What is the way to send a letter from a post in the world's "deep" place

In 2002 the Guinness Book of 'Post in the deepest place in the world"Wakayama prefecture in Shuranshimi-cho" was certified as "Sushimi underwater post". As its name suggests, it is located at a depth of 10 meters and it is in a place where it can not be reached at all simply by dive, but the post is functioning and the letter is reaching properly So I actually posted a letter from the post.

So I arrived at JR Shiromimi Station in Wakayama Prefecture. It is a peaceful station by the seaside.


Dive this time in a few minutes by car from the stationClub Noah SusimiArrived at. When you do not know the location, you can also ask for transportation to the station in advance.


This is reception.


First of all, I will apply for an experiential diving.


There are tables in the waiting space ... ....


Drinks and so on were allowed to drink freely.


Tea and coffee are self-service.


Books related to the sea are lining up.


It is good to spend relaxing and relaxing after the time before the experience dive begins or after it ends.


Because you can borrow a diving suits perfect for yourself from height, weight and foot size you entered when you submitted an application form ... ...


I change clothes rooms like a blue prefab cabin.


In the changing room there is a basket for putting luggage ......


shower.


There was a cream for hair dryer and tissue / hair care. Valuable items are deposited at the reception, use towels, shampoo & rinse etc to bring with you.


People who are trying to experience the underwater diving to see the submarine post are elsewhere, everyone enters into the ocean with this kind of suits.


At the reception, a postcard for posting was posted at 170 yen per sheet, so purchase. I got some strips for some reason.


I will write a wish for the time being.


Fill in the postcard.


When you are ready, a lesson dive class begins. In the class, I will learn how to breathe in the sea, how to cope when the goggles cloudy, how to remove the ears, how to show "OK" "trouble", "swim slowly" etc by hand sign.


This is a bottle. Since the equipment is about 20 kg in total, it will feel like you are doing muscle training or practicing as much as walking with your back.


I will head towards the sea while becoming a foot gimmick with a cylinder and weight attached.


Going through the concrete path ... ...


A lush ocean was spreading.


Go down the street made of wood ... ...


It is getting in from here. Since the foothold is bad, "I think I might die by striking my head when I fell down," proceed while throbbing.


A rope is attached to the rock.


As this continues into the sea, you can move to the desired point well by following the rope and proceeding.


So, I got into the water.


As you go along the rope, it gradually becomes deeper, and when you dive to a certain extent the rope is cut off and you can enjoy the undersea world with the help of the instructor.


Because of the high transparency of water, it is possible to see the fish swimming in sway.


Looking closer ......


Sea creatures are lurking in various places.


NyoronyoThere! I heard that it is an egg of AOLIICA.


And ...


There was really a post in the sea. When thinking that something is growing beside ... ...


It was the Tanabata season so it was decorated with bamboo.


I will attach the strips I wrote earlier.


Underwater post where the ancient ruins like dignity will no longer know where the postal mark is, but there was a mailing port properly. I will mail you a letter from here.


Actually, there are two submarine posts, and it is said that they are exchanging every period. In fact there was a post which had already discolored white on the ground due to shellfish.


Atmosphere different from seeing in the sea.


The surface is bumpy.


Looking closely, it was possible to confirm the postmark "〒" under the mailing slot.


The letter that I made was in an atmosphere that seems to have passed through a tough struggle, such as folding or discoloration, but I got it to the editorial department of GIGAZINE properly.
