The "Japan-Korea Undersea Tunnel" connecting Kyushu and the Korean Peninsula has been proposed since the annexation of Japan and Korea in XNUMX, but it has not been realized even after a century.It has become a phantom plan, but when the South Korean conservative opposition considers construction before the by-election of the mayor in April, it has become a fire.While the relationship between Japan and South Korea has deteriorated, the administration is negative, but is it a complete picture? (Soul, Minoru Aisaka)
"We will actively consider the Korea-Japan Undersea Tunnel. We can expect an economic effect of XNUMX trillion won (about XNUMX trillion yen) and induce employment of XNUMX people."In early February, South Korea's largest opposition "People Power Party" chief executive visited Busan ahead of the mayor's election, and mentioned the tunnel concept along with a new airport construction plan in the suburbs, causing new controversy. That's right.
A spokesman for the ruling Democratic Party of Korea said, "The Korea-Japan tunnel is a" pro-Japanese "agenda that will make Japan more profitable. Is irresponsible. "The party's chairman of the policy committee also ironically said, "The only benefit we can get from a tunnel is to drive to Japan."
Researchers in Japan and South Korea, who have been promoting undersea tunnels for many years, look at these exchanges between the ruling and opposition parties with mixed eyes.
"The tunnel should be promoted as a long-term project between nations. It is not desirable for the ruling party to call the opposition pro-Japan and attack it," said the former president of Busan University of Foreign Studies in South Korea.Professor Emeritus Shinichiro Nagano of Daito Bunka University also insisted, "This is a project that should be carried out by national policy. If you are serious, you should make a presidential election pledge instead of a by-election of the mayor."He explained the background of the concept, the route plan (see CG), and the issues.
Mr. Nagano's optimal route is Plan A, which runs from Karatsu City in Saga Prefecture, through Iki in the remote islands of Nagasaki Prefecture, Tsushima, and Geojedo Island in South Korea to Busan.The total length is about XNUMX km, and it is estimated that the seabed is XNUMX km because it travels on land on Iki Island and Tsushima.There is also a B plan that goes straight to Busan without going through Geoje.Both are much longer than the Channel Tunnel (XNUMX km, XNUMX km under the sea), which opened in XNUMX.The maximum water depth is around XNUMX meters, and the ground is soft, so difficult construction is inevitable.
The total construction cost is expected to be about XNUMX trillion won.The Japanese side will bear the cost from Karatsu to Tsushima, the boundary between Tsushima and Geoje Island will be split in half, and the Korean side will bear the cost from the island to Busan. Draw a plan to spend public expenses.
Both Japan and South Korea have a declining birthrate, and no dramatic economic revival can be expected.Conflicts over historical awareness have deepened, and some have negatively said that tunnels pose a security risk.Without a definite spillover, both people would not be convinced.
Nagano et al. Claim that if a bullet train with a speed of XNUMX km / h enters the tunnel, Fukuoka and Busan will be connected in about XNUMX hour and XNUMX minutes, and Osaka and Seoul will be connected in about XNUMX and a half hours.
Mr. Xu said, "Japan will be a route that connects not only South Korea but also North Korea, Russia, and Europe by land. In the past, Britain and France did not have good public sentiment, but they built a cooperative relationship through tunnel connection. It should be a passage for peaceful dialogue with North Korea and other countries in the process of enhancing economic effects, not to mention Japan and South Korea. "
In the XNUMXs, the deceased, the guru of the Korean religious group "Unification Movement International (Unification Church)" (currently the Unification Movement International), became a strong proponent of the tunnel concept. There is also a history of exploratory drilling by related organizations.
Mr. Nagano said, "We should not deny that religious groups are involved, but we should make a choice. Some political figures are enthusiastic, such as former Minister of Justice Daizo Nozawa. Eventually, the Japanese and Korean governments agreed. , We must focus on government-led organizations. "
