All these bicycles are illegally parked!
After a while, these bikes will be removed and the owner will have a letter sent to them asking them to pay a fine of about
3000 yen-ish. The authorities have your address because most people register their bikes in the event that they ever get stolen.
If one decides not to pick up their bike, the authorities would either recycle and sell or dispose of it.
Do you have to pay a hefty fine in your kingdom when your bike is impounded?
