The Main Deck on the second floor of Tokyo Tower is an observation area that looks down over central Tokyo and Zojoji. From the windows, Mount Fuji is visible, and the floor includes transparent panels and panels that distort the view below. The deck sits at 150 meters on a 333-meter broadcast tower built in 1958, and a small shrine is located inside. Visitors with Top Deck reservations pass through this deck first, and on the way down they also pass through the Main Deck before reaching the ground.
