Tokyo Skytree is the city's newest monument and the tallest structure in Japan. The Skytree is located just east of the Sumida River and Tokyo's largest Buddhist temple, Senso-ji. At the base of the tower, is the Sumida Aquarium and a slew of shops and restaurants. The tower boasts two observation decks with views of the sprawling city and on a clear day Mount Fuji. For impeccable multi-course Japanese dining with views of the Skytree try La Sora Seed.
