The capsule format has widened considerably since its first generation. The three Tokyo properties listed here sit at different points along that widening: one built around a bathhouse, one built around an airport terminal, one built around a busy city district. Each treats the berth as the private space and everything else as shared, which is the format's defining trade.
Tokyo, Japan
Centurion Cabin & Spa Ueno-Okachimachi
This property pairs cabin-style berths with a full bathing floor, which is the part most guests come for. The baths are the anchor of the building and the sleeping cabins are arranged around that fact, so the rhythm of a stay tends to run bath first, sleep second.
Cabins are enclosed and lockable rather than open-fronted, a step up from the earliest capsule generation, with a bed, a light, power and somewhere to put a phone. Luggage goes to lockers; the cabin is for sleeping and nothing else, which is the trade the format asks you to make.
Ueno-Okachimachi is a working district of markets and train lines, well connected and cheaper than the city's better-known neighbourhoods, and the hotel is priced and positioned accordingly.

First Cabin Haneda Airport
First Cabin's format borrows from aircraft cabin classes, with berths sold at two sizes and a shared bathing area attached. At Haneda the concept is doing exactly the job it was designed for: the property sits inside the airport complex, which makes it a genuinely practical answer to a late arrival or an early departure.
Cabins are taller and wider than a classic capsule, closed with a screen rather than a door, and arranged along quiet corridors. The larger grade adds standing room and a desk-height surface. Shared bathrooms and a bathing area sit on the same floor.
Nobody stays here for the setting. It exists so that a five-hour gap between flights can be spent lying down, and it handles that narrow brief better than most alternatives.
Tokyo, Japan
Hotel MyCUBE Shibuya
MyCUBE was built for Shibuya, which is to say it is designed around people arriving late and leaving early. Berths are stacked in two levels along shared corridors, finished in plain wood and neutral fabric, and each has its own light, outlet and storage recess.
The communal areas carry the personality: a lounge and pantry space where guests actually sit, rather than the token corridor-with-a-vending-machine that some capsule properties settle for. Bathrooms and showers are shared and kept to a tight schedule of cleaning.
Being a short walk from one of the busiest stations in the world is the point. So is the noise discipline inside, which is enforced in the way capsule accommodation only works when it is.
