The Tokyo Tower (officially named “Japan Radio Tower”) is the second tallest structure in Japan at 332.9 meters (1,092 feet) high. A working radio and TV tower, it’s also home to four floors of attractions in its base and two observation decks. The Top Deck at 250m can only be visited via the Top Deck Tour, where you’ll enjoy the recently refurbished observation deck and an audio guide describing what you can see.
