The dream of a rice field nurtured by black vinegar -- Noda's safe rice and recycling farming methods (2009-)

The cultivation of "black vinegar rice" being promoted in Noda City, Chiba Prefecture, is attracting attention as an example of environmentally friendly farming practices that do not rely on agricultural chemicals or chemical fertilizers. This trial began in 2009, and the rice is grown using a unique method in which brown rice is sprayed with black vinegar in the paddies. Black vinegar is rich in acetic acid and amino acids, which are believed to activate the rice's metabolism and increase its resistance to pests and diseases. Acetic acid, in particular, has a bactericidal effect, aiding the healthy growth of the rice plants and greatly reducing the use of pesticides. The rice produced by this cultivation method has been certified as "Chiba Eco Agricultural Products" and is used in school lunches at elementary and junior high schools in the city.

Black vinegar rice production is spreading throughout the region, and in 2020, 512 hectares, or about half of the city's rice paddies, were under cultivation. Kurozu rice is also known for its taste, with a rich consistency and aroma, and is popular not only for home use but also as a gift. Locally, it is sold at "Yumeaguri Noda" and other direct sales outlets, and has also been well received as a tax return gift. Processed products such as rice porridge and rice crackers have also appeared, increasing the opportunities for them to reach consumers.

One of the farmers actually responsible for the production of black vinegar rice is Ryoichi Senou, who runs Senou Farm in Funagata, Noda City. He grows black vinegar rice on 10 hectares out of his 18 hectares. He does not use pesticides from the seed stage and spares no pains in his cultivation, including sterilization with hot water. This meticulous approach has resulted in both high quality and safety.

Noda City's black vinegar rice is more than just pesticide-free rice; it is also functioning as the core of a regional brand. It is a role model for the future of agriculture, creating a trinity of value: sustainable agriculture with a low environmental impact, revitalization of the local economy, and the provision of safe and secure food.
