Hakone and Lake Ashi (Kanagawa Prefecture) Complete Guide | Tourism, Access, History, and the Charm of the Four Seasons Explained in Detail
What is Lake Ashi? Basic Information About Kanagawa Prefecture’s Largest Lake
Lake Ashi (Ashinoko) is located in Hakone Town, Ashigara Shimogun, Kanagawa Prefecture, and is the largest lake by area in Kanagawa Prefecture. Known as a caldera lake of the Hakone volcano, it is situated at a high altitude of 724 meters above sea level. The lake’s circumference is approximately 19 kilometers, its area is approximately 7.1 square kilometers, and its maximum depth reaches approximately 43.5 meters.
As a central hub of Hakone tourism, it is a scenic spot visited by numerous tourists throughout the year. On clear days, the majestic Mount Fuji can be seen beyond the lake’s surface, making it one of the most popular scenic spots in the Kanto region.
Formation and Geological Characteristics of Lake Ashi
Lake Ashi was formed approximately 3,000 years ago as a dammed lake when Mount Kamiyama of the Hakone volcano collapsed, and the resulting sediment blocked the Hayakawa River. Located in the crater plain of the Hakone Caldera, it is also a precious natural heritage that conveys the history of volcanic activity.
The lake water is highly transparent, and fish species such as Himemasu and black bass inhabit it, making it known as a fishing spot. Additionally, hot springs well up from the lake bottom in some areas, testament to Hakone’s abundant geothermal activity.

The Charm of Lake Ashi Through the Four Seasons
