Coming from a city where bike theft is severe, the biggest culture shock for me in Japan was seeing how they "lock" their bicycles: loop a flimsy metal ring through the back wheel, and walk away. You could easily still wheel the bike away on its front wheel or toss it into the back of a truck. And yet, it will always still be there when you come back. Amazing.

If they use any lock at all. Even in the heart of tokyo you'll see bikes just propped up against a wall or sitting in a rack with no lock at all.

My house and workshop in rural Canada were like that: no locks. Nothing. Massive quantity of expensive tools in a completely unsecured building.

This made for a bit of a tricky scene during title transfer, how do you pass the keys to the new owners if there are no keys...
