The Surprising Power of
Natto Starter Spores
It Produces Nattokinase
Nattokinase is an enzyme that is produced when natto is being made.
It occurs at the stage of fermentation after adding the natto starer spores (Bacillus subtilis) after boiling the soybeans.
Nattokinase has a function of dissolving thrombus (blood clot) and make blood flows smoothly, which is now attracting much attention as an enzyme that is very helpful to improve health.
Especially, it is said to have an excellent effect on thrombolysis (the dissolution of a blood clot).
Aside for having an ability to disintegrate the fibrin (the main component of thrombus) directy, it also has a function of activating other thrombolytic enzymes in the body and increasing its amount.
In addition, recent studies have found that there are effects such as decomposing substances that inhibit the dissolution of thrombus, and shortening the decomposition time.
It can be said that it is a powerful enzyme that really enhances thrombolysis from various aspects.
Besides these all, nattokinase also has other abilities such as lowering blood pressure, and preventing blood-coagulation so the blood flow is improved.
The products which are made from soybeans are originally containing various enzymes, but among them only natto produces nattokinase enzyme.
Grow Good Bacterias In the Body such as Lactic Acid Bacteria
If you eat natto starter spores (Bacillus subtilis var. natto), it is known that good bacteria such as lactic acid bacteria (Lactobacillales) and others which is useful for our body tend to increase in our body.
Experiment result shows that the amount of lactic acid bacteria has increased about 10 times when Bacillus subtilis var. natto and lactic acid bacteria coexist.
Also, natto starter spores (Bacillus subtilis var. natto) also has the effect of suppressing bad bacteria. In addition, since lactic acid bacterias tend to increase, as a result, good bacteria are activated in the body.
We also can expect improvement of intestinal environment. The natto spores exert a remarkable effect on the intestinal action that prevents diarrhea and enteritis, and also prevents constipation by balancing the intestinal bacteria.
Besides all of these, Natto produces a lot of active enzymes in the body. It greatly contributes to digestion, intestinal control and other actions.
Why Does Natto Starter Spores Has Such Excellent Effects?
The secret of the usefulness of natto spores is its "strength".
Most intestinal bacteria in the body have short lifetime and weak nature.
Therefore, if you do not supply them frequently, you can not expect long-term successful activity in the intestines.
In exchange, the lifetime of Bacillus subtilis var. natto is long, and it is said that when it's taken once, it survives for 4 or 5 days in the body and exerts its effect.
It enters the body from the mouth, passes through the stomach acid in the stomach, reaches the intestine alive,and has the strength to be discharged to the feces without being killed in the body (still alive when being discharged in the feces).
In this way, only Bacillus subtilis var. natto which is in natto starter spores can pass through the body alive!
This is the main reason why Bacillus subtilis var. natto in natto starter exerts such excellent effects.
Frequently Asked Questions
- Can I drink it directly as it is for health?
- It is natto starter spores powder made for making natto. You can't drink it direcly.
- I heard that even the natto that is available in the market can be used as seed/starter culture bacteria of natto. Is there any need to use this natto starter spores?
- When using the ordinary natto that is available in the market as an seed/starter culture, the fermentation process won't go well because the fermentation power is weak, so the thread of the spores won't be drawn, or miscellaneous bacterias will propagate and strange smell will occur.
Kawashimaya's Natto Starter Spores Powder is a natto starter spores especially made to make natto at home.
The bacterial power is very strong, and it's a feature that it's difficult to fail even for the people who make it for the first time.
Every time you make natto, using a good quality natto starter makes it easier to make a high quality natto.
- The thread of the natto spores won't be drawn
- There is a possibility that the fermentation is not going well. Please keep the soybean (which is already added with natto starter) warm for about 12 hours.
- It's extremelly smelly. The smell is like dust cloth.
- There is a possibility that germs have propagated in the middle of the process. Please do not eat that natto. Please pay attention to the sanitation, and try again.
- The natto I made has a strong smell of ammonia
- After warming the soybean up, please put it in a refrigerator overnight. In many cases, the fermentation will stop and ammonia smell will also soften.
I usually made natto by myself using natto starter spores from the ordinary natto that available in the market.
When I use this product, I'm really satisfied to find that the color of natto changes to the color just like sold-in-market natto.
