Abstract

The Imaichi Alluvial Fan is located in the western part of Tochigi Prefecture, Japan. This study suggests that fluvial terraces in the Imaichi fan area were formed 150, 120-110, and 60 ca ka. Fluvial terraces of the same period have been reported in the surrounding areas, suggesting that they may be climatic terraces formed in response to climatic changes.
