Japan's Henn-na Hotel — which translates roughly to the 'Strange Hotel' in English — has some pretty unusual employees.

The hotel in Sasebo, Japan, opens on July 17, and will be manned almost entirely by robots. What started as an effort to cut down on labor costs has turned into something of a publicity stunt to create the world's wackiest hotel.

But Hideo Sawada, who runs the hotel as part of an amusement park, insists using robots is not a gimmick, but a serious effort to utilize technology and achieve efficiency.

Upon check-in, guests will be greeted by multi-lingual humanoid and dinosaur receptionists. Other robots in the lobby greet visitors, serve coffee and act as concierge. Robots bring the guests' luggage to their rooms, which, by the way, are opened by face-recognition technology.
