Why is the Eiffel tower in Tokyo, anyway?

As a result of watching too much old anime on Hulu, I started wondering just why there was a copy of the Eiffel tower sitting in the middle of Tokyo.  It seemed like an odd choice.  So-- to the Internet!  FOR JUSTICE SCIENCE FACTOIDS!

The Tokyo Tower was built in 1958, by an architect who really liked the Eiffel Tower.  Honestly, that's really most of the story.  Japan's public television network had been launched a couple of years earlier, and they decided that instead of building a whole bunch of smaller towers all over the place (which looked to be a likely outcome), they should just build one giant broadcast tower capable of covering the entire Kanto region (sort of the Tokyo Metropolitan Area).  The architect Tachu Naito was chosen, and he apparently decided to make a copy of the Eiffel Tower, only very slightly bigger (30 meters).  That extra height qualifies it as the world's "tallest self-supporting steel structure," for whatever that's worth.  It is the second tallest structure in Japan, as of this year, as the Tokyo Sky Tree approaches completion.  And according to the promotional materials at least, roughly one-third of it was built out of steel scavenged from US Army tanks damaged during the Korean conflict-- the primary source of quality steel at the time.

The aforementioned Tokyo Sky Tree, by the way, will take over most of the broadcasting responsibilities from the Tokyo Tower, leaving it to fulfill only the roles of Tourist Landmark and Giant Monster Target.
