Man reenters Japan after bypassing security

From the Japan Times:

... he got off the bridge by going through an unlocked door and down a stairway. He entered a restricted area on the ground but was not spotted by a security guard who was positioned just below the bridge, the sources said. The man walked through the restricted area for more than 500 meters and left the airport through a gate shortly before 10 a.m. without being stopped by any guard.

I wouldn't suggest this as a way to avoid getting fingerprinted when reentering Japan. It does, however, call into question the whole point of the activity.
