This is Miyamotoyama, a small farm located in the middle of a valley and a rich satoyama forest.


We plant and harvest rice and soybeans, and process fermented foods such as pickled plums, miso and koji.

Fresh eggs are also harvested from small free-range poultry houses for poultry manure.


“I grow rice and soybeans, and even prepare miso! I will do my best to coexist with the rich nature and deliver delicious food to the dining table. The theme is agriculture where the customers who eat the farms and the farms can live in good health. We will continue to pass on satoyama agriculture.”

I am a farmer in the Miyamoto district of Sosa City, Chiba Prefecture.

We are doing circular farming in Miyamoto Ward, Sosa City, which is located in the northeastern part of Chiba Prefecture. Rice (variety: Koshihikari, Himenomochi), local soybeans (variety: Miyamoto native), plums, and a small amount of vegetables are cultivated in fields located in rich Satoyama and Satomori without using pesticides or chemical fertilizers. We have also begun conservation activities for indigenous varieties and fixed species.

The beginning of agriculture that is close to nature without using pesticides.

In 1986, I, Cho, who took over Miyamotoyama's farming business, was born. As a baby, I had severe atopic dermatitis, so at my mother's suggestion, we started completely pesticide-free cultivation. At that time, there was no understanding of pesticide-free farming, and there were conflicts with fellow farmers who lived in the same area. Gradually, the number of friends who agreed with my father's enthusiasm increased, leading to cooperation in stopping the aerial spraying of pesticides by helicopter, which was being carried out at the time. The reason why fireflies still exist in villages in the Miyamoto area is that these local efforts are still alive.

Agriculture is not something we can do alone,
Thanks to the cooperation of the villagers and everyone who supports us, we have been able to continue.

Since 1986, when we were certified as specially cultivated rice, we have been directly connecting with our customers and delivering carefully cultivated rice, eggs, and processed products. Miyamotoyama, who has been a farmer for generations, has been farming in the Miyamoto area for 1,300 years. With the motto of agriculture that can coexist with the satoyama where we live, we grow crops organically without using chemical fertilizers.


Good compost Fermented rice field

Homemade compost made mainly from rice bran and bean curd lees is used as fertilizer for the cultivated fields. Fields that do not require fertilizer use the power of plants (green manure) to enrich the soil.

By having plants in the field all year round, the soil is getting better and better.

healthy soil

In order to create healthy soil, green manure cultivation and rice straw plowing are returned to the soil. A field where microorganisms decompose and ferment a lot of organic matter is completed. Satoyama is home to a rich ecosystem, and in the summer, Genji firefly, Heike firefly, and the endangered species Tokyo salamander inhabit.

In the rice fields where various creatures live, we cut the grass without using herbicides to manage the satoyama.


Farming with tempura oil

We want to take care of the environment, so we use recycled biodiesel from tempura oil used in homes and restaurants as fuel for farm work.

Fuels made from plants are said to be carbon-free or plus or minus zero energy. Furthermore, the edible oil that was disposed of as garbage is used up in food production, so it is a very eco-friendly initiative.

Together with the beautiful Satoyama.

Miyamoto Ward, where Miyamoto Mountain is located, is a satoyama with a rich ecosystem surrounded by small valleys and forests.
Rare creatures such as the Heike firefly and the Tokyo salamander also inhabit here.

We donate part of our rice fields to local private schools and school biotopes.
According to the announcement by the Center for Biodiversity, the population of the endangered species, the Tokyo salamander, is 10 times higher than in the surrounding area. It can be said that this is the best in Japan. It can be said that our agriculture is in harmony with the wonderful satoyama. Heike firefly observation events are held by local residents in the summer.
