So, I had a friend fly into Japan a few months back (before the earthquake if that matters).

He flew in from Canada and his final destination was Singapore.

He had an overnight layovver at Japan. So, his plan was to just hang out at Narita. Now, what happened was that the Narita officials told him that he cant just sit around. He NEEDS to have a hotel.

He didnt want to spend any money and resisted, but they put their foot down and said, "Either pay or be deported back to Canada".

Obviously he ended up forking out the cash.

Whats up with this rule?
