Traveler reviews

Honestly, this is my favorite spot in the area if you want a great view of Fuji without the massive crowds. I loved that it wasn't completely deserted, but it’s definitely not chaotic like some of the other lakes. The best part for me was just walking a bit further down the path away from the main parking area. Once you get a little distance, it’s so peaceful and you get these perfect, clear reflections of the mountain on the water.
