Value-added rice products associated with ecological protection have attracted significant research attention in recent times. However, farming methods related to the production of these products are not diffusing rapidly. This study analyzes the factors affecting the diffusion of conservation-oriented farming methods, or, in other words, the farming formula to nurture oriental stork and Japanese crested ibis. We focused on three parameters that impact the shape of diffusion curves—time required to reach an acceptance of 5%; rate of acceptance; and ceiling value. The case study showed that the diffusion curve of each farming method had a different shape. Rapid diffusion of the formula at an early stage can be ensured by conducting seminars on new farming technologies. In addition, the ceiling value can be increased by purchasing rice at higher prices, promoting awareness of the factors that prevent farmers from introducing these methods, and regularly conducting seminars for farmers.
