Hijiki Rice is a colorful Japanese mixed rice (takikomi gohan) cooked in seasoned dashi with seaweed, carrots, and aburaage fried tofu. An integral ingredient in the Japanese diet for centuries, hijiki is a savory sea vegetable rich in minerals and dietary fiber. Enjoy this classic recipe, which is also vegan-friendly.

From a young age, I always loved classic Japanese ichiju sansai style meals with grilled fish, small sides, and rice and miso soup, while my friends were more interested in Western food and yoshoku (western-influenced Japanese food). I especially loved all kinds of Japanese mixed rice called takikomi gohan, and this Hijiki Rice was one of my favorites.

What is Takikomi Gohan?

Japanese Mixed Rice or what we call Takikoki Gohan (炊き込みご飯), is a Japanese dish made with short-grain rice and other ingredients. While regular rice is cooked with water, for mixed rice, we use dashi (Japanese soup stock) for more flavor.

Every season, we enjoy rice cooked with fresh seasonal ingredients, such as green peas or bamboo shoots in spring, corn in summer, sweet potato or chestnut in fall, and oyster or root vegetables in winter.

We would also serve mixed rice instead of plain white rice to complement a simple main dish for a colorful and appetizing meal.

What is Hijiki?

Hijiki (ひじき) is an edible dried seaweed renowned for its distinctive black, shredded appearance. Harvested along the rocky coastlines of Japan, Korea, and China, it starts as a vibrant green to brown hue when gathered, later transforming into a deep black after boiling and drying.

Hijiki Seaweed

Unlike the other seaweeds like wakame and nori, hijiki has a savory and earthy flavor profile, with a subtle brininess that allows its unique taste to shine through. It offers a pleasant crunch and a chewy bite upon cooking.

This traditional food has been a part of a balanced diet in Japan for centuries, valued for its taste and nutritional richness. Packed with dietary fiber, vitamins, calcium, and essential minerals, hijiki is eaten in Japanese, Chinese, and Korean cuisine. Have you tried it before?

Where To Buy Hijiki

There are two types of hijiki seaweed: small, soft “bud” parts called mehijiki (芽ひじき), which I used in this recipe, and long, chewy “stem” parts called nagahijiki (長ひじき), which are not commonly found here in the U.S.

You can find hijiki in the dried foods aisle of Japanese, Asian, and Korean supermarkets, as well as in natural food stores. You can also buy it on Amazon.

If you’re concerned about the warning label on these products, just know that unless you consume an entire package in one day, there’s no need to worry. Typical consumption is unlikely to affect your health.

How to Use Hijiki in Cooking

Before using hijiki, soak it in cold water for 30 minutes. Drain well, rinse under running water, and it’s ready for use. You can make various hijiki recipes!

Ingredients for Hijiki Rice

  • Japanese short-grain rice
  • Hijiki seaweed
  • Aburaage (fried tofu pouch)
  • Carrot
  • Seasonings: Vegan dashi, soy sauce (or tamari), mirin, and salt

This classic recipe is vegan-friendly with only plant-based ingredients. Typically, meat is not included, but you can do so by adding small pieces of chicken thighs.

How to Make the Best Hijiki Rice (Hijiki Gohan)

  1. Make vegan dashi by hydrating kombu and dried shiitake mushrooms.
  2. Soak hijiki seaweed and cut all the ingredients into small pieces.
  3. Rinse rice, and transfer to a rice cooker bowl (donabe, pot, or Instant Pot).
  4. Add the vegan dashi, seasonings, and ingredients, and start cooking.
  5. Let it steam after cooking, fluff the rice, and serve.

Cooking Tips

  • Take note of the rice cooker cup – If you’ve never owned a rice cooker, you might not be familiar with the rice cooker cup measurement. 1 rice cooker cup is 180 ml, equivalent to 3/4 US cup. This measurement is standard for all brands of rice cookers. If your rice cooker comes with a clear rice cooker cup, it typically holds 180 ml.
  • The ratio for Japanese short-grain rice to water is 1:1.1 or 1:1.2 – For 1 rice cooker cup (180 ml) of Japanese rice, you will need 200 ml of dashi, with seasonings factored into this calculation.
  • Do not mix rice and ingredients – This applies to all mixed rice recipes. You first need to mix the rice, dashi, and seasonings, but add other ingredients such as veggies on top without blending them into the rice. This ensures the rice is cooked evenly. Once the rice is done cooking, you can then mix everything together.
  • Always soak Japanese short-grain rice – The short-grain rice is more plump (thicker) than other varieties, so it requires a head start to absorb moisture to the core. Soaking for 20-30 minutes is standard.
  • Repurpose leftover hijiki rice into onigiri (rice balls) – Shape the leftovers into rice balls and pack them in your bento lunch box. They were my favorite type of onigiri growing up!

How to Store

  • To Refrigerate: I don’t recommend refrigerating cooked rice, even if you plan to eat it the next day, as the rice tends to become hard in cold temperatures.
  • To Freeze: Store Hijiki Rice in an airtight container and freeze it for up to a month.
  • To Reheat. For the best results, reheat in the microwave directly from frozen.

