Try the original whole natto made with Japanese soybeans.
Natto is a traditional Japanese food made by fermenting soybeans with Bacillus subtilis. For more than 1000 years, Japanese people have eaten natto to support health and longevity.
Even if natto is a superfood loaded with nutrients and probiotics, its slimy texture and pungent smell make it difficult to eat with other foods. Sonomono solved this problem by freeze-drying and powdering natto. The freeze-drying preserves all the nutritional value of natto and allows the efficient intake of natto bacteria that reach the intestines alive.
The quality of natto starts from the soy, we solely use non-GMO Japanese soybeans, cultivated without chemical pesticides or fertilizers by the Kohoku Town Organic Study Group in Saga Prefecture.
Use natto powder to add umami to your food. We have two types of natto powder: “regular and mild.” Both are convenient for baby food and long-term care food because, compared to raw natto, our fine powder is easy to chew and swallow. The “regular” type is great for enhancing food flavors and adding a thicker texture. The “mild” type is recommended when you want to add just a subtle flavor and a slightly natto smell to your food.

kona-natto

Many people wonder, what are the health benefits of natto? The key to reinforcing the barrier power is improving intestinal activity. The increase of good bacteria improves the intestinal environment. A recent discovery points out that more than 60% of the immune cells reside in the intestine. Those cells’ function is to protect us from viruses and other nocive organisms. Maintaining a healthy intestinal environment leads to an increase in barrier power. Natto is an optimal food for intestinal health; it contains billions of Bacillus subtilis or “natto bacteria” that help to normalize the intestinal environment. The main difference between natto powder and other fermented food is that it contains natto bacteria in spore form. A spore is a natural cell structure that confers resistance to heat and dryness. Thanks to its spore, B. subtilis can pass through the gastric acid and reach the intestines unharmed.
Once in the intestines, B. subtilis assist digestion, absorption of nutrients, and stimulate the immune system. It also helps other beneficial bacteria in the intestines to proliferate and improve the intestinal environment. When the amount of good bacteria exceeds the harmful bacteria, the microbiota enters into balance and the digestive and immune systems can perform their functions properly.

According to several estimations, more than 1000 types of intestinal bacteria coexist in our intestines, ranging from 600 to 1000 trillion. The ideal proportion between good and harmful bacteria is 2:1, which means 20% of the intestinal space could be occupied by good bacteria, and 10% by harmful bacteria. The remaining 70% f the intestinal space is occupied by opportunistic bacteria that can support the growth of either good or bad bacteria. If the population of intestinal good bacteria is greater than bad bacteria, thence the opportunistic bacteria will side with the good bacteria. For this reason, it is essential to maintain the 2:1 proportion.
What’s kona natto?
Bacillus subtilis grows naturally on rice straws. One of its survival mechanisms in hostile environments is forming spores. A spore is a resistant shell able to stand hot water at 100 degrees for more than 10 minutes, survive in a vacuum, and acid environments. This natural shield allows B. subtilis to pass through the gastric acid and reach the intestines alive.
Sonomono natto powder contains B. subtilis in spore form, use it to supply your body with a daily dose of probiotics.

In babies, the gut is initially filled with Bifidobacteria shortly after birth, but as they begin to eat solid food, the composition of gut bacteria changes. Furthermore, it’s not uncommon for the balance of gut bacteria to shift dramatically in people aged 40 and older, with an increase in harmful bacteria and a decrease in Bifidobacteria.
Various gut bacteria coexist and support each other within the gut. In recent years, there has been a growing emphasis on the idea that having a diverse range of bacteria in the gut is beneficial, so it’s important to strive for a balanced diet that includes a variety of foods.
※From 2020 to 2021, we conducted a study monitoring the gut microbiota of 205 participants who consumed freeze-dried powder capsules containing natto bacteria (Sonomono natto bacteria, Bacillus subtilis var. natto SONOMONO) over two months. Analysis was conducted using the SYMGRAM® gut microbiota test kit for healthcare institutions, operated by Symbiosis Solutions Co., Ltd.

The safety of our clients is our top priority. We exclusively use soybeans from the Organic Research Group in Kohoku Town, Saga Prefecture. This farmers’ association cultivates a native variety known as Fukuyutaka, famous for its fluffy grains and high nutrients content. * The soybean production area may change due to natural disasters.

