Abstract This study examines how institutional design shapes residential environmental interventions through a comparative analysis of home modification support systems within the long-term care insurance frameworks of Japan and Korea. With aging in place as a central policy objective in aging societies, the analysis focuses on differences in policy goals, support structures, and implementation processes between the two countries. A qualitative comparative methodology was used, based on policy documents, operational manuals, and publicly available guidelines related to long-term care insurance home modification programs. The comparison considers eligibility criteria, support amounts, scopes of modification, and implementation procedures, with particular attention to planning and decision-making processes. Findings indicate that Japan's home modification system, introduced as a statutory benefit in 2000, follows a goal-oriented approach prioritizing functional improvements in daily activities through flexible spatial interventions. Professional involvement at the planning stage, including care managers and housing specialists, enables tailored responses to diverse housing conditions. In contrast, Korea's home modification support, launched as a pilot program in 2023, uses a standardized, item-based framework with limited subsidies, restricting design adaptability and comprehensive spatial improvement. Korea also lacks a formal mechanism for expert-led assessment and planning before construction. The study concludes that effective home modification policies require a shift from item-based provision to goal-oriented spatial planning supported by professional assessment. It contributes to housing and architectural research by clarifying the institutional conditions that shape the quality and scope of residential environmental interventions.
