Japan feels very safe. There are many “police boxes” on neighbourhood street corners. Very few people own guns. Ladies can walk the streets of Tokyo alone at night.
… I found a briefcase sitting on the street. Looked like the owner had driven away without it.
His name — Osamu Sumi.
Rather than try to explain to the cops why I had this “missing property”, I took it to our hosts at the World Gymnastics Championships. They called the much relieved owner.
Check this two story bicycle storage area at a Tokyo apartment building. Very few of these bike are locked.

I have tons more stories like this from my year there. It was amazing to us to have wallets & train passes returned, find laundry folded and waiting after forgetting it at the laundr-o-mat and to be able to walk down the street alone at 4 am & know you are safe. That said, my locked up & very cool bike, was stolen in Osaka!!! Probably a nasty gaigin!!
