1. Natto Benefits: A Personal Encounter with Natto
I still remember my very first bite of natto.
It was during a winter trip to a small hot-spring town in Japan. At breakfast, I noticed a tiny styrofoam pack filled with sticky soybeans. When I stirred it, threads stretched out endlessly. Honestly, I hesitated. The strong smell and gooey texture weren’t exactly welcoming.
But then, my Japanese friend smiled and said:
“Don’t underestimate it. My grandmother eats natto every morning. She’s in her nineties, still strong and healthy, and her doctor always jokes that natto is the real medicine.”
Back then, I thought it was just a local belief. Years later, I discovered studies proving that what looked like sticky strings actually carried a treasure—nattokinase, vitamin K2, probiotics, and powerful antioxidants.

2. A Thousand Years of History
Natto’s roots go back a thousand years, when Buddhist monks accidentally fermented soybeans wrapped in straw. What started as temple food spread to samurai households and eventually became a staple in ordinary kitchens.
Today, natto is one of the most common breakfast dishes in Japan. On average, a Japanese person eats about 40 packs per year, and convenience stores stock them like bread or milk. The tradition has even reached the West, where natto is now recognized as a superfood alongside kimchi and kefir.

4. Health Benefits of Natto
🫀 Heart & Circulation
Nattokinase has a rare ability—it can dissolve fibrin, the protein that forms blood clots.
A study from Osaka University showed that people who ate natto at least three times a week had a 30% lower risk of stroke compared to those who rarely consumed it.
🦴 Bone Strength
Vitamin K2 in natto acts like a traffic guide, sending calcium to bones instead of leaving it in arteries.
A large-scale survey of 1,200 women in Kyushu revealed that the group consuming natto consistently had significantly higher bone density.
🌿 Digestive Health
The live Bacillus subtilis bacteria in natto reach the intestines and encourage beneficial gut flora. This improves digestion and relieves constipation.
🛡️ Immunity & Anti-Aging
Isoflavones and antioxidants in natto reduce cell damage, helping the immune system defend against infections and lowering inflammation.
✨ Skin & Beauty
Polyglutamic acid, unique to natto, helps skin retain moisture. According to the Japanese Society of Aesthetic Dermatology, natto extract increased skin hydration levels by 12% in a controlled trial.

7. KORI’s Recipe 👨🍳
Here’s my favorite way of enjoying natto—the Kori Natto Rice Bowl. It’s simple, comforting, and perfect for busy mornings.
Ingredients (1 serving):
- 1 pack natto

- 1 bowl warm rice
Steps:
- Place natto on top of hot rice.
- Crush the roasted seaweed and sprinkle generously.
