Tessei Clinic, located in the mountainous area of Niimi City, Okayama Prefecture, is an internal medicine clinic established in 2013 within the complex facility "Kirameki Hiroba Tessei." It was founded to secure medical access in what was once a medically underserved area, and provides community-rooted healthcare services based on the philosophy that "medicine is a humanitarian art." A defining feature of this clinic is its strong commitment to delivering urban-quality medical care even in remote areas, reflected in the introduction of medical equipment capable of early cancer detection. The clinic conducts general internal medicine outpatient consultations in the morning, while afternoons are devoted to examinations and home visits, with active efforts toward collaboration between home medical care and welfare services. Furthermore, the clinic promotes comprehensive community care by cooperating with diverse sectors beyond health, medicine, and welfare—including administration, education, culture, and industry—and actively engages in community health consultation activities. English-speaking services are available, and the facility offers ample parking, making it convenient for patients arriving by car. Consultation hours are from 9:00 AM to 12:00 PM and 2:00 PM to 5:00 PM, with closures on Saturdays, Sundays, public holidays, and during the year-end/New Year and Obon periods. More than just a medical provider, this clinic continues to deliver attentive healthcare services to local residents as a contributor to community development.
