Grand-Opening of the Tokyo Sky Tree will be on May 22, 2012. And Starting from today 3/22, we can purchase tickets to the observatory privately to the specified date and time through drawing. (haha, rough information)
It it a very tall (approximately 634 meters which is 2,080 feet) telecommunications tower; broadcasting, restaurant, and observatory; the tallest tower in the world and it will be lit by LED lighting and look like a mix between the Eiffel Tower in Paris and the Space Needle in Washington state, haha except the surprising height. To tell the truth, I haven't even been to Tokyo Tower and I wish I will be able to have a chance to visit them in Tokyo someday.
This site has detailed information of the tower itself. Whew, I wonder how the view would be like from the observatory with that height♪♪♪
