Greetings From Japan

It is a great honor and pleasure for me as President of the Japanese Tunnel Association to send greetings to the 1974 Rapid Excavation and Tunneling Conference. Recently in Japan, the Japanese Tunnel Association was established as recommended by the OECD Advisory Conference on Tunneling. This is a central organization concerned with tunnel construction consisting of government authorities, universities' research institutes and construction firms as well as manufacturers of relevant materials and equipment. As I was chosen the first president of the newly-established Japanese Tunnel Association, I would like to avail myself of this opportunity to announce to you its establishment and its earnest wish to contribute to the development of tunneling technique not only in our country but also all over the world. At the same time, I cordially request your friendship and cooperation for the benefit of further development of tunneling techniques on both sides of the Pacific. At present, many tunnels are under construction in Japan. The total length of tunnels under construction for railways and highways is about 600km including the 54km Seikan Undersea Tunnel which connects the Main Island and Hokkaido. Naturally, for construction of such tunnels in Japan, we have introduced much equipment and technique from the United States and other foreign countries. Now with accumulated experience, we are confident to be able to furnish various useful information concerning tunnel construction.
