Lake Motosu is the westernmost and third largest of the Fuji Five Lakes, which are situated at the foot of Mount Fuji. Lake Motosu sits at an elevation of 900 meters, which is the same as nearby Lake Shoji and Lake Sai, suggesting that the three lakes in fact used to be just one. These lakes are said to have been divided by an enormous lava flow from Mount Fuji and remain connected to this day via underground waterways.
Activities on and around the the lake include fishing, hiking, boat trips, and a number of watersports, and there are a few campsites around its shores for visitors looking to spend the night.
The annual Fuji Shibazakura Festival is held in the area surrounding Lake Motosu. It takes place between April and May when fields of pink moss flowers bloom together, with the backdrop of the mighty Mount Fuji in the background.
There’s a regular Chuo Highway Bus between Tokyo’s Shinjuku and the Fuji Five Lakes area, with the trip taking approximately 2.5 hours.
