Hideo Sakata remembers the time of "lawlessness" when it was easy to find a place in Tokyo's Roppongi district to park his motorcycle.

"Everybody used to park on the sidewalk or on the side of the street and they never got tickets," said Sakata, who has been commuting to Roppongi by motorcycle for 20 years.

Things changed when the Roppongi Hills complex opened in April 2003 and police started cracking down on illegal parking.