Hijiki Rice is a colorful Japanese mixed rice (takikomi gohan) cooked in seasoned dashi with seaweed, carrots, and aburaage fried tofu. An integral ingredient in the Japanese diet for centuries, hijiki is a savory sea vegetable rich in minerals and dietary fiber. Enjoy this classic recipe, which is also vegan-friendly.
Cook Time: 1 hour
Total Time: 1 hour
Servings: 4

Ingredients
 
 

  • cups uncooked Japanese short-grain white rice (1½ cups of uncooked rice are 2 rice cooker cups (10.6 oz, 300 g) and yield roughly 4 servings (3½ cups, 660 g) of cooked rice)
  • 3 Tbsp dried hijiki seaweed (I used mehijiki (芽ひじき), the small, soft “buds“ of the hijiki plant; you can also use the long and chewy “stems” called nagahijiki (長ひじき), which are less commonly found in the US)
  • 1 piece aburaage (deep-fried tofu pouch) (¾ oz, 20 g)
  • carrot (2.5 oz, 70 g)

For the Dashi (vegan-friendly)

For the Seasonings

Japanese Ingredient Substitution: If you want substitutes for Japanese condiments and ingredients, click here.

Instructions
 

  • Gather all the ingredients. Please note that this dashi requires a minimum steeping time of 30 minutes. Ideally, we let the dashi steep for 2–3 hours in the summertime and 4–5 hours in the wintertime.
    Hijiki Takikomi Gohan Ingredients

To Make the Dashi

  • Put 1 piece kombu (dried kelp), 2 pieces dried shiitake mushrooms, and 1⅓ cups water in a measuring cup. Let it steep on the counter for at least 30 minutes to extract the kombu’s flavor naturally. Tip: Most Japanese recipes recommend gently cleaning the kombu with a damp cloth. However, the kombu is pretty clean these days. Just make sure to dust off and remove mold spots, if any. Do not wash or wipe off the white powdery substance, as it has lots of umami. For the dried shiitake mushrooms, check if there is any dust or dirt trapped in the gills under the caps. If there is, use a pastry brush to clean it off. Do not wash it under water.

  • After steeping, it‘s now ready to use as cold brew Vegan Dashi.
    Hijiki Rice 5
  • Remove the hydrated kombu and shiitake from the measuring cup. See my suggestions at the end of the recipe for how to repurpose the spent kombu and shiitake. Then, add enough water to make 1⅓ cups (320 ml) dashi. Tip: The Japanese short-grain rice-to-water ratio is 1 to 1.1 (or 1.2). In this recipe, the dashi and seasonings together are considered the “water“ unit.

To Rehydrate the Hijiki Seaweed

  • Rehydrate 3 Tbsp dried hijiki seaweed in plenty of water to cover for 10 minutes. If you use nagahijiki, rehydrate for 20–30 minutes.
    Hijiki Rice 4
  • After 10 minutes, drain in a fine-mesh strainer and rinse under running water. Set aside.
    Hijiki Rice 9

To Wash the Rice

  • Put 1½ cups uncooked Japanese short-grain white rice in a large bowl and add just enough cold tap water to submerge the grains. Discard the water immediately (so the rice doesn‘t absorb the cloudy water). Next, use your fingers to gently wash the wet grains in a circular motion for 15–20 seconds. Add water to rinse and immediately pour off the cloudy water. Repeat this “wash and rinse“ process a couple more times until the water is clear. Drain the rice in a fine-mesh sieve and shake off the excess water. Set aside while you prepare the other ingredients.
    Rice Rinsing

To Cut the Ingredients

  • Cut 1 piece aburaage (deep-fried tofu pouch) in half lengthwise, then slice crosswise into thin strips (¼ inch, 6 mm).
    Hijiki Rice 2
  • Cut ⅓ carrot into thin slabs (⅛ inch, 3 mm) lengthwise. Then, cut the slabs into thin julienned strips; if they are too long, cut the strips in half.
    Hijiki Rice 3

To Cook the Rice

  • To your rice cooker pot (or donabe or heavy-bottomed pot), add the well-drained rice, 2 Tbsp usukuchi (light-colored) soy sauce, 2 Tbsp mirin, 1 Tbsp sake, and ½ tsp Diamond Crystal kosher salt.
    Hijiki Rice 7
  • Add the dashi. Then, mix the rice and seasonings well. Gently shake the pot and use your fingers to level the rice so that it‘s evenly distributed and submerged in the water.
    Hijiki Rice 8
  • Now, squeeze the hijiki seaweed one more time to drain the extra moisture. Then, sprinkle it on top of the rice in the pot. Do not mix with the rice! Next, scatter the carrot and aburaage on top. Again, do not mix with the rice. Tip: The rice will not cook evenly if mixed with the ingredients.
    Hijiki Rice 10
  • Use chopsticks to gently distribute ONLY the ingredients across the top of the rice so their flavors will release evenly. Close the lid. Let the rice soak for 20–30 minutes.
    For an electric rice cooker, choose the Mixed Rice menu, if available; otherwise, use the general setting. Then, start cooking.
    For a donabe or heavy-bottomed pot, cook on medium-high heat for about 13–15 minutes.
    After cooking, let the rice steam for 10–15 minutes. Do not open the lid during this time. This resting period is crucial for the rice to steam properly. 
    Hijiki Rice 11

To Serve

  • Gently mix the ingredients into the rice using a slicing motion to avoid mashing the rice grains.
    Hijiki Rice 12
  • Serve the Hijiki Rice in individual rice bowls and enjoy!

