Satsuma Province was home to an unusual rock formation known as The Two Sword Rock (Sokenseki). Located by the busy port of Bonotsu, the rock formation earned its name from its blade-like shape. If one were to visit this rock today, it would be clear that Hiroshige took liberties in the height and shape of the rocks in the design. However, as the travelers look up from the boat in wonder at the towering stones, Hiroshige conveys the excitement of experiencing a natural wonder rather an accurate topographical image. Today, the former Satsuma Province belongs to western Kagoshima Prefecture.
