What is Natto?

What is Natto?

Natto is a traditional Japanese food made from fermented soybeans. Fermentation is the process of converting carbohydrates to alcohol or organic acids using microorganisms (yeasts or bacteria) under anaerobic conditions. In natto, it uses Bacillus subtilis bacteria to be fermented.


Natto has sticky and slimy texture, strong flavor, and rather strong smell.

A lot of people love natto, but there are also many people who dislike it.

For you who haven't tried it yet, please try by all means!

In Japan, natto is very popular.

We can say that all Japanese know natto.

Japanese people usually eat natto as breakfast food.

In addition, natto is unexpectedly good for your health. It has many nutrients in one serving. This tiny, sticky little thing will keep you healthy if you consume it!

Some of the benefits are they improve your food digestion, as a defense against toxins and harmful bacteria, and can help reduce gas, constipation, and bloating.

Good for the Skin
Natto is rich of a vitamin known as pyrroloquinoline quinone (PQQ), which is people little-known about, that is important to maintain healthy, beautiful skin.

Contains A Lot of K Vitamins
Natto is abundant with vitamin K. You can find vitamin K1 in many green vegetables such as spinach. However, another important K vitamin, vitamin K2 is not as easy to find. Vitamin K2 is produced by bacteria, and natto happens to be rich of it. Vitamin K2 delivers a wide range of health benefits, such as maintaining bone density, supports bone health by increasing bone mass and slowing boneloss, and is associated with lower risk of heart disease, artery calcification and death.

Customer's Reviews

Tried it for the first time!

I always wanted to try to make natto and finally, I can make it myself for the first time.

I boiled the soybeans and sprinkled the starter spores powder as the instructions said, and voila! The natto is ready!

The soybeans are really delicious. I've never tasted a natto as delicious as this before.

I've used all the soybeans from this kit's package but there's still a lot of spores powder left. I think I'll make nattos from other kind of soybeans next.


Easy to Make

I'm impressed that the natto was much easier to make than I thought.

I feel that the power of fermentation is spendid.


I made a very tasty natto!

I really love natto so I've tried a lot of kinds of natto before, but this is the first time I tried homemade natto.

Maybe because I gave a lot of love when I made it, it became the most tasteful natto I've ever eaten.


A natto to my liking.

I successully made a delicious natto.

I prolonged the fermentation time, and the natto became tasty as I liked it.

I will continue to enjoy making natto.
