U Japanu, Hong Kongu i sličnim azijskim zemljama to nije čudno. I dan danas u velikim gradovima ljudi žive u tzv. "coffin hotels" - samo ležaj i priključci za struju, internet i slično. Nama je to neshvadljivo, ali u prenapučenom gradu kao što je Tokyo prostor je dragocijen i jako skup. Zato mnogi žive u "kovčezima" ili ovakvim sobicama.

Since most visitors to a Capsule hotel are Japanese business men WHO DON'T HAVE TIME TO GO HOME, there are amenities there for people who didn't plan on staying away from home.
