ABSTRACT As Japan's condominium stock ages, many buildings face both physical deterioration and resident aging, creating governance, financial, and community challenges. This study investigates how incorporated condominium management associations sustain effective management in well‐maintained aging condominiums. Building on a prior questionnaire survey of 82 incorporated associations in the Kinki region, we selected seven associations classified as maintaining relatively favorable conditions despite advanced building age and conducted in‐depth interviews. Three common management features were identified. First, associations addressed resident aging through barrier‐free improvements enabled by incorporation, systematic collection of resident information for emergency response, promotion of community interaction, and efforts to attract new residents. Second, resident‐led self‐management, often supported by expert residents or external professionals, enabled effective use of management fees and the installation of shared facilities such as meeting rooms and parking structures. Third, sustainable governance was achieved through rotation‐based officer selection combined with long‐term support from expert committees, facilitating knowledge transfer and broad participation of unit owners. These practices strengthened ownership awareness and created resilient organizational structures capable of adapting to aging‐related challenges beyond reliance on full outsourcing to management companies.
