Matsuo Internal Medicine Clinic, located in Kaminakano, Kita-ku, Okayama City, opened in October 2009 and specializes in internal medicine. The clinic operates under the leadership of Director Dr. Keisuke Matsuo and Deputy Director Dr. Naoko Matsuo, offering three departments: general internal medicine, respiratory medicine, and pediatrics. The general internal medicine department takes a comprehensive approach to whole-body care, accommodating patients who are uncertain about the nature of their condition or those managing multiple internal conditions simultaneously. The respiratory medicine department handles a broad range of pulmonary conditions, including lung cancer, pneumonia, asthma, chronic obstructive pulmonary disease (COPD), spontaneous pneumothorax, and pleuritis. The pediatrics department prioritizes direct communication with young patients and follows a policy of minimizing tests and treatments while emphasizing the body's natural healing abilities. In addition to early disease detection, the clinic places emphasis on lifestyle management and guidance, offering a dedicated consultation room where patients can discuss their concerns and symptoms in a thorough and attentive manner. The clinic provides care based on informed consent and also offers second opinion consultations and home medical care support. Weekday and Saturday morning hours are from 8:30 to 11:00, with afternoon hours on Monday, Tuesday, Thursday, and Friday from 15:00 to 17:30. The clinic is closed on Sundays and public holidays. English-language support is available, and the facility is equipped with parking and barrier-free access. The clinic also collaborates with institutions such as Okayama Red Cross Hospital and Okayama University Hospital.
