What is Natto?

Natto is fermented soybeans and traditional Japanese food. It is a healthy food eaten all over Japan and popular breakfast food.
If you stay in a Japanese-style hotel in Japan, most likely, Natto will be on the breakfast menu.
The traditional way is Natto Gohan: Put Natto over a bowl of steamed rice and add some topping such as green onions (Some people eat it with a raw egg).
What does it taste like?
Natto is slimy, gooey, and sticky, but it's not rotten; it's fermented.
I grew up eating Natto, so the strong smell and slimy texture don't bother me, but if you try it for the first time, the smell and texture can be off-putting.
If you eat Natto without anything, you might taste it sweet slightly, which is the taste of soybeans and umami (savory) from fermenting.
Natto usually comes with a natto sauce (a mixture of dashi, soy sauce, and sugar) and karashi (Japanese mustard), and these condiments make it sweet and savory.
But anyway, it is hard to describe the taste, so you have to try and experience it yourself.
You might like it or hate it, lol.
How is it made?

Natto is made from soybeans and natto-kin.
Natto-kin is a type of bacteria, and the Natto's stringy texture is made by the natto-kin breaking down soybean proteins.
By the way, Natto used to be made by wrapping in rice straw since natto-kin lives in it.
Here's how it's made:
- Rince soybeans
- Soak soybeans in water
- Steam soybeans
- Spray natto-kin (bacteria)
- Ferment
You can watch the process in this video: How to make Natto in a factory.
How to make it at home
Can I make it at home? It takes time and requires some cooking utensils, but YES you can!
You will need soybeans and natto starter: Natto spores.
This video, "How to make natto at home," shows you how to make it at home.
Natto packs

Like the picture above, Natto is usually sold at stores in three packs together.
The individual pack is in styrofoam containers and comes with natto sauce and karashi mustard (Japanese mustard). One package is for one serving which is about 50g.
If you open the pack, it's covered with transparent film to prevent the Natto from drying out.
Where to buy Natto?
You can find it easily at a grocery store or convenience store in Japan. Like the picture above, it's three packs together, and the price is about 100yen (less than $1).
The most popular brand is okame Natto (the one with a woman's face in the picture above).
You can find it at Asian grocery stores or Japanese supermarkets if you live outside of Japan. You would find it around the tofu section or frozen section.
You can also find it at online stores: Japanese center and Walmart.
Types of Natto

You can find many types of Natto in Japan, but in this section, I share three different types by the size of the bean.
#1 XS and S size
This bean size is the most popular one eaten at home daily. It is close to the rice grain size, making it easy to eat with rice and mix.
#2 M and L size
Beans are larger than S size, and they are chewier. You can enjoy the texture and flavor of the fluffy beans.
It's good to eat as it is and suitable for soup.
#3 Hikiwari natto (crushed Natto)
Hikiwari natto is made by crushing soybeans, removing the skin, and fermenting.
Fermentation time takes less, so it tastes slightly different from not crushed Natto. It has a soft and smooth texture.
Since there is no skin, dietary fiber is less and easier to digest, so it's suitable for small children.
It's often used for natto maki (sushi rolls).
Is Natto healthy? (Natto Benefits)

Natto has a unique smell and strong flavor, but it's also a superfood with many health benefits.
It's packed with soybean's rich nutrients, and the nutrients are further increased by fermentation.
It is rich in:
- Protein
- Minerals (potassium, magnesium, iron)
- Dietary fiber
- Vitamins (B vitamins, vitamin E, vitamin K2)
- Natto kinase
- Natto-kin