The smell of ammonia when it was finished was strong, I felt that the bacterial fermentation power of this product is very strong.
I enjoy eating the natto I made with yakiniku sauce along with it.
I can make a lot of natto with this.
I've failed to make natto with other natto starter spores before, but when I use this natto starter spores, the thread of the natto spores was nicely drawn and became a really good natto.
I will repurchase this!
I used to always use the natto starter spores from a long-established shop.
However, I have this really unpleasant feeling when I discovered that they are using the genetically modified soybeans, and extracting the natto starter spores by chemical processing.
It is disclosed in the description that this natto starter is made from organic soybean raw material and the manufacturing process is also a traditional way so I can use this safely with confidence.
My family and I really like the natto!
I'm living abroad. Even if natto is being sold here, it is expensive and I can't quite get it.
At that time, after I heard about this natto starter from a friend, I thought about trying to make it myself.
I'm really satisfied with the fact that I made lots of natto with really small amounts of natto starter.
There are also handmade natto-making methods by adding the sold-in-market ordinary natto to the steamed soybeans, but the power of the bacteria is weak so other miscellaneous bacterias is easy to enter. So, I purchased the proper natto starter spores powder.
Since then, I always successfully made natto and never fail.

How to Make Natto
【How to make natto movie】
1.Wash the beansPut the beans into a bowl and wash them well by rubbing them together.
Be careful not to break the skin.
Soil and other impurities on the surface of soybeans has tons of microorganisms that have adverse effects on making Natto.
Make sure to wash off all the dirt and debris.
2.To Soak the washed soybeans in waterSoaking time differs depending on the season In spring and autumn, you have to soak the beans for 15 hrs on 10-15 degrees celsius water temperature.
In summer you have to soak the beans for 6 hrs on 20-25 degrees celsius water.
When the temperature is too high cover the bowl with plastic cling wrap and leave in the fridge for about 24 hours.
The beans expand about 4 times more than the soybean weight.
(500g of soybeans uses 2L of water)
3.Boil the beansBoil it till it easily squashes by nipping with thumb and index finger.
The beans will have slightly hard texture when fermentation starts,
so make sure to boil them until tender.
It takes approx 30 mins for a pressure cooker to cook.
(The result may vary depending on a cooker. Please refer to the instruction manual for the exact cooking time)
4.Dissolve Natto starter into water and make“Natto solution”Pour 10ml of water
(pre-boiled and then cooled water is fine too)
in a cup and dissolve 0.1g of Natto starter
(one fifth of small spoon) in it.
Use this Natto solution to ferment the beans.
It is easier to succeed with more Natto solution.
For the first timer, using greater amount than this recipe is recommended.
5.To pour the Natto solution over the beansDiscard the boiled water.
Then in no time, pour the Natto solution and mix thoroughly.
Don't let the temperature to drop,
as it can lead to unwanted bacterial contamination.
Prepare to pour the Natto solution as soon as the beans are boiled.
Transfer the beans from the pot to a foodwarmer such as a Yogurt Maker.
I'm using a food warmer function of the pressure cooker Please Keep the soybean mixture in a warmer for 24 hours to ferment.
The best temperature for Natto solution to ferment is 40 to 45 degrees celusius.
Keep the temperature steady at 45 degrees and set the timer for 24 hours when using a food warmer.
I kept the beans warm for 24 hours Let's check the fermentation condition It looks well fermented however it has a strong ammonia smell at this point.
6.to let the fermented nattocool in the fridgeTransfer the fermented beans to refrigerator to mature
By resting the beans in a fridge for a day,
amino acid composition of soy protein will enrich the flavor of Natto.
Let’s see how the natto is after resting it overnight
It is perfectly fermented and there is no smell of ammonia.
Tasty Natto is now ready to be served.
In this video I used 165g of soybean The finished natto weighs 721g
If you are not planning to eat immediately, keep it in a freezer.
If you leave the natto in a place where the temperature is high amino acids are broken down and cause ammonia smell.
When it is stored in the fridge, a white rough stuff will start to grow which will give it a bad texture in a week or so.
The taste and flavour of natto differs greatly depending on the fermentation time and the types of soybean.
You can decide on what type of soybean and how long you want to have it in fermentation.
