1. In the beginning

Around the beginning of XNUMX, Professor Juncho Utsunomiya (Yorinaga), who was formerly in the chemical plant division of Mitsubishi Heavy Industries and currently runs a cram school in Echizen City, Fukui Prefecture, was in charge of Tokyo Metro Nishikasai near my home. I came to visit the station.

He was the on-site director at Fujita Corporation (currently Fujita, the so-called general contractor of the general construction industry, as you may remember, the soccer team won the Emperor's Cup twice at that time, the predecessor of Shonan Bellmare). He was a close friend of mine, and he helped me when he was designing the world's largest crane vessel "Kaisho" (XNUMXt suspension) at Takeishi Design Office.

 

A bold memorandum that he suddenly visited and the chairman of the International Highway Construction Corporation (predecessor of the International Highway Foundation) Gentaro Kajiguri (former Maeda Corporation) encountered Jaguar in Nabreki, Brazil, and passed by in a straightforward manner. Kajiguri-sensei told me that he had finally begun to dig the continuation of the Nagoya Castle Ruins in the Japan-Korea Tunnel.

He told me only that, and he was on his way to a study session where cram school managers from all over the country gathered, and he left like the wind, but in my heart, "So, what are you going to do?" The voice continued to ring, and it was not calm.

 

On that day, XNUMX years ago, I started looking for a copy of the construction plan for the XNUMXm Japan-Korea Tunnel Nagoya Survey Slope, which was created in XNUMX with the cooperation of Mitsui Construction (currently Sumitomo Mitsui Construction).That was owned by the president of Japan Basic Technology, where I currently work (at that time, the deputy general manager of the Technology Division).It is an old handwritten yellowed material with a thickness of XNUMX mm.It was also stored side by side on a familiar shelf.The reason is a mystery.

 

However, Kawasaki Geological's Oda Sales Manager and Dr. Yasuma, who first participated in the oceanographic survey of the Japan-Korea Tunnel and continued to guide them, are said to be seniors at Tokai University. There was.It will be Tensuke.

I sent the plan to the address where the International Highway Construction Corporation Karatsu Office used to be, and it came back.
In XNUMX, I heard that the Japan-Korea Tunnel symposium was at the Kaiun Kaikan, and from that time I started to visit, and when I tried to attend the second lecture in Shinjuku and go home, I heard from behind, "Isn't it Mr. Takeishi? Was it stopped.

 

It was Mr. Masuo Oe, Executive Secretary (currently Chairman) of the International Highway Foundation, who I met for the first time in XNUMX years.
