Since the LEGO City series centers on "cities" where everyday heroes thrive, guest Shingo Yanagisawa appeared from inside the truck dressed as a "Police" hero protecting the city's safety. He immediately performed his signature police impersonation. He then proceeded to non-stop impersonate the sounds of various vehicles featured in the diorama: the Shinkansen bullet train, helicopters, and racetracks. Yanagisawa, who shared that he had admired heroes since childhood, introduced the city – the stage for these heroes' exploits – through his impersonations one after another, greatly energizing the venue.
Also appearing at the presentation was the diorama's creator, Junpei Mitsui, one of only 12 LEGO Certified Professional Builders worldwide. He spoke about the creation process of this grand diorama, which took about three months to build, and his passion for LEGO City. He expressed his hope that many people would experience the joy of LEGO bricks through this event.
