You can´t miss Kyoto Tower. It is standing tall above the city, opposite the Kyoto station.
I t is built in 1964 and is 131 m high. The observationdeck is 100 m high.
The admission fee is like the tower: skyhigh!
Fun Alternatives: If you go to the top of Kyoto station there is a free observation deck. And the views from the skywalk in Kyoto station are also great!
Kyoto Tower is OK if you are in a BIG hurry and don't have time to shop for other souvenirs, but you can have a much better (and more interesting) time in areas like Higashiyama (eastern Kyoto) or even the Kyoto Craft Center
