Mailbox under Japan
In Japan, just off the small town in Wakayama province, there is a box behind the underwater, is a real collection point in the postal system of Susami.
Letters are collected from the mailbox every day, by a deep sea diving person.

Well, the answer to them questions quite simple ... Letters are put into a waterproof bag / container, and deep sea divers will use them!
It's more amazing than surprisingly than I think it will be, at busy times, it really has up to 200 mail!
