Underwater Post Box (海中ポスト)
The Underwater Post Box is about a 19-minute walk from Susami Station on the JR Kisei Line, in water about 10 meters deep 100 meters off the Karekinada Coast in the town of Susami. It was set up in 1999 on the occasion of the Nanki Kumano Taikenhaku, an outdoor exhibition, and it has been listed in The Guinness Book of World Records as the world's deepest underwater post box. Visitors can buy special waterproof artificial paper for use in the underwater post box at Club Noah Susami. They do not even have to dive down to the bottom of the sea to mail their postcards; staff members will do it for them.
