The tallest communication/Observation tower in Japan.

This would be the tenth such tower I've visited in all my travels.

According to Wikipedia:
Tokyo Skytree 634.0 m
CN Tower 606.2 m Toronto, Ontario
Oriental Pearl Tower 467.9 m Shanghai, China
Stratosphere Tower 350.2 m Las Vegas (Did a roller coaster ride at the top.)
Tokyo Tower 332.6 m
Sky Tower 328 m Auckland, New Zealand
Space Needle 184 m Seatle ( very smoky, with compromised view)
Calgary Tower 190 m
Washington Monument 169.3 m
Kyoto Tower 131 m

Need to find one in Europe, possibly the Eiffel tower.
