3. Henn na Hotel, Tokyo Bay
For the ultimate futuristic Japanese hotel experience, you need to head to Henn na Hotel, which is part-run by robots. Robotic multilingual dinosaurs man the check-in desk, an automatic trolley delivers your luggage to your room, and each room comes complete with its own robot, Churi, who will help you with whatever you need. Things don’t always run smoothly and you may find yourself calling on one of the hotel’s human staff for help, but the concept is a fun novelty. The hotel is next to the theme park Huis Ten Bosch near Nagasaki, so it’s a fun place to combine with your visit there.
