Lake Ashi sits at the foot of Mount Fuji and is a popular tourist destination. However, many other volcanoes around the world also have surrounding lakes, such as:
* Mount Vesuvius in Italy (Lake Avellino)
* Mount Etna in Italy (Lake Gurrida)
* Mount Kilimanjaro in Tanzania (Lake Chala)
* Mount Shasta in California, USA (Lake Siskiyou)
If you have a particular region or type of lake in mind, I might be able to give you a more specific answer.
