The Korea-Japan Undersea Tunnel is a projected project to connect the two countries via crossing the Korean Strait using the strait islands of Iki and Tsushima, a straight line distance of approximately 128km at its shortest.
The Channel Tunnel that connects Kent in the United Kingdom and Calais in France at the Strait of Dover is 50kilometer.
The proposals would join western South Korea with Kyushu, southern Japan, and a second route with China’s Shandong Province.
It marks the culmination of decades of discussion and speculation dating back almost 100 years.
The tunnel from Korea to Kyushu would stretch 80 miles under the sea and connect the island place of Japan directly to mainland Asia, transforming trade routes, commerce and tourism.
The project, which would cost an estimated £51.2 billion, aims to create a transportation network between thcountriesns which will be fully opened should North and South Korea will become unified in the future.
