Lake Kawaguchiko is a picturesque lake located at the base of Mount Fuji, offering stunning views of the iconic mountain. It's a popular spot for tourists with various attractions like hot spring baths, museums, and boat tours. The best views of Mount Fuji can be enjoyed from the northern shores, especially during cherry blossom season in mid-April and autumn colors in early November. Just keep in mind that the mountain isn't always visible due to clouds, so try to catch it in the early mornings or late afternoons for the best chance of a clear view.
