the Five Lakes of Mt. Fuji
Refers to the five lakes around the northern base of Mount Fuji: Lake Kawaguchi, Lake Motosu, Lake Sai, Lake Shoji, and Lake Yamanaka. A well-known tourist destination.
The Fuji Five Lakes is the collective name for the five lakes located at the northern base of Mount Fuji.
I plan to go camping at the Fuji Five Lakes during summer vacation.
Compound of 富士 (Fuji, referring to Mount Fuji) + 五 (go, 'five') + 湖 (ko, 'lake'). The name directly describes the five lakes associated with Mount Fuji.
