Located just a 4-minute walk from Subway Shin-Yokohama Station Exit 7 and a 7-minute walk from JR Shin-Yokohama Station North Gate, this clinic is conveniently situated near the stations and offers consultations on weekends. Certified as a "Specialized Medical Institution Type A" by the Japan Society of Sleep Research, it provides diagnosis and treatment for a wide range of sleep-related disorders including sleep apnea syndrome, hypersomnia, narcolepsy, restless legs syndrome, and REM sleep behavior disorder. Beyond its high level of specialization, the clinic has established a coordinated system where doctors and laboratory technicians work together to provide consistent care from examination through treatment. In addition to inpatient overnight polysomnography and daytime sleep testing, the clinic offers home PSG testing, with careful support provided from pre-examination explanations through post-examination follow-ups. Since the Shin-Yokohama branch opened approximately 12 years ago, PSG tests have been performed on over 5,000 patients, and approximately 3,800 patients are receiving CPAP treatment across both branches. The clinic uses an appointment system to reduce waiting times and offers convenient facilities including English-language support, acceptance of credit cards, debit cards, and electronic payments, parking availability, and barrier-free access.
