Why Natto Is Japan’s Most Underrated Superfood—for Health, Beauty, and Everyday Life

Discover why natto is Japan’s top superfood for health and beauty. Packed with protein, vitamin K2, and probiotics—it's affordable, powerful, and easy to enjoy daily.

When people hear the word “superfood,” they often think of trendy imports like chia seeds, quinoa, or acai berries. But for those in Japan—and for anyone looking for a nutrient-rich, affordable, and easy-to-eat health food—there’s a native option that’s been around for centuries: Natto.

 

This sticky, fermented soybean dish may look unusual, but it’s packed with a unique combination of nutrients and health benefits that set it apart from other superfoods.

🌿 What Makes Natto a True Superfood?


Natto is made by fermenting soybeans with Bacillus subtilis (natto bacteria), which transforms plain soybeans into a powerful, living food rich in:

Plant-Based Protein

Essential for muscle repair, hormone production, and skin regeneration.

Vitamin K2

Crucial for bone health and calcium absorption. Natto is the richest known food source of this vitamin.

Vitamin B2

Supports healthy skin, energy metabolism, and cellular repair—making it a go-to for beauty from within.

Nattokinase

A unique enzyme produced during fermentation that is believed to help maintain healthy blood flow and reduce clotting risk—an effect not found in most other superfoods.

Polyglutamic Acid

A naturally moisturizing and immune-supporting substance formed during fermentation.

Dietary Fiber

Helps improve digestion and maintain a healthy gut microbiome.

💫 Beauty and Wellness in a Single Bowl

Especially popular among health-conscious women in Japan, natto is often called a “beauty food” thanks to its:

  • Antioxidant and anti-aging properties
  • Support for hormone balance
  • Role in healthy, glowing skin

It’s a rare food that supports both internal wellness and external appearance—without the need for pills or powders.
