The 9 Hours is a capsule hotel: a Japanese hotel concept with sleeping pods instead of rooms, and shared bathrooms. They target hard-working business people and travelers.
Usually, these capsule hotels are far from well-designed. The 9 Hours is nothing like that. Instead, it's an amazing example of applied minimalism.
Monocle recently did an excellent report on the hotel, which we have embedded here. (Thx, Peter!)
