The Mirror Labyrinth is an attraction in an unnamed park in the Tokyo Metropolitian Area. It is the place where the Murder in Mirror Labyrinth case occurs.
As it's name imply, it is a standard maze which walls are made of mirrors and the guests have to locate the exit. Clerks at the entrance and exit keep track of the numbers of visitors to prevent it from being overcrowded and keep the number of guests inside to a maximum of six at once.
During his visit, Kindaichi notices that, while confusing, the maze is actually badly made with the walls not fully reaching the ceiling and allowing people to see through the gaps. Furthermore, a part of the maze is "useless" as the exit door is visible before the bifurcation to access it.
