In 2018, “Garden Residential Zone”, the thirteenth land use zone was added to the Japanese City Planning Act to protect the environment of low-rise residential buildings while promoting the use of urban farmlands. This study aims to propose four scenarios for the model farmers in Takamatsu District, Nerima-Ku, Tokyo that allow them to continue their agri-activities under the new land use zone. After comparing the regulations and the incentives of the new zone and the currently designated zone, the four model farmers were selected to ensure the diversity of the scenarios. By the zoning change to the “Garden Residential Zone”, it is possible to reduce the tax burdens of small-sized farmers who are not supported by the traditional system around “Productive Green Districts”. In order to apply these scenarios, it is important for the entire district to have a mechanism to utilize agri-assets and an organization to manage it.
