Located on the 3rd floor of Makita Building, a 4-minute walk from Exit C9 of Ikebukuro Station and 5 minutes from the West Exit, Sleep Primary Care Clinic Ikebukuro specializes in sleep and sleep-related disorders. The clinic addresses insomnia, difficulty waking, middle-of-the-night awakenings, restless legs syndrome, and persistent sleepiness regardless of hours slept, conducting detailed analysis of individual sleep patterns and issues to identify underlying causes. Beyond insomnia treatment, the clinic accepts patient transfers for narcolepsy and idiopathic hypersomnia, providing care based on the International Classification of Sleep Disorders covering over 60 conditions. They also treat circadian rhythm sleep-wake disorders, including delayed sleep-wake phase syndrome where patients struggle to wake up for school or work due to circadian disruptions and cannot fall asleep early in the evening, as well as non-24-hour sleep-wake rhythm disorder where sleep and activity periods continue shifting daily. Clinic hours are divided into two sessions from 13:00-17:00 and 18:00-22:00, Monday through Sunday, closed on public holidays, January 1-3, and December 30-31. English language services are available.
