We visited three educational farms in France and collected information in order to investigate an effective method for dietary education in Japan. The French government has set up a special collaborative committee for agricultural education, and there is also an emphasis on sustainable agriculture. This suggests that France has been promoting agricultural education from various perspectives with long-term goals. Numerical comparisons between France and Japan revealed that educational farms are more abundant, and are visited with more frequency in France. All three farms we visited had many instructional panels on display to help promote self-learning, and to educate visitors on the concerns of agriculture in France. The educational farms have many activities available, and they have different goals and contents depending on the visitors' developmental stages. The educational farm has much potential to provide effective dietary education in various ways for visitors of all ages. In Japan, more schools should make use of educational farms. We also suggest that it is important to foster motivated young dairy farmers, as well as developing effective training and financial support for the educational farms in Japan.
