Lake Ashinoko is surrounded by the mountains of Hakone. You can go for a drive or take a stroll, and you can also take the Pleasure Cruise to enjoy the splendid view from the lake.

The lake was formed by the steam explosion of Kamiyama around 3,100 years ago. It is a caldera lake with an altitude of 724 meters, circumference of 19 kilometers, size of 6.9 square kilometers, and a depth of 43.5 meters at its deepest point. A caldera lake is a lake that is made by rainwater accumulating in a depression or a part of a depression made by volcanic activity. The lake is surrounded by the mountains of Hakone, and there are popular sightseeing spots nearby such as the Hakone Sekisho (checkpoint) and Hakone Shrine, as well as hot springs. You can go for a drive or a stroll by the lakeside, or enjoy the view from the lake on the Hakone Sightseeing Cruise or Pleasure Cruise that connects Togendai Port, Hakone-machi Port, and Moto-hakone Port. The colorful Hakone mountains and Mount Fuji that can be seen from the lake is an excellent view.
