This video tackles the challenging sections of National Route 1: "Satta Pass," "Utsunoya Pass," and "Sayo-no-Nakayama." ① Why was this route necessary? ② How did such a complex terrain form in the first place? These two points were the main themes of our investigation and analysis. We will explore the secrets of the route from both a topographical and geological perspective. We will drive from Shizuoka City, Shizuoka Prefecture, through Fujieda City, to Shimada City.
