Habitation Hakata 3 is an aged care center that plays a significant role in addressing the challenges of an aging and depopulating urban neighborhood in Japan. This center is particularly relevant in the context of suburban areas built during the 1970s, which are in need of regeneration and services to support the well-being of their older residents.

The "Nagayama model" of community-based integrated care system, which emphasizes multi-stakeholders' efforts in serving older residents, is widely recognized as a successful ground-up model for community care in Japan.This model suggests that the extent to which it can be adopted depends on local conditions and existing capabilities in mobilizing active citizen participation to meet the care and daily needs of older residents.

Habitation Hakata 3, by adopting such a model, contributes to creating an age-friendly environment that promotes aging in place. The center focuses on involving stakeholders from local government, non-profit and business sectors to show concerted efforts in the care and support of older residents. This approach contributes towards a conducive environment for individuals to age safely and meaningfully within the community.
