Located in Brillia Mare Ariake, Ariake, Koto Ward, Tokyo, Ariake Kazemachi Naika Clinic is an internal medicine specialty clinic that opened in 2021. Based on the concept of "a place where you can rest your body when you're not feeling well, just as a sailing ship waits for favorable winds in a harbor to avoid a storm," the clinic provides personalized care for each patient. Dr. Kenichiro Tanaka, the clinic director, graduated from Waseda University and went on to Saitama Medical University, accumulating extensive experience as an internal medicine and diabetes specialist at institutions including Yokohama City University Hospital and Kanto Central Hospital. He belongs to multiple academic societies including the Japan Diabetes Society, Japan Endocrine Society, and Japan Sleep Society, ensuring highly specialized medical care. In addition to general internal medicine, the clinic focuses on lifestyle-related diseases, particularly diabetes, thyroid disorders, and sleep apnea syndrome (SAS), offering comprehensive treatment approaches including HbA1c management, dietary and exercise guidance, sleep counseling, and CPAP therapy. The clinic also provides pediatric examinations and online consultations, with barrier-free facilities available. Consultation hours are set for weekdays and Saturdays, with Wednesdays designated for home visits.
