The integration of autonomous buses (ABs) in Japan offers a solution to the challenges posed by an aging society, promoting safe and convenient transportation for older adults. In Ibaraki, Japan, AB adoption exemplifies forward-thinking infrastructure development, addressing residents’ needs through partnerships and innovation. Positive perceptions, especially among females in their 60s and 70s, highlight ABs’ role in enhancing safety and trust. This study, based on our interviews in Sakai Town, underscores ABs’ significance in meeting practical needs, while fostering social inclusion. Despite challenges like technology and cost, collaborative efforts and policy interventions can maximize ABs’ potential, ensuring equal access to services and paving the way for a sustainable and inclusive transportation future, benefiting both aging populations and communities.
