The £1.37m HRP-4C humanoid has battery-powered motors in her face to help her flash a smile, lower her eyelids and sashay along a catwalk.
Measuring a slightly short 5 ft 2 inches and weighing a model like 43 kg, the features of the robot were modelled on the wide-eyed characters popular in Japanese "anime" cartoons.
However, despite her apparent physical perfections, its creators at National Institute of Advanced Industrial Science and Technology (AIST) admitted it had a long way to go before it would rival real life models.
"Our robot can't move elegantly like the real models that are here today," admitted Shuji Kajita, director of humanoid robot engineering AIST.
"It will take another 20 to 30 years of research to make that happen."
Japan is famous for its cutting-edge robotics industry and is home to nearly half of the world's 800,000 industrial robots, many of which are being developed to assist the nation's rapidly ageing population.
Can a robot really be a runway model? Don't runway models wear the newest, weirdest clothes, show off alot of flesh and swing those hips? Robots can't do that!
