2 Japan-Korea Tunnel Technical Committee (1)

February 4th of this year (2017) marked the 50th anniversary of Yasuo Kuwahara's death.

Professor Yasuo Kuwahara was a civil engineer and railroad man who proposed the grand idea of ​​connecting Japan and the continent through an undersea tunnel and connecting it to Europe by railway around 1945. He was a courageous man who acted regardless of his wishes, even though he had the reputation of being a ``Horahara blowhard'' due to the grandeur of his ideas.

The railway network surrounding the Sea of ​​Japan is also part of this effort, and the Seikan-Kanmon-Japan-Korea-Soya Strait tunnel project was developed, and for the Japan-Korea tunnel project, two boring geological surveys were conducted near Higashimatsuura District, Saga Prefecture. To tell.


He was probably the first engineer in history to seriously plan a Japan-Korea tunnel.


Last year (2016), the Shinkansen finally connected to Hakodate, Hokkaido. Yasuo Kuwahara's plan, which was nicknamed the ``Honara'', became a reality with two strait tunnels: the Kanmon Strait Tunnel and the Seikan Strait Tunnel. Professor Yasuo Kuwahara is from Ishikawa Prefecture. It was with deep emotion that Professor Utsunomiya came from the same Hokuriku area with news of the resumption of the Japan-Korea Tunnel Project.


Now, let's get back to the story of my reunion with International Highway Foundation Executive Director Oe (currently Chairman).


Director-General Oe later came to me with a wonderful story that really got my blood pumping. There is a huge amount of data compiled from geological and environmental surveys on land and sea conducted by the International Highway Construction Corporation (predecessor of the International Highway Foundation) 30 years ago for the construction of the Japan-Korea Tunnel, but it is hardly ever utilized. do not have. We would like to establish a ``Japan-Korea Tunnel Technical Committee'' by gathering professional engineers with practical experience who can decipher and utilize this vast amount of data. That's what he wanted me to do.


Of course, I have no reason to refuse. I readily agreed. I couldn't resist the urge to quickly see the huge amount of data that had been organized.
