Tokyo Dome Exit

So... did you know that Tokyo Dome has an inflatable roof? All entrance to the Dome is by rotating doors, which keep the high pressure (needed to keep the roof up) in. When the crowd is exiting, they open some regular doors too, but employ 'catchers' outside to make sure people get out safely! :D
