Thank you for viewing. There is some age-related soiling. In the past, the underground space was another world for humanity to nurture life and weave dreams. Humans drew pictures in caves and dug tunnels in the late Paleolithic period 20,000 years ago, excavated flint, and also had a long history of setting SF-like dreams in the underground. And now, the underground, along with space and the ocean, has revived before us as a large space that holds the most modern construction themes. Today, the development and utilization of the underground is a common global issue, and especially in Japan, which has a small land area, it can be said that it is a theme that we should take on as an adventure. As one of those "calls," this issue focuses on the underground and reconfirms what the underground can be.
