I always order hijiki salad when I’m at an izakaya, about to toast the end of a workday. I love the classic Japanese combination of sweet and umami, and the tender carrots and seaweed. Making this traditional Japanese otsumami at home is very easy – it can be made with just 10 ingredients and be ready to serve in under an hour. 

Hijiki Seaweed Salad

What is Hijiki?

Hijiki (ヒジキ) is a brown seaweed that grows around the rugged coastlines of Japan, Korea, and China. The seaweed is high in calcium, iron, magnesium, and other essential minerals, and has been used in Japanese cooking for centuries.

The most common hijiki dish is hijiki no nimono – a combination of hijiki, soybeans, konjac, aburaage, and sliced carrot simmered in dashi, soy sauce, sake, mirin, and sugar. It’s served as a side dish or as otsumami, which are small dishes offered with beer and other alcoholic beverages, similar to Spanish tapas.

Where to Buy Hijiki

Hijiki is sold in dry form and can be found in Japanese and Korean supermarkets, and sometimes in Southeast Asian and Chinese grocery stores. It’s usually located in the seaweed aisle and comes in small bags. It can also be purchased online, such as here on Amazon.

Ingredients for Hijiki Salad (Hijiki No Nimono)

  • Hijiki seaweed: Hijiki is quite different than other seaweed in that the pieces are thin and short, almost like little worms. Hijiki itself isn’t very flavorful which is why it’s simmered in sauce or served in salads, to take on other flavors. The seaweed must be soaked and rehydrated before it can be used.
  • Oil: Any neutral oil such as vegetable or grapeseed works here. We only need a little bit to saute the carrots and other ingredients.
  • Carrot: The julienned carrot adds a little sweetness and a nice vibrant pop of color.
  • Aburaage: Both aburaage and inariage can be used. The difference between the two is that aburaage are plain deep fried tofu pouches, while inariage are deep fried tofu pouches that have been soaked in a mixture of soy sauce, mirin, and sugar.
  • Edamame beans: Since I didn’t have traditional soybeans to make this nimomo, I’ve used edamame beans which are just as good (and prettier too!).
  • Dashi: Dashi adds a briny element to this salad which pairs nicely with the mineral taste of seaweed.
  • Soy sauce: For a dash of umami and saltiness.
  • Sake: Sake adds a little fruitiness and sweetness.
  • Mirin: Mirin is similar to sake but sweeter.
  • Sugar: Plain white sugar or brown sugar can be used.

How to Make Hijiki Salad

  1. Gather all of your kitchen tools and ingredients.

Hijiki and Arsenic – How Much is it Safe to Consume?

While hijiki has been consumed for centuries in Japan and is considered a healthy food, the US, Canada, and UK food safety agencies are on the fence about its consumption due to the fact that it contains traces of inorganic arsenic.

Inorganic arsenic is considered a carcinogenic and consuming too much can lead to gastrointestinal issues such as diarrhea and abdominal pain, as well as liver damage.

However, the Japanese Ministry of Health and Labor has said that consumption under 4.7g per day, which is well above what Japanese people consume, is completely safe (the average consumption being around 0.9g per day in Japan).

What this basically means is that eaten in moderation, hijiki seaweed is safe since the arsenic levels consumed are too minor to have harmful effects.

What to Serve with Hijiki Salad

Since hijiki salad comes in very small serving sizes (otsumami size), it goes without saying that you can’t make a meal out of it. However, it makes a wonderful addition to bento boxes and traditional Japanese dinners. Here are some of my favorite Japanese dishes that I like to pair with this salad:

How to Store Hijiki Salad

Store hijiki salad in a storage container or bowl covered with plastic wrap and refrigerate for up to 3-4 days. You can also freeze hijiki salad but make sure to drain as much of the liquid as you can to prevent the ingredients from getting soggy and mushy.

To thaw, leave the salad in the fridge overnight before eating or reheating, if you prefer it warm.
