Guests - or should that be inmates - check into the 'Prison Inside Me' hotel in Hongcheon, 80km north-east of Seoul, not for spa treatments, fine dining or long lie-ins...but to sample what it's like to be banged up.
Founded over a decade ago by former lawyer, Kwon Yong-Seok, and his wife, the hotel's raison d'etre is to let people experience life minus everyday comforts which, they say, allows them to get more in touch with themselves.
When guests, who pay around £100-a-night to check in, arrive they're greeted with the kind of cell that a criminal held at His Majesty's Pleasure might find themselves locked up in.
Banish thoughts of a comfortable bed too, there's a simple mat on the cell's floor, alongside a small desk and a toilet.
Mobile phones are banned, there's no way of telling the time and even basic vanity is off the menu, with no mirrors in the cells.
Dinner - a basic affair - arrives via a hole in the door, just as it would in some of Britain's high security prisons.
