Japan plans 200km bridge, undersea tunnel link to South Korea
AN ambitious plan to link Japan to South Korea through a 200km series of bridges and undersea tunnels will be launched soon by high-powered Japanese politicians.
Their main proposal calls for a road and rail link starting at Karatsu on Japan's Kyushu Island and finishing at Pusan, which is South Korea's second largest city.
If built, the project's main tunnels would be the world's longest.
There are three options and the one most favoured would include a bridge from Karatsu to Iki Island, a 60km undersea tunnel to Tsushima Island, and then a 68km tunnel to Pusan.
Both tunnels would smash the world record currently held by the 53.9km-long undersea link between Japan's main island Honshu and Hokkaido Island.
By comparison, the Channel Tunnel between Britain and France is about 50km long.
The two other options would route the final section from Tsushima to Geo Jedo Island and then to Masan in South Korea.

At this stage, two types of tunnel are being considered. One calls for three shafts as is the case in the Channel Tunnel. The other would have one large shaft to accommodate road and rail traffic.
The estimated construction cost will be between ¥10 trillion and ¥15 trillion ($111 billion to $157 billion).
A group of nine lawmakers from both ruling and opposition parties last month met to discuss the launch of a new MPs' panel to promote the undersea tunnel project.
The group is led by Seishiro Eto, former director-general of the Defence Agency. It also includes Takenori Kanzaki, former head of the ruling Komeito Party, and Yukio Hatoyama, current secretary-general of the Democratic Party of Japan.
An official from the Japan-Korea Tunnel Research Institute said this week all three routes had merits and no decision had been made on which one would be selected.
But he said the Pusan option had an advantage because it went straight to Pusan through the shortest tunnel of the three. This shaft would be 100m under the seabed, which was 220m beneath the surface. The official said it would take 10 years to complete.
The idea of building a tunnel from Japan to Korea was first suggested in 1917 by Kuniaki Koiso, a former prime minister. A group of Japan's Liberal Democratic Party lawmakers met in May 1983 to establish the research institute.
Three former South Korean presidents, Roh Tae-woo, Kim Dae-jung and Roh Moo-hyun, openly support the building of an undersea tunnel.
When he attended Mr Roh's inauguration in February 2003, then Japanese prime minister Junichiro Koizumi said: "After the settlement of North Korean problem, it (the tunnel project) is likely to be promoted by the business circles (of both countries)."
