>>1962346Bike registration is mandatory in Japan. Every bike is registered. When a used bike is sold, the buyer and the seller have to go to the local police station together and file a form to notify the government of transfer of ownership. If you ever get stopped by a traffic cop while riding bike, they will randomly check your bike registration to see if you're the owner of the bike (100% chance if filthy gaijin). If you live in an apartment complex, and you show up with a new bike, the security guard will ask to see your bike registration (so that they know which bikes are residents' bikes and which bikes are guests' bikes but really because they're checking if the filthy gaijin has stolen a bike and if so they mark it on your file and try to find a way to evict you before you bring more trouble to the property).
