Japan's futuristic airport hotel lets you rent tiny pods for power naps
Nine Hours is a Japanese chain of pod hotels started in 2009, with each chain designed to accommodate people for between one and nine hours depending on their needs.
For $44, guests gain access to a private pod, sleepwear, and access to the bathrooms and lounge. Or for $7 you can just take a shower.
Here's what the express hotel is all about.
