Agrarian thoughts are a type of social thought, but their characteristics are not sufficiently clear. One reason is that some thoughts that share the same keywords are given different names. This might show that the originalities of these thoughts are not based on their ideal novelty but on how to combine contemporary issues with agrarian affairs. To consider this point, this paper focuses on two concepts based on less (no) chemical methods: Y. Une’s method for reducing chemicals; and general organic agriculture. These ideas have been developed with a similar viewpoint with regard to social change, but they were not integrated. Therefore, they should not be understood as having a linear relationship simply because both involve reducing the volume of chemicals. A hypothesis in this paper is that they have different images of social change as goals. To compare them, a tetrahedron model was adopted that has four vertices, each assigned to one element. The four vertices represent human, technology, social system, and nature. Une is a thinker who produced a method of growing rice while reducing pesticides and has developed this process as a social thought. Finally, he reached the ideas of agrarianism, integrating over 40 years of considerations. His goal was to establish a new agrarian norm against modernity. This distinguishes Une’s thoughts from general organic agriculture, which prioritizes social extensions.
