Around the beginning of 2007, Professor Yorinaga Utsunomiya, who used to work in the chemical plant division of Mitsubishi Heavy Industries and currently runs a cram school in Echizen City, Fukui Prefecture, came to the Tokyo Metro Nishikasai near my home. He suddenly visited me at the station.
He started working as a site supervisor at Fujita Kogyo (currently Fujita, a general construction company, and as some of you may remember, the soccer team won the Emperor's Cup twice and was the predecessor to Shonan Bellmare) in 1977. We have been close friends since around 1999, and later on, when we were designing the world's largest crane ship, Kaisho (4,100 tons) at Takeishi Design Office, he even helped us.
Suddenly, he came to visit us and wrote a daring note about how Gentaro Kajikuri (formerly of Maeda Corporation), Chairman of the International Highway Construction Corporation (predecessor of the International Highway Foundation), encountered a Jaguar at Nabireki in Brazil and casually passed him by. Mr. Kajikuri handed it to me and told me that the continuation of the Japan-Korea Tunnel Nagoya Incline had finally begun to be dug.
That's all he told me, and he said 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 I kept thinking to myself, ``So, what are you going to do?'' ?'' the voice kept ringing, and it was not calm.
From that day on, I began looking for copies of the construction plan for the 1,200-meter Nagoya Survey Diagonal of the Japan-Korea Tunnel, which had been prepared in 1983 with the cooperation of Mitsui Construction (now Sumitomo Mitsui Construction), 30 years ago. Surprisingly, the president of Nippon Basic Technology, where I currently work (at the time, was deputy general manager of the technology headquarters), had it. It is an old, handwritten, yellowed document that is 50mm thick. They were also stored on a nearby shelf. The reason is a mystery.
However, Mr. Oda, the sales manager of Kawasaki Geology, and Mr. Amma, who first participated in the marine survey of the Japan-Korea tunnel and who continued to provide guidance, are said to be his seniors at Tokai University. There was. It would be Tenyu.
When I sent the plan to the address where the Karatsu office of the International Highway Construction Corporation used to be, it was returned to me.
In 2010, I heard that the Japan-Korea tunnel symposium was being held at the Kaiun Kaikan, and from then on I started going there.As I was about to leave after attending the second lecture in Shinjuku, I heard someone from behind say, ``Isn't that Mr. Takeishi?'' ?” I was stopped.
It was Masuo Oe, Executive Director (current Chairman) of the International Highway Foundation, who I was meeting for the first time in 24 years.
