Tsutsumi Clinic (Tosu Main Clinic), located in Yayoigaoka, Tosu City, Saga Prefecture, is an internal medicine clinic operated by the medical corporation Tokurinkai. The clinic upholds the philosophy of "warm-hearted medicine from the patient's perspective," and puts into practice the spirit of "Jo" — the concept of treating others as one would wish to be treated — in daily clinical care. With a fundamental policy of providing thorough, high-quality medical care to prevent serious illness before it occurs, the clinic considers all aspects of the patient's surrounding environment in order to deliver the most appropriate treatment. As the main clinic of a medical corporation with multiple locations centered in Kyushu, it is actively involved in community-based activities, including hosting training sessions with local care managers and giving lectures at community welfare council salons, demonstrating a strong commitment to collaboration with regional healthcare and welfare services. Consultations are available weekdays from 9:30 AM to 5:30 PM, with the clinic closed on weekends, public holidays, and the year-end and New Year period. English-language support is available, making the clinic accessible to patients who prefer to communicate in a language other than Japanese, and on-site parking is provided for convenient access by car.
