Japanese Underwater Post-Box

In Japan, just off the coast of a small town in Wakayama prefecture, there is an underwater post-box, which is an actual collection point within Susami’s postal system. The mail is collected from the box every day, by a deep sea diving postman.


When I first heard of this, I thought two things...

1. Wouldn't the letters get wet?
2. Who would actually use it?

Well, the answers to them questions are rather simple... the mail gets put into a waterproof bag/container, and deep sea divers would use them!

It is surprisingly more popular than I originally thought it would be, at the busy times it actually has as many as 200 pieces of mail! There's also a special stamp which is stamped on the mail - obviously - because a normally one wouldn't be waterproof!
