The Tokyo Metropolitan Institute of Gerontology focuses on enhancing the quality of life for the elderly by providing appropriate medical care aimed at achieving healthy longevity. The institute promotes a dual physician system, emphasizing the importance of establishing a personal physician, or kakaritsukei, who helps patients monitor their health and manage chronic conditions. This physician not only offers routine consultations but also assists in early disease detection and necessary referrals for specialized tests or treatments.

The hospital is dedicated to acute care, accommodating high-severity patients who require specialized interventions. After acute treatment, patients are encouraged to continue their care with local healthcare providers to ensure ongoing support. The institute also features a referral desk for patients without a personal physician, guiding them to trusted medical facilities in the area.

By fostering cooperation between the center and community healthcare services, the Tokyo Metropolitan Institute of Gerontology plays a pivotal role in supporting the health and well-being of its patients
