> In Japan, citizens are required to take lost property to the Koban (police station). From there, it is either returned or stored at the Tokyo hub until claimed.
A few years ago, I found a wallet on the ground and I took it to the police station. (The experience itself was a bit bizarre, they evidently had a "triage" system where you have to use a computer to select why you're there and get a ticket number, then sit in a waiting room until you're called - mostly with people picking up their kids from the drunk tank - this was a sunday morning).
Anyway, the police officer that eventually received me told me that they don't accept lost wallets, and that basically I was on my own if I wanted to figure out how to return it. (There was stuff with the person's name but no address in the wallet).
