian Salad), this Japanese version quickly gained popularity. 

What Makes It Different from Other Potato Salads?

German and American potato salads are often strong vinegar-based with chunks of waxy potatoes and ingredients like mustard, bacon, and fresh parsley or chives. But in the Japanese version, you will find a variety of colorful ingredients like carrots, corn, hard-boiled eggs, cucumber, and ham.

The vegetables add sweetness and substance to the salad, and the simplicity of seasonings delivers a balanced flavor.

Every family in Japan has their own take on potato salad, and that’s one of the many things I love about it. You can add ingredients of your choice (e.g., onion, peas, string beans, apple, or canned tuna). It will be just as nutritious and eye-catching.

The potatoes are almost completely mashed (but I recommend leaving a few chunks), so the texture is creamy. Most importantly, the key difference in flavor comes from the type of mayonnaise we use (more on this below).

Ingredients for Japanese Potato Salad

You can find most of the ingredients for this potato salad in a regular supermarket. See the recipe card below for the full ingredient list.

Jump to Recipe
  • Russet Potatoes – Waxy potatoes are commonly suggested for potato salad, but there is a reason we use a starchier potato for this recipe. Japanese potato salad is creamier in texture than its Western counterpart. While we don’t mash them all the way, the texture of russet potatoes makes it easy to break up while mixing. 
  • Corn – I love the addition of corn to the potato salad. The tiny kernels are packed with sweetness and embody the flavors of summertime. You can use canned or frozen for easy preparation. 
  • Carrots – This adds another element of natural sweetness to the salad.
  • Cucumber – Mixing thinly sliced cucumber into the salad gives it a refreshing flavor, not to mention a nice crunch!
  • Boiled egg – Egg and potatoes are extremely complementary. Plus, the added protein makes it a substantial dish. 
  • Ham – If you don’t eat meat, simply omit it! 
  • Seasonings Kewpie Japanese mayo, rice vinegar, salt, and freshly ground black pepper.

What is Kewpie Mayo?

KEWPIE (キューピー) is the most popular brand of Japanese mayonnaise. To make the potato salad distinctly Japanese, you must use Japanese mayonnaise, which adds a rich and tangy component that you can’t easily substitute.

You can find the famous, red-capped squeeze bottle of Kewpie mayo in most Asian grocery stores or on Amazon. Some mainstream grocery stores such as WholeFoods and Target may also carry Keypie mayo now. Make sure you get the imported, Japanese package Kewpie because American packaged one tastes differently from the imported version.

How to Make the Best Japanese Potato Salad

Here is a quick overview to make Japanese potato salad.

  1. Peel, cut, and boil the potatoes until a skewer pierces a potato smoothly, about 15 minutes.
  2. While cooking the potatoes, prepare the rest of the ingredients.
  3. Once the potatoes are done, mash the cooked potatoes and season them. Let cool completely.
  4. When the potatoes are cool, combine them with the other ingredients.
  5. Season the potato salad with Japanese kewpie mayo. Chill and serve!

Cooking Tips

It’s a very easy recipe, but to make the best Japanese potatoes, don’t forget to follow these tips!

  1. Cut ingredients into a bite-sized, uniform shape – Because of the smooth texture of the smashed potatoes, you‘ll want to cut the other ingredients into small pieces so they incorporate well.
  2. Remove excess moisture from all ingredients – Excess moisture will ruin the texture and flavors of potato salad. So it‘s key to withdraw the moisture from cucumbers and potatoes before mixing them all.
  3. Add seasonings to hot potatoes – The potatoes will absorb flavors well when they are still warm. So add rice vinegar and pepper, except for the mayonnaise! Read next.
  4. Let the potatoes cool – Hold on to the mayo. If you mix mayonnaise while the potatoes are hot, the mayonnaise will separate. Therefore, work on the other ingredients while the potatoes cool down. It‘s a good idea to start cooking the potatoes first to give them plenty of cooling time.
  5. Gradually add mayonnaise – We all want to use less mayonnaise, but it is the main flavor so you just can‘t skimp here. I suggest adding just two-thirds of the mayo first, then taste to see if you want to add the rest. A sprinkle of salt can bring out the flavors you need.
  6. Chill the potato salad before serving – Not only does it taste better, but chilling also gives time for the flavors to meld together.

How to Store Japanese Potato Salad

You can keep the leftovers in an airtight container and store in the refrigerator for up to 3-4 days or in the freezer for 2-3 months.

What to Serve with Japanese Potato Salad

You can‘t beat the versatility of this salad! For that reason, it’s a dish that you can pair with just about anything. Some other ways I like to enjoy Japanese Potato Salad are alongside Karaage (fried chicken) or Hambagu (Japanese hamburger steak).

If you’re having a barbecue or attending a potluck, see my list of Japanese recipes that go perfectly with this potato salad. 

