Yes, you can see Mt. Fuji from the Tokyo Skytree, but visibility is entirely dependent on the weather and air clarity. On a clear day, the snow-capped silhouette of Japan's tallest mountain is visible to the west, approximately 100 kilometers (62 miles) away. The best time for a sighting is during the winter months (December to February) when the humidity is low and the air is crisp and dry. Early morning is the ideal time of day, as the sun illuminates the mountain from behind the tower, and afternoon haze has not yet settled over the Kanto Plain. The observation decks at 350 meters and 450 meters offer a panoramic view of the entire city, with Fuji often appearing as a majestic, distant triangle rising above the urban sprawl. If the horizon is cloudy or foggy, however, the mountain will be completely obscured, so checking a "Fuji visibility" forecast or a live cam before buying tickets is a smart move.
