Product description

The most convenient way to enjoy natto

sonomono Natto Powder Capsules bring over 70 years of natto-making expertise into a modern, easy-to-enjoy form. We were the first to introduce authentic Japanese natto powder to this marketplace in 2020, and we now offer 100% pure freeze-dried natto powder in a convenient capsule. Suitable for vegan and vegetarian diets, this is a simple way to incorporate the natural goodness of natto into your daily life, without the need for preparation and strong natto scent.

Tradition meets innovation

Sonomono combines this tradition with modern freeze-drying and encapsulation, allowing the natural characteristics of natto to be enjoyed in a refined and convenient form.

Premium Non-GMO Japanese Soybeans

By supporting traditional farming with above-market payments, Sonomono helps preserve sustainable agriculture for future generations.

Spore-form, a special feature of sonomono natto bacteria

Encased in a premium plant-based capsule, the spores pass through the stomach without losing their integrity and reach the intestines, where conditions may allow them to return to their active state and support a balanced gut environment.

Authentic Japanese Quality – Crafted entirely in Japan, Sonomono Natto Powder Capsules use only carefully selected non-GMO soybeans grown with natural farming methods by experienced farmers. These soybeans are fermented with our proprietary Bacillus subtilis var. natto, a unique strain that has been preserved and studied for decades. This fusion of premium raw ingredients and traditional Japanese fermentation delivers authentic flavor, cultural heritage, and trusted quality.
Live Spore-Form Probiotics. Unlike ordinary natto, where many bacteria are destroyed by stomach acid, our unique fermentation and freeze-drying preserve the bacteria in their natural spore form. These resilient spores survive harsh gastric conditions and reach the intestines alive, where they activate and support a healthy, balanced gut microbiome.
Additives-Free. Our capsules contain only freeze-dried fermented soybean powder—no fillers, preservatives, artificial flavors, or synthetic ingredients. This pure composition ensures you receive the full natural nutrition of natto in a convenient capsule format.
Naturally Contains Vitamin K & Nattokinase. Natto is one of the richest natural sources of vitamin K2 and also contains nattokinase, both naturally occurring in fermented soybeans. Our product delivers these compounds in their natural form. If you are taking blood-thinning medications such as Warfarin, please consult your doctor before eating natto food.
Premium Japanese Ingredients – Proudly made in Japan with non-GMO soybeans, cultivated sustainably by 6th-generation farmers. By paying above-market rates, we support traditional farming practices in harmony with nature.
Innovating Food Science. Our proprietary natto bacteria strain has been studied extensively, including a peer-reviewed Nutrients (2022) publication involving 205 participants. The research confirmed its ability to survive gastric acid, reach the intestines, and promote beneficial bacteria such as Bifidobacteria and Blautia.
Easy Daily Habit. No sticky texture, no strong odor—just the benefits of natto in an easy-to-take capsule. Ideal for busy lifestyles at home, work, or on the go. Supports digestion, immune health, and overall wellness with consistent daily use in a natural way.