We rarely have leftovers of this dish in my house, but when we do, I love making these Potato Salad Pork Rolls.

Prep Time: 20 minutes
Cook Time: 30 minutes

Ingredients
 
 

  • 2 russet potatoes (1.15 lb)
  • 2 tsp Diamond Crystal kosher salt (for cooking the potatoes)
  • 2 inches carrot (2 oz, 60 g)
  • ¼ cup frozen or canned corn (I used frozen corn, cooked for 5 minutes)
  • 1 large egg (50 g each w/o shell)

    Japanese Potato Salad Ingredients

To Prepare the Potatoes

  • Peel 2 russet potatoes and cut them into 1½-inch (3.8-cm) pieces; I usually cut one russet potato into four pieces. They should be roughly the same size so that they’ll cook evenly.
    Japanese Potato Salad 1
  • Put the potatoes in a medium pot and add cold water to cover by 1 inch (2.5 cm). Add 2 tsp Diamond Crystal kosher salt to the pot and turn on the heat to medium high. Cover with the lid, leaving it slightly ajar to avoid a boil-over. Tip: Start cooking the potatoes in cold water to heat them up slowly so they cook through evenly. While you‘re cooking and cooling the potatoes, prepare the other ingredients (see next section).
    Japanese Potato Salad 2
  • Once the water is boiling, remove the lid and reduce the heat to medium. Cook on a gentle boil until a skewer pierces a potato smoothly, about 15 minutes.
    Japanese Potato Salad 13
  • Drain the water completely from the pot using the lid to hold back the potatoes. Put the pot with the potatoes back onto the stove over medium heat to evaporate any remaining water completely, shaking the pot constantly to avoid sticking. When there is no liquid left, remove the pot from the heat.
    Japanese Potato Salad 14
  • Mash the potatoes lightly, leaving some small chunks for texture. Transfer the potatoes to a large bowl.
    Japanese Potato Salad 15
  • While the potatoes are hot, add 1 Tbsp rice vinegar (unseasoned) and freshly ground black pepper. Set aside to cool. Why not add mayonnaise here? If you add it while the potatoes are hot, the mayonnaise will separate. Therefore, work on the other ingredients while the potatoes cool down.
    Japanese Potato Salad 16

To Prepare the Other Ingredients

  • While the potatoes are cooking and cooling, prepare the other ingredients. Bring a small pot of water to a boil for cooking the carrots and corn (next step). Peel and cut 2 inches carrot in half or quarters lengthwise, and then cut crosswise into thin slices. You may use a mandoline slicer to cut it thinly.
    Japanese Potato Salad Update 1
  • Once the water is boiling, cook the carrot slices and ¼ cup (40 g) frozen corn for 5 minutes. If you‘re using canned corn, you don‘t need to boil it.
    Japanese Potato Salad Update 2
  • Alternatively, you can use the microwave to heat the carrot for a few minutes until a skewer pierces it smoothly; don’t overcook them or they will get mushy. Drain the water in a fine-mesh sieve and set aside to cool.
    Japanese Potato Salad Update 3
  • Add 1 large egg (50 g each w/o shell) to the same pot and add enough cold tap water to cover by 1 inch. Turn on the heat to medium and bring to a boil. Once boiling, set a timer for 11–12 minutes and reduce the heat to maintain a gentle simmer. When the timer goes off, shock the egg in cold water until cool.
    Japanese Potato Salad Update 8
  • Remove and discard the shell. Slice the boiled egg and chop it into smaller pieces. Set aside.
    Japanese Potato Salad Update 4
  • Peel 1 Persian cucumber (leave some skin on to create a striped pattern), and thinly slice it. Tip: If you‘re using a large cucumber, you may need to cut it in half or quarters lengthwise before slicing it.
    Japanese Potato Salad 3
  • Sprinkle ½ tsp Diamond Crystal kosher salt over the cucumber slices, knead them with your hands, and let them stand until they release their moisture, about 5 minutes. Then, squeeze the cucumber to remove any moisture and set aside. Tip: Salt draws out moisture from the vegetables through osmosis. This process keeps them from releasing moisture into the salad and diluting the flavors.
    Japanese Potato Salad Update 6
  • Cut 2 slices Black Forest ham into 1-inch (2.5-cm) thin strips and set aside.
    Japanese Potato Salad 12

To Assemble

  • Add all the ingredients to the bowl of the cooled potatoes and mix all together.
    Japanese Potato Salad Update 7
  • Add 4 Tbsp Japanese Kewpie mayonnaise and combine well.
    Japanese Potato Salad 20
  • Taste to see if you want to add more mayonnaise. I added the remaining 2 Tbsp Japanese mayonnaise. You can also add salt to bring out the flavor instead of adding more mayonnaise. You can serve the potato salad immediately, but I recommend refrigerating it for 30–60 minutes before serving.
    Japanese Potato Salad 21

To Serve

To Store

  • You can keep the leftovers in an airtight container and store in the refrigerator for up to 3–4 days or in the freezer for 2–3 months.

