Sleep Clinic Chofu

Sleep Clinic Chofu is one of the few clinics in the Tokyo area that focuses almost entirely on sleep disorders — we’re talking insomnia, sleep apnea, narcolepsy, circadian rhythm problems. It’s in Chofu City, out in western Tokyo, so this isn’t a drop-in option if you’re based in central Tokyo. You’re making a deliberate trip.

The clinic has a website with some English content, which suggests awareness of international patients — but don’t assume that translates to a fully bilingual reception desk. Walk in expecting Japanese-first service. A translation app or written notes in Japanese will help. That said, sleep medicine is a specialty where diagnosis often leans on test results and questionnaires, which can make communication slightly more manageable than, say, emergency care.

If you’ve been struggling to get proper sleep disorder treatment at a general clinic, this is the kind of focused specialist that can actually run the right diagnostics. Just come prepared, and don’t expect hand-holding in English.
