The world’s second highest building, the Tokyo Sky Tree (R), is pictured behind cherry blossoms at a Tokyo park on April 18, 2012. The 634-metre tower will open to the general public on May 22, with the main attraction being the two observation decks at 350 and 450 metres above ground. Tourism bosses in the country hope the Tokyo Sky Tree will prove a draw for foreign visitors, whose numbers plummeted in the aftermath of the quake and tsunami disaster last year and the nuclear crisis it sparked.
