This is interesting dear Steemits!!
When the small Japanese seaside town of Susami needed a tourism boost, an unlikely resident came to the rescue: the town’s postmaster.
Together with the local diving community, former postmaster Toshihiko Matsumoto helped establish the world’s first underwater.
Those willing to make the plunge can strap on a wetsuit and mail letters from 30 feet under the sea. Incredibly, dive shop owner Hiroaki Yamatani descends each day to collect and deliver these letters to the post office. To date, almost 38,000 letters have been sent from under the sea.
Where is it located?
The world’s deepest underwater Postbox is located in Susami Bay in Japan, and is said to lie at a depth of 10 meters underwater. People usually travel from different cities to mail their letters to their family members located in other different cities.
This postbox mainly lures those people who purchase the water-proof cards on which the message is written with the help of the oil-based paint markers, because of which the message can remain intact on the card despite the underwater immersion.
People then dive into the sea to post their mail, and it is said to be a thrilling experience for many people who engage in this activity.
The underwater postbox actually came into being during a fair in the year 1999, as part of an effort to give special attention to Susami Bay.
This is truly a success story.
