Kawaguchi Natto began in a small Japanese town renowned for its traditional natto craftsmanship. Faced with the global challenge of making this potent superfood accessible without the strong smell and texture, our head researcher, a 3rd-generation natto maker, pioneered a freeze-drying method. We selected only non-GMO soybeans from local farms and use a proprietary strain of Bacillus subtilis natto, cultivated in our GMP-certified facility in Osaka. Every batch is tested for Nattokinase potency (FU) and purity. This commitment has made it the top-selling freeze-dried natto in its category in Japan for three consecutive years, trusted by over 200,000 households.

Kawaguchi Freeze-Dried Natto Beans 180g is a premium Japanese superfood that primarily contains high-quality soybeans, which undergo a fermentation process using Bacillus subtilis var. natto, a specific bacterial strain essential for producing natto's characteristic texture and nutritional profile. This fermentation process is key to the product's inclusion of natto kinase, an enzyme that aids in promoting cardiovascular health by supporting healthy blood circulation and potentially reducing clot formation. Additionally, the freeze-drying method preserves the beans' natural probiotics, which contribute to gut health by maintaining a balanced microbiome and enhancing digestion. The product is rich in protein, providing essential amino acids for muscle maintenance and overall bodily function, and contains vitamin K2, derived from the fermentation, which plays a crucial role in bone health by aiding calcium absorption and reducing arterial calcification. Other beneficial components include dietary fiber for digestive regularity and antioxidants that help combat oxidative stress. By utilizing freeze-drying, Kawaguchi ensures that these ingredients retain their potency and bioavailability without the need for preservatives, making it a convenient and health-focused option for consumers seeking the traditional benefits of natto in a shelf-stable form.
