there are many differences, and similarities between/with japanese and australian bicyle laws, culture and habits.
one such difference is in how most japanese bicycle owners don't tend to lock their bicycle to an immovable object. instead, one or two locks are used to immobilise the wheels. i could only guess that it might be reflective of a generally law abiding culture with low chance of bicycles being stolen, and/or that bicycles are so common and such an everyday part of life, that people might think, "why on earth would you want to steal a bicycle?"
