Founded on the principle of "providing the best and most up-to-date medical care, and contributing to society with warmth and kindness of heart," Mazda Hospital is committed to community contribution by providing healthcare as a core community hospital in eastern Hiroshima City. Though established by a private company, Mazda Hospital is well used by local residents, who now account for 85% of outpatients and 97% of inpatients.

Since 2015, Mazda has cooperated with the Hiroshima Prefecture Nursing Association to conduct on-site classes so that students can learn the importance of life and gain an interest in medical professions through learning about nursing work and the role of disaster relief nurses.
In FY2019, during visits to neighboring junior high schools, students experienced taking pulse measurements and carrying the necessary luggage (about 20 kg) of a disaster relief nurse dispatched to a disaster area. Additionally, speakers conveyed the importance of life and of medical support for disaster-affected areas through sharing experiences of dispatches and nearby disasters, such as the heavy rains in July 2018. Students commented, "I learned that nursing is a job with lots of responsibility," "Life is the most important treasure," and "I realized that I should be thankful for life."