To Store

  • You can keep the leftovers in an airtight container and keep them for 3 days in the refrigerator or for up to a month in the freezer.

To Use the Spent Kombu and Shiitake

  • Save the spent kombu in an airtight container and store it in the refrigerator for up to a week or in the freezer for up to a month.
    Spent Kombu for Furikake
  • With the spent kombu, you can make Simmered Kombu (Kombu Tsukudani).

  • You can also use it in Homemade Furikake (Rice Seasoning).

  • For the spent shiitake mushrooms, cut off the tough stems with a knife and discard them. You can use these rehydrated mushrooms as if you are using fresh shiitake mushrooms.

I have previously prepared the hijki seaweed salad (recipe from the website) and stored in the fridge. Is it possible to create a type of mixed rice as well with these leftovers, or better to cook rice seperately and mix the hijiki afterwards in the cooked rice?

Hi, Lauren! Thank you for trying Nami’s recipes.
If you have prepared seaweed salad, you can cook the rice separately and mix it in to make the mixed rice so that Hijiki does not overcook.
We hope this helped!

This was delicious! We didn’t have the “right” kind of seaweed, so I sprinkled toasted nori on it when serving.

Hi Susan! Thank you for trying Nami’s recipe!
We are glad to hear you enjoyed the dish. Happy Cooking! 🤗

Thank you so much for the recipe! Is this something that I could prep at night and use electric rice cooker timer function for it to be ready in the morning? Or is that too much soaking time?

Hello, Shirley. Thank you for trying Nami’s recipe.
If you hydrate Hijiki for too long, it becomes extremely mushy and loses its texture. So, we do not recommend overnight soaking.
We hope this helps!

Thank you so much for a great recipe! I was wondering if there’s another way I can combine fresh tofu into this recipe? I don’t like the added ingredients in the store bought aburaage Tofu and don’t have the time to make some myself ..

Hi Shany! Thank you so much for reading Nami’s post!
You may add the fresh tofu on top of the rice when you cook them. However, when you mix it, it gets mushed into the mixed rice. So just be careful.
Thank you for trying Nami’s recipe!

Can I use fresh shiitake mushrooms instead of dried?

Also, could I use awase dashi instead? Shiitake is expensive where I live, so I buy it in small quantities, but I try to substitute when I can unless it’s essential.

Hi Teresa! Thank you so much for trying Nami’s recipe!
Yes. You may use fresh shitake and Awase dashi.
We hope you enjoy Hijiki Rice soon! 🤗

Cab you use store bought dashi? I happen to have that on hand.
Thanks

Hi Cabiria! Thank you for trying Nami’s recipe!
You can certainly use store-bought Dashi. However, it usually included a condiment like soy sauce or salt, so we recommend adjusting the amount of seasonings in this recipe to your taste.
We hope this helps!

Can this be cooked in the instant pot? What is the timing? Also, if I need to limit salt intake, can I add less soy sauce?

Hello, Susan! Thank you so much for taking the time to read Nami’s post and try her recipe!
Yes. This rice can be made in an instant pot. Please set the pressure to HIGH for 2 minutes.
More information can be found at https://www.justonecookbook.com/instant-pot-takikomi-gohan/.
We hope this was helpful!

Hi Susan! In terms of soy sauce, yes, you can use less if you prefer. You can also use less or no salt.
We hope this helps!

Favorite rice dish in all cuisines, then Tahdig.

Hi Alia! Thank you! We are glad to hear this is one of your favorite rice!
Thank you for reading Nami’s post and for your kind feedback!

This is my favorite flavor combo. Thanks for reminding me of a childhood favorite! We sometimes cooked just the veggies (usually carrots, peas, and hijiki) with a little sesame oil for another side dish. Hijiki is oishi!5 stars

Hi Dawn! We are glad to hear you enjoyed the flavor!
Thank you for taking the time to read Nami’s post and try her recipe!
Additional peas sound delicious too.😊

If I wanted to make this recipe with brown rice, would I just need to increase the soaking time in water for the rice? Like soak overnight? Thks!

Hi Blake, Thank you so much for reading Nami’s post and trying her recipe!
We recommend soaking short-grain brown rice for 6 to 12 hours before cooking, then following the recipe instructions.
We hope this was helpful!

Just made this for New Year’s celebration. My mother used to make it all the time, so it brought back memories. Everyone loved it!5 stars

Hi Amy! Aww.🥰 We are so happy to hear you and your family enjoyed Nami’s Hijiki Rice recipe.
Thank you so much for reading Nami’s post and trying her recipe!
Happy Cooking and Happy New Year!
