Long ago, Nakanojo was an expanse of lakes. Further back in time, it was the sea. The area’s complex geology, strongly influenced by volcanic activity and subject to repeated deposition and erosion, piqued my interest. I decided to explore its steep and dynamic topography. I moved along rivers in the Agatsuma region, the source of life for people in ancient times, and collected river sand. Each grain of sand originated in the mountains, changed shape in the currents, and traveled, carrying its memories. What will these little travelers of eternity whisper to us?

Remarks: The Gunma Prefecture Nakanojo Civil Engineering Office has granted permission to collect and use river sand.