Natto has various health benefits, but nattokinase and natto-kin have significant effects.
Nattokinase
Natto contains an enzyme called nattokinase, which helps break up blood clots and blood flow smoothly. Thanks to that, it also prevents vascular diseases, so it is recommended to eat Natto every day.
It's hard to know what's going on inside your blood vessels. But if Natto keeps it healthy? Then let's eat it and be healthy.
By the way, nattokinase doesn't like high temperatures and will be lost when heated above 70C, so if you want to get the benefit, the best way is to eat as it is (without cooking).
So, when you eat Natto Gohan (Natto rice), it's better to let the rice cool down a little before eating (avoid the rice right after cooking).
Natto-kin
Natto-kin contained in Natto is a type of good bacteria that keeps your gut healthy.
When your gut works actively and healthy, bowel movement is improved, boosts your immune system, and prevents you from getting sick (immune cells are concentrated in your gut).
Gut health is a significant factor in our ability to absorb the nutrients we need. If your gut functions correctly, it will block harmful substances and make digestion easier!
Fortunately, heating natto doesn't kill this natto-kin, so you can cook it and still get the benefit.
Eat Natto and be energetic!
How to prepare Natto
Let me show you how to prepare Natto. You can also watch this video.

Natto comes with natto sauce and karashi mustard (Japanese mustard). One pack is for one serving which is about 50g.
- Open: Open the natto pack, and you see the sauce and karashi mustard on the top.
- Take the transparent film: Put aside the sauce and karashi mustard and take the transparent film on top of the Natto.
- Sauce and karashi: Pour the sauce and karashi over Natto.
- Stir: Stir with chopsticks until smooth, about 10 to 20 times.
Stir more to increase umami

If you stir Natto many times, you can taste umami (savory taste) more.
An article scientifically proves that if you mix well, the umami score will increase, and if you add the sauce several times separately, the taste will be better.
The method from the article:
- Mix 400 times
- Add the sauce after mixing
- Add the sauce multiple times (not at once)
I've tried it, and see the photo below. The left image is stirred 20 times, and the right image has followed the method and is stirred 400 times.

You can see white gooey stuff around the Natto in the right photo. It is more fluffy and soft as it contains more air and tastes better.
Also, it's less stringy, so easier to eat.
Stirring 400 times is work! But if you want more umami, please give it a try!
How to store Natto
The fermentation process continues at room temperature, so storing it in the fridge or freezer is essential.
It will last for about one week in the fridge and one month in the freezer.
Please leave it in the fridge for a half-day to defrost when eating frozen Natto. Please do not use a microwave oven as it ruins the taste.
Does Natto go bad?
It might generate a foul smell when exposed to 10C (50F) or higher for a long time.
Even after the expiration date, you can eat it (I sometimes do), but the smell will get stronger, and the tastes will get bitter, so it's better to eat it within the date on the package.

Natto FAQ
Yes, you can eat it straight from the package (I sometimes do), but I recommend cooking with other ingredients if you're new to Natto. (See: "Natto Recipes: 8 Tasty Ideas" in this post)
It would be hard to try Natto for the first time because you might not like the gooey texture and strong smells. Mixing it with something that tastes stronger, such as vinegar, garlic, or Kimchi, would help. Also, cooking it with other ingredients will help make things easier, such as Natto Omelet and Natto Chahan.
If you stir Natto many times (400 times), you can taste umami (savory taste) more. (see: "Stir more to increase Umami" in this post) It is more fluffy and soft as it contains more air and tastes better. Also, it's less stringy, so easier to eat. Stirring 400 times is work! But if you want more umami, please give it a try!
Please keep it in the fridge, which will last about one week. You can also store it in the freezer for about one month.
Natto is slimy, gooey, and stinks, but it's not rotten. It's fermented. I grew up eating Natto, so the smell doesn't bother me, but if you try it for the first time, it might be challenging to deal with (please don't be scared!!).
Natto usually comes with a natto sauce (a mixture of dashi, soy sauce, and sugar) and karashi (Japanese mustard). These condiments make it sweet and savory.
If you eat Natto without sauce, you might taste it sweet slightly, which is the taste of soybeans and umami (savory) from fermenting.
If you stir Natto, It is more fluffy and soft as it contains more air and tastes better.
It might generate a foul smell when exposed to 10C (50F) or higher for a long time. Even after the expiration date, you can eat it (I sometimes do), but the smell will get stronger, and the tastes will get bitter, so it's better to eat it within the date on the package.
I usually have one or two packs daily (one pack is about 50g). Two packs per day are good enough. But if you consume soy products daily like tofu and soy milk, one pack a day would be appropriate.
