Japan Bike Parking Laws

It was interesting to see that in Tokyo where there are millions of cyclist
getting around, and with great respect from cars and pedestrians unlike
Australia that seems to hate Cyclists guts.
Anyway an interesting thing I saw was that many bikes were getting parking
tickets for parking in an illegal area, and what I made out was that you get
some sort of warning for a few hours, and after that a huge truck comes
along and gets your bike and impounds it, and I saw the impoundment yard
full of bikes, and a sign saying the penalty is a 6,000 yen or about $60 to
get your bike back.
Amazing.
Also its amazing that you can leave your bike outside your apartment
overnight unlocked and still find it there in the morning, again unlike
Australia.
