Japan’s capsule hotel concept takes solo accommodations to the next level. With more than 10 locations in Tokyo and others scattered across Japan, the ninehours chain offers travelers the chance to stay in individual sleeping pods. After a busy day exploring Tokyo gems like Odaiba and the Imperial Palace, guests can load their belongings into designated lockers, shower in the bathroom facilities and change into exclusive ninehours loungewear. Bath towels, shampoo, conditioner and toothbrushes are provided, and each sleeping pod measures about 7 feet long by 3 1/2 feet wide. Though the capsules are ideally designed for one-night stays, the accommodations can be reserved for consecutive nights at a discounted rate.
