Japan's Henn na Hotel, or "The Strange Hotel", recently celebrated the opening of a second branch nearby the Tokyo Disney Resort in Urayasu, Chiba Prefecture. The name of the hotel is a wordplay in Japanese for both "strange" and "evolving", with both concepts being echoed by the fact that the hotel is staffed by robots and robot dinosaurs.

Travel agency H.I.S. Co. has a vision for the hotel that offers both the excitement of Japan's lauded robotics technology and what hopes to be the most efficient hotel experience in the world. The keyless hotel, which features 140 robots that do everything from carrying your luggage to cleaning your room, also spares no robotic expense in decoration. It even has robotic fish that are insanely lifelike.

This video by The Japan Times shows the robotic fish swimming around in an eerie, but impressively realistic manner.

The realistic robotic fish are not unlike the robot carp shown off at Tokyo Design Week 2016.
