Discussions for a Korea-Japan undersea tunnel have been gaining momentum among researchers, politicians and entrepreneurs, but the project faces many hurdles before it can become a reality.
If realized, the two countries would be linked by a 200-kilometer undersea tunnel from Busan to the Japanese Island of Kyushu.
A high-speed rail would connect the two countries in 50 minutes. The Korea Japan Tunnel Project Association in Busan and the Japan-Korea Tunnel Research Institute, a non-profit foundation in Tokyo, have been leading the research.
Studies on the tunnel has been initiated mostly by the private sector, but government support is likely to gain pace, particularly in light of the role it is expected to play in accelerating travel and business exchanges.
