Lake Yamanakako is located in the village of Yamanakako in Yamanashi Prefecture near Mount Fuji, Japan. It is the largest of the Fuji Five Lakes in terms of surface area, and is the highest of the Fuji Five Lakes in terms of elevation. The lake offers majestic views of Mount Fuji especially from its less developed northern shores.
Panorama Dai, an observation point halfway up the mountains and southeast of the lake, is a popular spot to view Mount Fuji and the lake. It is also served by a small car park. However, it is not connected with any local transport. You can either drive there or walk from the "Mikuniyama Hiking Course Iriguchi" bus stop which takes about half an hour.
Lake Yamanakako is well connected with buses from the Kawaguchiko Station. There are also Fujikko tourist buses that depart from Fujisan Station and make an entire circle around Lake Yamanakako.
I visited Fuji in mid-April when the cherry blossoms were in full bloom. I stayed at Hotel Mystays Fuji Onsen Resort and with the help of a tour guide, checked out the best spots for 'sakura' or cherry blossom viewing with Mount Fuji in the background. Even though the cherry blossoms had still not opened at Lake Yamanakako, my tour guide felt that I should visit the lake anyway for the best sunset views on Mount Fuji. I think the pictures say it all!
