The “readers paradise” has a growing collection of both English and Japanese books, but those behind Book and Bed are upfront about the fact it's not somewhere you're going to find a chocolate on your pillow each evening.

According to the website, bookandbedtokyo.com, “The perfect setting for a good night's sleep is something you will not find here. There are no comfortable mattresses, fluffy pillows nor lightweight and warm down duvets.

“What we do offer is an experience while reading a book (or comic book). An experience shared by everyone at least once: the blissful ‘instant of falling asleep’. It is already 2am, but you think just a little more... with heavy drooping eyelids you continue reading only to realise you have fallen asleep.”
