Many of Nagaoka's prints from the late 1970s are visual explorations of the volcanic landscape of his childhood home near Mount Azuma in central Honshu, Japan. He peels away the layers of lava and ash, creating a trench that exposes the bedrock, deep beneath the surface. Nagaoka commented about his work of this period: "The menace of the volcano consolidates a knowledge of the powerless dependence of the whole existence of my family who were so close to the land. After a landslide I see in the thin layers of the ages, the finality of all life and the new rice from the deadly ash."
"Horizon" refers to a line marking the apparent junction of the physical planet and the sky. "Horizont Missoon" is German for 'Horizon Mission' a term used by NASA for methodology regarding identifying and evaluating innovative technology.
