芦ノ湖[ Ashinoko ]Lake Ashi

Lake Ashi (芦ノ湖, Ashi-no-ko), also referred to as Hakone Lake or Ashinoko Lake, is a scenic lake in the Hakone area of Kanagawa Prefecture in Honshū, Japan. It is a crater lake that lies along the southwest wall of the caldera of Mount Hakone, a complex volcano that last erupted in 1170 CE at Owakudani. The lake is known for its views of Mt. Fuji and its numerous hot springs. A number of pleasure boats and ferries traverse the lake, providing scenic views for tourists and passengers. Several of the boats are inspired by the design of sailing warships.
