If you go to Tokyo, you may want to check into 9h — Nainawasu in Japanese — a luxury capsule hotel that is nine storeys tall, storing 125 capsules that use Panasonic’s environmental and lighting control system.

According to Panasonic, their system controls lighting to guarantee “good sleeping”. I don’t know about you but, to me, “good sleeping” means a large bed, a good doona and someone special to spoon with all night. Still, if you want to get close to the experience of hibernation in a deep space vessel, this is the place to go. [9hours via 9h]
