Located in Kanagawa Ward, Yokohama, Kanagawa Prefecture, this internal medicine clinic offers English-speaking services and barrier-free facilities. The clinic specializes in the treatment of sleep apnea syndrome, with medical care provided by a Doctor of Medicine and a Sleep Society-certified physician. For individuals experiencing symptoms such as daytime sleepiness, lack of deep sleep, headaches upon waking, frequent nighttime urination, and snoring described as breathing stopping during sleep, the clinic conducts diagnosis and treatment through questionnaire-based self-checks and CPAP therapy. Sleep apnea syndrome not only increases the risk of developing lifestyle-related diseases such as hypertension, heart disease, stroke, and diabetes, but is also linked to traffic accidents and occupational accidents due to daytime sleepiness, making it important to control symptoms through appropriate treatment. At this clinic, symptoms are confirmed through questionnaires, and specialized examinations and treatments can be received as necessary.
