It addresses a wide range of sleep-related conditions, including insomnia, hypersomnia, and CPAP outpatient care for obstructive sleep apnea, and is distinguished by its delivery of cutting-edge sleep medicine. As part of the Sleep Clinic Group, which operates seven clinics nationwide including locations in Tokyo, Sapporo, and Sendai, it has earned the trust of local patients as a dedicated sleep medicine facility. Clinic Director Dr. Takuro Endo is a widely recognized sleep specialist, known for his publications and television appearances, and his high level of expertise—built on research inherited from his grandfather—underpins the clinic's practice. For first visits, the clinic follows a thorough process: after an initial consultation and examination, patients are lent a simplified testing device for home use, and at the follow-up visit, test results are analyzed and the treatment plan is explained in detail. Hours extend to 7:30 PM on weekdays and Saturdays, making it convenient for after-work visits. The clinic accepts credit cards and electronic payments, and is equipped with parking and barrier-free facilities, creating an accessible environment for a diverse range of patients.
