Origin of Natto Jiru in Yokote City

Long ago, around 1083-1087, a farmer in Akita Prefecture wrapped boiled beans in straw to help soldiers in a war. Those beans turned into natto over time because of their special smell and taste. This natto became a local favorite, and people in Yokote City made a soup with it called Natto Jiru. There’s even a monument in Kanazawa Park in Yokote City that honors this legend.

People have been eating natto soup for a very long time. Sen no Rikyu, a famous person, served natto soup seven times in his tea ceremonies. Even Hideyoshi Toyotomi, another important person, enjoyed natto soup at these gatherings. In old times, during the Edo period, natto soup appeared in books and was eaten in different parts of Japan, not just in Akita.

Natto Jiru in Everyday Life

In the past, people described how they made and ate natto soup in Edo. Sometimes, when veggies were hard to find, they used natto to make up for it. In Edo, there were people who sold ingredients for natto soup. They made it easy for everyone by selling “knocked natto,” which was like instant miso soup—all you needed was hot water and some other things to make the soup.

Natto soup wasn’t just food. It became a big thing in people’s lives. There were sellers who sold natto ingredients early in the morning. Poems called senryu often talked about them, showing how much a part of daily life they were. In Edo, natto soup was more common on tables than natto rice itself. It was more than just a dish—it became a part of how people lived and shared their culture.

Health Benefits of Natto Soup

Anti-aging effect

People can find Polyamine in soybean products. It helps with anti-aging by supporting things like long life and fixing cells. But as we get older, our body finds it hard to make enough of it.

Natto has this polyamine, and so does miso, which is made from the same stuff as natto. So, by eating both, you can get more of it, and they work together to give extra benefits.

Improving Immunity through Gut Health

This thing has oligosaccharides that help increase good bacteria called bifidobacteria in your gut. These are famous for fighting constipation. They feed these bacteria, making your poops healthy, which tells a lot about your health.

Healthy poops aren’t just about color and shape. They don’t smell strong, and there’s nothing left after you go. Good poops don’t just help with constipation. They also make your gut healthier, which boosts your immunity.

Enhancing Your Diet

Soy saponins help your body make more adiponectin. Adiponectin is made by fat cells and helps stop arteriosclerosis and diabetes. It also helps burn fat.

When you mix soy saponins with some exercise, you’ll likely see even better results.

Lowering Cholesterol

Soy lecithin helps bring down the total cholesterol in your body. It’s part of HDL, which is a good type of fat that helps cells grab onto nutrients and removes extra cholesterol from your blood vessels.

Since it helps fight diseases linked to how we live, it can help with things like high blood pressure as we get older.
