An Undersea Mailbox

  • Today, I will talk about an undersea postbox in Wakayama Prefecture in Japan.


    As the name implies, this postbox is located under the sea.

    The distance from shore is 100 meters, and the depth is 10 meters, so you have to prepare diving to put a letter in the postbox.

    An average of ten letters per day are dropped, and a diver collects them everyday, then they are delivered throughout Japan.

    In 2002, this postbox was recognized in the Guinness Book of Records for the deepest underwater postbox.

    By the way, since the undersea postbox is deteriorated by shellfish and seaweeds, it is replaced once a year.
