Natto: The Ultimate Guide for Newcommers

The Japanese Superfood You Need to Know About

If you’ve ever explored Japanese cuisine beyond sushi and ramen, you may have come across natto, a traditional fermented soybean dish celebrated in Japan for its extraordinary health benefits. For many in the United States, however, natto remains a mystery. What exactly is it, how does it taste, and what makes it so unique? This guide is designed for health enthusiasts, gourmets, and curious eaters ready to expand their culinary horizons.

Traditionally eaten for breakfast in Japan, natto is often served over steamed rice, accompanied by garnishes such as soy sauce, mustard, or green onions. Its cultural significance is vast, as it has been consumed for centuries and is celebrated for its potential cardiovascular, digestive, and immune system benefits.

What is Natto?

At its core, natto is fermented soybeans. But calling it “just soybeans” does not capture the full story. Natto is created through a meticulous fermentation process using Bacillus subtilis var. natto, which transforms ordinary soybeans into a sticky, nutrient-dense powerhouse.

Its cultural significance is vast, as it has been consumed for centuries and is celebrated for its potential cardiovascular, digestive, and immune system benefits.

Nutritionally, natto is remarkable: rich in protein, probiotics, vitamin K2, and bioactive compounds like nattokinase, which may support heart health and circulation. It is a true superfood, particularly appealing to those committed to gut health and functional nutrition.

Taste and Texture: What Does Natto Actually Taste Like?

Describing natto to someone who has never tried it can be tricky. Its flavor is complex, layered, and unlike any other soybean product.

  • Taste: Natto has a strong, nutty umami flavor with a pronounced earthy depth. Some describe it as savory and slightly cheesy, reminiscent of aged cheese or miso, with a subtle bitterness that lingers pleasantly. There’s a faint sweetness that comes through when the beans are fresh.
  • Texture: The beans themselves are soft yet firm, while the sticky, stringy mucilage, a hallmark of high-quality natto, adds a chewy, almost elastic mouthfeel that can be surprising to first-timers. It’s this sticky texture that often intimidates newcomers, but it is part of the authentic experience.

Aroma: The Smell of Natto

Natto’s aroma is polarizing. For many, the smell is the first hurdle to overcome. It has a distinctive pungency that combines fermented cheese, soy, and a hint of ammonia. It’s not unpleasant per se, but it is strong and can take getting used to.

Seasoned natto eaters often say that the aroma mellows once the beans are mixed and garnished, and the taste far surpasses the initial olfactory shock. For adventurous eaters and food connoisseurs, this is part of its charm—a bold aroma signaling a potent nutritional profile.
