Capsule Inn Hamamatsucho
Tokyo, Japan
This is the classic Japanese capsule format, without design-hotel styling. Guests sleep in stacked pods on dedicated floors. Each pod has its own light and alarm, and luggage goes to storage or lockers.
The location is the main draw. Daimon subway station is close by, and Hamamatsucho has the monorail to Haneda Airport. That makes it a practical first or last night in Tokyo. Zōjō-ji temple and Tokyo Tower are within walking distance.
Facilities are simple: a front desk, shared washrooms and a bathing area. Which floors are open to which guests is decided by the property, so check its current policy before arriving.
