Guides and field notes on sleeping in a box, well.
Definitions, etiquette, and what thousands of real guest reviews actually say about the capsule format — written by the same editors who score every hotel in the directory.
What is a capsule hotel?
A working definition of the format Osaka invented in 1979 — what a pod actually is, what it costs, who it suits, and how it differs from a hostel dorm with curtains.
Are capsule hotels safe for solo female travellers?
What the review evidence says about safety, women-only floors, and which properties are entirely female-only — with live counts from our directory.
Capsule hotel etiquette: the unwritten rules
The format works because everyone follows the same quiet contract. The rules nobody hands you at check-in — shoes, phones, alarms, plastic bags, and the 10 a.m. lockout.
Enclosed pod, curtained bunk or cabin — which capsule type suits you
Not all capsules are capsules. The three pod types we label on every listing, what each does to noise and privacy, and how to pick before you book.