I may make the salad today. I recently received my Kewpie mayo from Amazon. I ordered it especially to make this salad. Looking forward to enjoying it. Thank you.

Hi Barbara!
We hope you enjoyed this Japanese salad.
Here is the link for Nami’s recipes with Japanese Mayo. Please check it out!: https://www.justonecookbook.com/#search/q=mayo

I think every nihonjin no matter the country has their own way of making this. Here in Shizuoka not one of my family or friends makes it the same. Btw I use kani potato salad is very versatile there is no right or wrong way pardon my english (^ _ ^ )

Hi Sachiko!
Yes. We agree with you. Each family and region has a different way to prepare Japanese dishes, and they are all delicious!
Thank you for your input.☺️

This is about the 4th time using your potato salad recipe. It just occurred to me…in your recipe you do not salt and drain the liquid from the cucumber slices? In the past, I’ve done this automatically on my own.5 stars

Do you ever put wasabi in your potato salad? I’m sure that my mother’s potato salad had a spicy component, but by the time I asked her, she didn’t remember.

Hi! I’ve been making a similar version of Japanese potato salad (my Mom’s recipe) for years. I started using the instant pot to cook the potatoes & carrots and also to boil the eggs, and it makes things SO much easier. I just put the potato and carrot chunks in a steamer basket, add 1c water, and cook at high pressure for 5 minutes, then let the pressure drop naturally. I boil the eggs by placing cold eggs point down on an egg trivet, add 1c water, and cook for high pressure for 5 minutes. I then let the pressure release for 5 minutes, then place in an ice bath for 5 minutes. Works perfectly every time, so I thought I would share <35 stars

This is so good! I made a double batch since I plan on having it as a side throughout the week (though I don’t know if it will last that long since everyone loves it!) I made some homemade Japanese pickled cucumbers and used those as well as some of the pickling liquid. Definitely enhances the already delicious flavor of the potatoes! Will definitely make this again!!

I’ve always enjoyed this dish at a local Japanese restaurant I go to, and I just made this last night. It was delicious, I want to make it again very soon. It had just the right amount of creaminess, saltiness, tang, crunch, so tasty!

I love Japanese “mashed” potato salad! Found this recipe and it seemed easy enough. I didn’t have enough Kewpie mayo so I followed the recipe using American mayo. The salad came out great! I’ve been having a hard time finding it at restaurants so now I can make my own 😊5 stars

I love your recipes! They’re easy and taste like what I would get at the store or restaurant. I tried your dorayaki recipe a few weeks ago and that also came out great. Will definitely try more of your recipes. Thanks Nami!

So fresh and full of colour! It’s nice to have a chilled side dish for dinner sometimes and this was a perfect choice. Had to replace cucumber with red capsicum since I was too lazy to go to the shops haha. I’m looking forward to making it into your potato salad pork rolls!

As always, thanks Nami!5 stars

This recipe was delicious & simple to make. While it was tasty when made, it was even better the next day. I really enjoyed the textures & colours of the cucumber, carrots & corn in contrast to the mashed potatoes. The flavours were excellent. This is a recipe that I will certainly make again. Thank you!5 stars

Made this today for lunch to go with homemade Aussie meat pie. Was delicious, love the crunch factor

After visiting Japan I was inspired to try to recreate some of my favourite Japanese dishes and more. This potato salad was a crowd favourite, so flavourful and a perfect side dish! Followed the recipe exactly, except I boiled potatoes straight with boiling water because I was in a rush.
I wish I found this website sooner and am excited to try your other dishes!

Greetings Nami,

Can do following substitute if I don’t have some ingredients as per your recipe:
Ham substitute with crabstic
Cucumber replacing with apple
Omitting corn if have non

Thanks for your kind guide 😘😘5 stars

I made this once before following your recipe….to take to a potluck luncheon at my Quaker Meeting. People really enjoyed it–called it “Japanese Mashed Potato Salad”. I made it again, for our supper and I am going to serve it with those panko breaded ham slices that you posted yesterday and a green salad on the side.

Last night I made the creamy mushroom spaghetti….using enoki, crimini, and shiitake mushrooms…and not forgetting to add the soy sauce….What a splendid dish that was. I told my husband Masahiro I got the recipes from you Nami….arrigato….but that his mother had her skilled eye on me all the way from her hospital bed in Kitakyushu.

We love Japanese potato salad! Thank you for the wonderful recipe! My mother-in-law adds bits of Fuji apple to her potato salad. It’s a delicious addition.5 stars
