Q: What is a capsule hotel? A: A capsule hotel is popular among businessmen in Japan. Often times they work late and miss the last train home; therefore, needing a quick, quiet, inexpensive hotel with all the necessities. Enter capsule hotel. You literally sleep in a "capsule." The one I stayed in was two levels high (luckily I was on the bottom), but I think some go three high. It was hard finding a capsule hotel to stay in because most are just for men. However, in Osaka I found one with a women's dormitory as well.Everyone is given a key to enter their area: men or women's. In your area there is a locker room, public bath spa, laundry facilities, and the dormitory rooms of capsules.
They give you pajamas and you can even buy business-type clothing for men upstairs. Everything you need...
Here are some pictures of inside the capsule.
