Look at photos of Tokyo, and you'll often see majestic Mount Fuji in the background. Unfortunately, you can't count on this breathtaking backdrop appearing while you're in Tokyo.

Between clouds in the sky and dust in the air, the mountain isn't visible for large portions of time. Improvements in air quality mean the mountain is more readily visible now than it has been in years, and Tokyo offers numerous viewing decks from which to see it. But still, you may not want to plan your trip around snapping that photo.
