In considering the 15-minute city model, the concept of proximity plays a central role. Therefore, the primary benefit of urban planning models focusing on proximity is the possibility of designing compact and interconnected urban grids that ensure easy access to the vital services and infrastructure. Considering the need for the affordable and accessible urban layout for the elderly, these urban planning principles are especially valuable. The reason is that the elderly may not be able to use fast and convenient means of transport and, therefore, require the development of a physical layout that is easily accessible. The importance of this benefit is also explained by the drawbacks of conventional urban planning models, specifically, the negative physical separation of the residential areas from the places where people access daily needs, leading to transportation dependence and social isolation of the elderly. In turn, a 15-minute city combines a walkable, cyclable, and universally accessible physical layout that ensures that the daily needs of all categories of people―including the elderly―are met.
This study examines the implementation of the 15-minute city concept in Kitakyushu, Japan, to address the needs of its aging population, focusing on accessibility, mobility, and digital integration. By analyzing how proximity to essential services
