3 Types of Natto: Whole Beans, Hikiwari, and Goto Natto

Natto is known for its sticky texture and strong smell, but did you know there are different types? In this post, I’ll introduce three types of natto. If you’re curious to learn more about natto, keep reading!

Different Types of Natto

This sticky, stringy natto can be divided into three types: Marudaizu Natto (Whole soybean), Hikiwari Natto (Chopped soybeans), and Goto Natto. Here’s a closer look at each one!

Marudaizu Natto (Whole Soybean Natto)

When people think of natto, they usually refer to Marudaizu Natto, the most common type made by fermenting whole soybeans. It’s further classified by bean size—large, medium, small, and extra small—offering a variety of textures. There are also different variations based on the type of soybeans used and the accompanying sauce.

With its plump, hearty texture, this natto lets you fully savor the beans’ natural flavor.

Hikiwari Natto (Chopped Soybean Natto)

Hikiwari Natto is made by chopping soybeans, removing the skins, and fermenting them. Compared to whole bean natto, its larger surface area promotes more active fermentation, resulting in a stronger aroma and a stickier texture.

Since the skins are removed, it has a softer texture and is easier to digest.

Goto Natto (Natto with Rice Koji)

Goto Natto is a unique type of natto made by fermenting hikiwari natto with rice koji and salt. Unlike regular natto, it undergoes two fermentation processes—first with natto bacteria and then with rice koji. It’s similar to making miso, but instead of whole soybeans, natto is used!

This traditional fermented food has been made in Yamagata Prefecture for generations. With its longer shelf life, it has been valued as a preserved food in local households.
