Tokyo Sky Tree's giant shadow

Tokyo Sky Tree, opened to the public in May last year, with its 634 meters is the tallest tower and the second tallest construction in the world. But why the builders chose to make it 634 meters tall? They wanted a height to be easily remembered and, by using old Japanese numbering, "634" can be read as mu-sa-shi, the name of the old Musashi Province - which included the tower's location, the Sumida ward from Tokyo.

While visiting Tokyo Sky Tree, one of the views I enjoyed a lot was from the first observation deck (located at the height of 350 meters) towards the Sumida River. The tower's giant shadow cast over the city is quite impressive and you can easily identify the first observatory, the second observatory (located at 450 meters) and the 184 meters antenna.
