Hey guy's
Actually a lot of the japanese locks are standard 5 pin tumbler, and yes Raimundo Japan is still very much on the honour system. Some people have these little built in locks on their back brake calipers, but on the whole, they don't seem to be as security conscious as we in North America. Really wonderful and honest people, very little theft. Most of the neat locks I have seen are like abloy knock offs, and simple locks, these are primarily padlocks in Taiwan.
