Ways not to lock your bike

......As said before, petty theft / crime simply doesn't happen because it would bring shame on themselves and their family if they were caught and also the Japanese police are not to be messed with.

The "honour" system in Japan is something to behold. I lived there for 8 months and just couldn't get my head round it.
