My mom used to recite a Japanese proverb, ‘Miso soup is the medicine for eternal youth and longevity’ (miso shiru wa furou chouju no kusuri), which literally means “Miso soup is medicine for eternal youth and longevity,” at the dinner table. It was probably her way of making sure we finished every drop of the miso soup she served with the meal.
The kotowaza (proverb) was a bold claim, but it really captures the power of miso soup and its importance in Japanese culture. If you wish to discover more, I have this recipe for Natto Miso Soup with Okraone of the most nutritious soups for you to try!
Natto Miso Soup’s Health Benefits
Natto miso soup, also known as natto-jiru (納豆汁), is a popular style of miso soup featuring chopped natto with one or more types of vegetables. If you’ve only tried natto on its own or with rice, adding natto to miso soup is another delicious way to incorporate fermented soybeans into your diet.
In Japan, foods with a slimy texture are known as heaven heaven (ネバネバ) and are considered nutritious and good for strengthening the body and recovering from fatigue, especially to help prevent summer fatigue. These slimy foods such as okra and natto are are high in fiber, antioxidants, and minerals.
The slightly bitter tang of natto complements the creamy savoriness of miso soup, and its slimy texture tends to dissipate in the broth. In this recipe, I added okra to give the soup an extra boost of texture, color, and nutritional value—okra is rich in vitamins A and C, folate, as well as antioxidants and minerals like magnesium!

How to Make Natto Miso Soup with Okra
- Make the dashi (Japanese soup stock): Add water and dashi packet to a medium saucepan. Cover and bring to a boil. Reduce the heat to medium low and cook, covered, for 2–3 minutes. Then, discard the dashi packet.
- Cook the ingredients: Add okra and natto to the simmering dashi. Let it cook for one minute. Turn off the heat.
- Add the miso and serve: Stir in the miso paste until dissolved. Taste and adjust. Serve the soup in individual soup bowls, and enjoy!
Recipe Tips
- Make dashi using a dashi packet or prepare it from scratch. I always recommend avoiding dashi powderespecially when making miso soup, because the flavor is much weaker.
- Be careful when you slice the okras with a knife as they can get slimy.
- Do not let the soup boil after the natto and miso are added. Turn off the heat when it is hot enough and do not simmer for a long time, or else the nattokinase bacteria will perish.
- (Ground) toated sesame seeds add a nice aroma and texture to the soup, but it’s optional.
How to Store
I highly recommend consuming the miso soup immediately because it will lose its aroma and taste over time. Since this miso soup is so easy to make, it’s best to make it from scratch when you need it.
If you happen to have some leftovers, cool the soup to room temperature (no longer than 4 hours), store in an airtight container, and keep for up to 2 days in the refrigerator or 2 weeks in the freezer. When ready to use, reheat in a pot over medium heat, but do not boil.
What to Serve with This Miso Soup
As it takes minutes to prepare, I enjoy making this natto miso soup to go with my leftovers lunch. It is also excellent as part of your dinner, especially in an Ichiju Sansai (one soup, three dishes) format.

Instructions
To Make the Dashi
-
To a medium saucepan, add 2 cups water and 1 dashi packet.
-
Start cooking over medium heat and bring it to a boil. While waiting, you can prepare the other ingredients (go to the next step). Once boiling, shake the bag a few times to release more flavor into the soup. Reduce the heat to medium low and simmer for 2–3 minutes. Then, discard the packet. Your dashi is now ready to use.
To Make the Miso Soup
-
Meanwhile, prepare the ingredients. Cut off the stem ends from 2–3 okra. Then, cut the okra crosswise into thin slices.
-
Empty 1 pack natto (fermented soybean) onto your cutting board. Run your knife through the natto to chop the soybeans into small pieces.
-
To the simmering dashi, add the okra and natto to the saucepan.
-
Cook for 1 minute, stirring occasionally.
-
Turn off the heat. In a ladle, stir 2 Tbsp miso into some hot stock using cooking chopsticks to completely dissolve, then release it to the soup. Alternatively, you can use a fine-mesh miso strainer and/or a miso muddler to dissolve it faster. Next, taste the soup and add more miso if needed. If it‘s too salty, add water or dashi (if you have any) to dilute. To serve, pour the miso soup into individual bowls. Optionally, sprinkle (ground) sesame seeds for the aroma and texture.
