There are Five lakes overlooking Mount Fuji in the Yamanashi Perfecture, I was actually going to another lake but when we got to the bus, Kawaguchi Lake which is about 100km away from Tokyo, There is a bus from Shinjuku Bus Station which takes about 2 hours to get there with very nice scenery along the way.
Favourite spots:
There was a few interesting spot to visit actually around this town but I just fell in love with the scenery of the Mount Fuji and stayed there until dusk.
What's really great:
It was very quiet town, there wasn't many car except on the way back to the bus station there was a pretty bad jam. But it was a very nice town to walk around for a day.
Sights:
Mount Fuji over the Kawaguchi Lake
Restaurants:
We ate in this Japanese Restaurant Hotel, can't remember the name but it has got a very good view of Mount Fuji.