Making Japanese natto is an art and science. The ingredients are simple: soy, water, and bacteria. However, it requires time-tested techniques and experienced hands to achieve the great flavor that makes our natto powder famous all over Japan.
Reliable process that preserves natto probiotics and nutrients.

We use selected soybeans, rich in high-quality proteins and fatty acids that provide comprehensive nutrition for your body.

The fermentation produces enzymes and other substances unique to natto. It also increments soy nutrients and their absorption rate.

Freeze-drying is a process that removes natto’s moisture by applying ultra-low temperatures. It preserves the soy nutrients and induces the formation of spore bacteria.

The fine powder can easily dissolve in food, allowing fast intake of natto nutrients and probiotics.

INGREDIENTS
Coffee and sonomono natto powder.

3. Stir the milk and natto into your coffee and enjoy. You can sprinkle cinnamon or decorate it with caramel syrup.
There are two types of natto powder: regular and mild. Both contain the same amount of probiotics and nutrients; the difference resides in the aroma and flavor. We recommend REGULAR if you are accustomed to natto’s intense aroma and flavor, and enjoy natto at 100%. If you are new to natto or tried it before but are afraid of its smell and stickiness, we suggest trying MILD.
※If you want to compare both, we recommend buying the trial set.

Wu/Taiwan NEW
Hello everyone, I’d like to share my personal experience with sonomono Inc. They recently launched an innovative portable natto product, which is incredibly convenient. We all know natto is rich in nutrients, but its strong smell and storage challenges have made it difficult to enjoy outside Japan. As someone who travels as frequently as others ride bicycles, I was immediately thrilled when I saw sonomono Inc’s natto products and felt a deep sense of gratitude.
I ended up purchasing almost all of their natto-based products, including the crackers. At this moment, I’m also enjoying their mulberry leaf tea powder—it’s my first time trying it, and it definitely meets my expectations.
Being a foreigner, sonomono Inc assigned me a customer service representative named Giovanny Paiz. Initially, I simply admired sonomono Inc’s products, but I want to express my appreciation for Giovanny Paiz. Not only did he display the thoughtful service attitude I associate with Japanese culture, but I also discovered through our interactions that he has genuine empathy, always thinking of solutions for his customers.
In other words, Giovanny Paiz promptly solved my problem by proposing better options. His proactive attitude truly stood out and turned my admiration for sonomono Inc’s products into an even deeper appreciation for their excellent customer service. Since I don’t have a direct channel to reach the higher management at sonomono Inc, I decided to take this opportunity to share my experience.
I want to let other consumers and the company know that sonomono Inc’s products are exceptional and have touched my heart. But the outstanding service provided by Giovanny Paiz may very well be one of the main reasons I look forward to purchasing from them again. Thank you so much, sonomono Inc, for assigning Giovanny Paiz as my customer service representative, and I sincerely hope the company will commend or reward him! I am truly grateful.
With Gratitude
Totally satisfied with the product.
My family and I have been taking the natto every day (1 tablet) for a little over a month now.
We have all noticed a big difference in our gut health with less gas and bloating and finding it easier to go to the toilet. Some family members have noticed that their hormones have been more balanced since taking the Natto. We have all noticed a difference in the health and appearance of our skin. All very positive results and we are so happy to be able to use this product. We would give it 5 stars .
Easy to carry, it’s handy!
Overseas stores only sell frozen natto. The flavor is different, and it is troublesome to thaw it, so I don’t like it. Natto powder is tasty. It has a pleasing aroma, stickiness, and because of the resealable pouch, it’s easy to carry.
Love it with miso soup!
Natto soup made by adding natto to miso soup is a breakfast staple at my home, but sometimes I forget to buy fresh natto. I can easily use natto powder instead of raw natto in my miso soup and tastes great. What a valuable and tasty product!
I always bring it in my lunch box.
It’s delicious whether you sprinkle it on rice for lunch at work or put it in miso soup. It’s also safe. In summer, food spoils quickly. Because this powder is freeze-dried, it won’t rot. I can use it with peace of mind.
Unbeatable for adding natto nutrition!
It is handy because you can easily add natto’s savory and nutritional benefits to food. I enjoy sprinkling it on breakfast or with ochazuke. As a mom, I appreciate the simplicity and safety of this product. I will continue using it.
