Japanese Potato Salad

If you love creamy and eggy salad, you are going to love this Japanese potato salad. This salad is loved by young and old, and if you have ever visited Japan or any Japanese restaurants really, I am sure you will have tried this by now. For those of you who like preparing bento box, this is a pretty common side dish to prepare :)

Ingredients for a basic Japanese potato salad: potatoes, hard-boiled eggs, cucumber, carrot, onion, Japanese mayo (e.g. Kewpie), salt, and pepper.

What goes into a typical Japanese potato salad?

The most basic of Japanese potato salad will have these ingredients:

  • boiled and lightly mashed potatoes, preferably waxy potatoes such as Yukon, red, new, or fingerling
  • hard-boiled egg
  • carrot
  • thinly sliced cucumber
  • thinly sliced onion
  • Japanese mayo, such as Kewpie
  • salt and pepper

Other add-ons that will work beautifully include:

  • diced apple, my favorite is Fuji apples
  • diced Asian pear
  • raisins or dried cranberries

If you are making this potato salad for non vegetarians, I highly recommend adding some of these:

  • diced ham
  • crumbled crispy bacon

Homemade Japanese mayonnaise

You only need mayonnaise, salt, and pepper for the dressing. It is best if you can find Japanese Kewpie mayonnaise as it is quite different in taste compared to regular mayonnaise. But for short cut, you can use this formula from Just One Cookbook to make your own Japanese style mayonnaise

1 cup regular American mayonnaise + 2 tablespoon rice vinegar + 1 tablespoon sugar

    Ohhh...I remember having this Japanese Potato salad long time ago and I loved it ever since!!! This looks amazing!

    • Anita Anita says:

      Thanks Marv! If it has been a long time, you should give this a try :)

  • jean jean says:

    Love a good potato salad and this Japanese version sounds delectable!

    • Anita Anita says:

      I know right? Every time presented with a choice of salad, I end up going with potato ones, haha. I really must try to be more adventurous.

  • Sasha Gill Sasha Gill says:

    I have never tried the Jap version of a potato salad but I must say, sounds delicious! I also remember preferring jap mayo to the western ones... it's a little sweeter and more subtle. So I can imagine this potato salad is even better than western ones!

    • Anita Anita says:

      Yeah, there's just something more in Japanese mayo. It is more expensive compared to regular mayo, but totally worth it.

  • JinJoo Lee JinJoo Lee says:

    Koreans have a very similar potato salad version that I think originated from Japan. Apples are a must and we sometimes even add cabbage. Looks so yummy and beautiful! thank you!

    • Anita Anita says:

      Yes, apples in potato salad are such a good match it's kinda sad when I don't have apples at home whenever I make this salad :)

  • Healthy World Cuisine Healthy World Cuisine says:

    Kewpie Mayo is the best. Love this recipe as it reminds of us of living back in Yokohama. A classic recipe.

    • Anita Anita says:

      Yes indeed they are the best. I much prefer using Kewpie mayo to regular mayo even in recipes not specifically asking for it.

  • Tina Dawson | Love is in my Tummy Tina Dawson | Love is in my Tummy says:

    That is delicious! I have to keep an eye out for Kewpie mayo!!! Wonder what makes it taste different... hmm...

    • Anita Anita says:

      Personally, I think it's the use of rice vinegar, more sugar, and I am pretty sure karashi (Japanese mustard) and dashi is involved somewhere :)

  • Amy Amy says:

    I love a good potato salad. My mom is a huge potato salad fan. I can't wait to try this Japanese version and make it for her. Looks delicious!

    • Anita Anita says:

  • Shihoko Ura Shihoko Ura says:

    Japanese potato salad is staple home cooking dish in Japan. I often add sliced apple or raisin too.

    • Anita Anita says:

      Yes, I add apples and raisins too when I have them at home. They do make the potato salad so much more delicious from the added sweetness.

  • Char Ferrara Char Ferrara says:

    Oh my goodness, I am so excited to try this Japanese Potato Salad! Every time I find this in my bento box, it makes me so happy :D

    • Anita Anita says:

      Haha, I too like it when I find potato salad in my bento box. It's pretty weird how something simple to make at home makes us feel like that :)
