Besides visiting trade shows , visiting Japan is also worthwhile to keep up with developments in robotics. Not fond of flying or short on budget? The internet helps!
Here is a nice filmpje by Motherboard with a travel report from Japan. The makers searched for ‘Robot hotels’ and also spoke to people actually spending the night there.

By far the most interesting I found the reactions of the actual users at the end of the movie. I believe these reactions show that the Japanese are not that different from other people when it comes to robots. These reactions could easily have come from a group of Dutch people.
