From teaching to farming with a desire to cherish food

I taught biology and landscaping at a prefectural high school in Saga for 23 years.

However, I realized the importance of food after stress caused me to break down, and in 1991 I started my career in agriculture.

The Chikushi Plain, where the farm is located, is one of the largest granary areas in Japan facing the Ariake Sea.

The reeds that grow in the brackish waters of the Ariake Sea, into which the Chikugo River flows from the Aso Mountains, were once used as fertilizer, fuel, and for reed-thatched roofs.

However, with the advent of pesticides and chemical fertilizers, the reeds have been forgotten.

I decided to try organic, pesticide-free farming using reed compost, hoping to make use of the reeds in agriculture.

In the beginning, I was treated as an eccentric and had some difficulties, but later I succeeded in growing ancient rice.

In 1995, I established "Yoshinou" to sell the crops I produced.

In 2002, I became the first Japanese person to receive the Slow Food Grand Prize from the Slow Food Association in Italy.



Sustainable and unique farming methods

Microorganisms live in the reeds.

Especially in summer, reeds contain a large amount of microorganisms, and when cut and mixed with rice bran and water, they ferment and become good compost.

Crops grown without the use of any pesticides, herbicides, or chemical fertilizers have a much different taste and last much longer.

Ancient rice includes red rice, black rice, and green rice.

These are varieties that have inherited the characteristics of wild species and contain rich minerals and vitamins.

These are blended together with other minor grains and sold as a product called "Kokumotsu Zanmai".

Just by mixing a little of it with white rice, you can enjoy it even more.

Normally, when we take our home-grown soybeans to soy sauce, miso, or tofu manufacturers, they won't buy them because their production lines are designed to meet the standards for imported soybeans, and they have to readjust their soybeans every time they use non-standard domestic soybeans.

So we make our own soy sauce, marinate chopped garlic from Kyushu, and sell it as "229 Soy Sauce," which is slowly aged in a tunnel in Karatsu, Saga Prefecture.

We also produce other products, such as "Ito's Salt," which is made by adding rock salt to salt from Nagasaki's Goto Sea and adjusting the magnesium content to an appropriate level, all of which take into consideration the effects on the body.


For Customers

Interested in the natural environment through food!

Food is the source of life, and agriculture is an important and indispensable industry.

At our company, we provide agricultural students and young people young man confined to his house with the opportunity to experience the actual work of farming.

It is important for us to increase the number of people who want to become farmers and for consumers to become interested in farming.

In 2008, we established the "Association to Protect the Sea of Fertility Genkai and Ariake", and have been working to inform people about the harmful effects of herbicides, which pollute the sea and rivers the most.

We hope that through our food and farming experiences, people will become more interested in agriculture and nature.
