Lake Ashinoko, also known simply as Lake Ashi, is a stunning crater lake nestled in the Hakone region of Kanagawa Prefecture, Japan. Formed nearly 3,000 years ago after the last eruption of Mount Hakone, this picturesque lake is a popular destination for both locals and tourists thanks to the plethora of activities and attractions in the nearby area.
The calm waters reflect the surrounding mountains, including the iconic Mount Fuji, on clear days, making it one of the most photographed spots in the country. While Mt. Fuji is rarely seen due to thick clouds, when it does show up, it does so marvellously, stunning all those lucky enough to catch it out of the veil of clouds it normally hides in. Many travellers book hotels in the Hakone area to maximise their chances of seeing Mt.Fuji.
