No trip to Japan would be complete without at least a glimpse of Mt. Fuji. Japan’s tallest mountain is also a UNESCO World Heritage Site and is visited by around 300,000 adventurous hikers each year. To fully experience the beauty of the mountain, you don’t necessarily have to reach the summit. From all over Tokyo and the surrounding areas, there are skyscrapers with observation decks and beautiful lakes that offer great day hikes with stunning views. The best time to see the mountain is early morning, especially on a crisp winter day when there isn’t a could in the sky.
