Tokyo Tower is the highest construction in Tokyo (333m). It has two observatories, one at 150m, and the other one at 250m. Adults will pay 820 to access the first one, and additional 600 to reach the second.
Tokyo Tower also has a Wax Museum, Mysterious Walking Zone, Trick Art Gallery, shopping arcades and restaurants. But the most interesting side attraction is probably the Tokyo Tower Aquarium and its 50,000 fish composed of 800 species.
Tokyo Tower is open all year round from 9am to 10pm. It can be accessed from Akabanebashi (Oedo line), Kamiyacho (Hibiya line), Onarimon (Mita line), Daimon (Asakusa & Oedo lines) or Hamamatsucho (JR/Tokyo Monorail) stations.
