Q and A Session

Concluding Remarks: Jacques Marion, Co-Chairman of Europe and the Middle East UPF


The IAED webinar of ILC2021 was held jointly by UPF of Europe and the Middle East and UPF Japan. The moderator, Mr. Robin Marsh, secretary-general of UPF-United Kingdom, presented the theme and noted that a tunnel between Korea and Japan would have profound effects in East Asia for peace and prosperity.

In his introductory remarks, Mr. Masayoshi Kajikuri, the chair of the International Highway Construction Foundation and chair of UPF-Japan, explained the origin of the International Peace Highway Project, which Rev. Dr. Sun Myung Moon, the co-founder of UPF, proposed in 1981 at the 10th International Conference on the Unity of the Sciences (ICUS) in Seoul. In his vision, the Japan-Korea Undersea Tunnel would be the terminus of international highways. Following the tunnel project’s inclusion in the Japan-Korea Summit in 2010, the foundation seeks to encourage a bilateral agreement between Japan and South Korea on the project and garner widespread support.

Dr. Yoshimitsu Nishikawa, a research fellow at the Institute of Social Sciences of Toyo University in Japan, proposed an undersea tunnel, over 230 kilometers in length, connecting the Japanese island of Kyushu with the South Korean city of Busan. He argued that an undersea tunnel would have a great effect on the economic development of the two countries, facilitating the transportation of tourists and the mutual exchange of energy, and would contribute to peace and stability in Northeast Asia.

Ms. Gözde Dizdar, the vice president of Centrist Asia Pacific Democrats International, Turkey, explained about the Marmaray Tunnel: It is the deepest immersed tube tunnel in the world with a depth of 60 meters, connecting the European and Asian sides of Istanbul across the Bosporus Strait. The construction by a consortium of Japanese and Turkish contractors had to overcome many challenges, including the seismic design for earthquake resistance of 7.5 Richter, the high ship traffic (50,000 ships a year), archeological findings, and political pressures.

Professor Roger Vickerman, emeritus professor of European economics at the University of Kent in the United Kingdom, spoke about the Channel Tunnel between England and France. Begun in 1987 and opened in 1994, the 50km tunnel system provides two types of services: shuttle trains for cars and trucks between terminals, and through rail services. For passengers, Eurostar high-speed trains link London with Paris and Brussels. As a piece of advice to Japanese participants, Professor Vickerman added that it was important to have clear support from a range of stakeholders, both nationally and locally, to build consensus – and to deal with environmental concerns.

Mr. Jacques Marion, regional co-chair of UPF Europe and the Middle East, ended the webinar by explaining the UPF founders’ vision underlying the Japan-Korea tunnel, which would be the first link of a Great International Highway that would run through China to the west and Russia to the north, helping to create a prosperous East Asian Economic Zone. It then would extend to Western Europe on the one hand, and to the United States and Canada on the other hand, by means of an undersea tunnel at the Bering Strait.




the international highway peace project featuring the japan korea tunnel proposal by dr katsumi otsuka 11 638In a mayoral election campaign in South Korea's second largest and southern city, Busan, a futuristic project for an undersea tunnel linking Korea and Japan was heatedly debated against the backdrop of the sour relations between the two most democratic and free economies in the Far East.

The project idea was proposed four decades ago, as a part of an international highway vision, by the co-founders of the Universal Peace Federation (UPF), Dr. Sun Myung Moon and Dr. Hak Ja Han Moon. As world-renowned peace makers, their proposal is beyond worldly politics. It aims at harmonious bilateral relations across the strait, enhancing a possible reunification of the divided peninsula, and eventually contributing to a wider free economic zone throughout East Asia and beyond. As the election heat has now cooled, the project may now receive the calmer contemplation it deserves as it may offer one of the ingredients for the peace, stability and prosperity for the nations of East Asia.

In this webinar we would like to consider if a tunnel project can contribute to that end? In fact, the extent to which the prospects for peace, stability and prosperity can be enhanced by means of an undersea tunnel can be examined in two cases. The first is the Marmaray Tunnel (as well as the later Eurasian tunnel) across the Bosporus Strait dividing Asia and Europe in Istanbul (Turkey). It connects the two continents thanks to significant technical and economic support from Japan.

The second is the Strait of Dover where the Eurotunnel had to overcome formidable historical and political hurdles between Britain and France. Once completed, however, the tunnel transformed the area's geographic features. Even after Brexit, Britain is bound with continental Europe in every way other than the European Union’s systems.

The webinar, being prepared by the UPF’s International Association for Peace and Economic Development in Japan and Europe & the Middle East, will listen to experiences and lessons from Turkey, Britain and France as well as to Japan’s views on the tunnel project.
