See 'Diamond Fuji'

The phenomenon known as 'Diamond Fuji' occurs when sunset and sunrise align perfectly with the peak of Japan's highest mountain, creating a mysterious, jewel-like image. This twice-a-year occurrence is best viewed from Sunshine City's 60th-floor observatory, with its 360-degree views of Tokyo and surroundings. The exact date for 2014's second 'diamond' is November 16, but the effect can be seen a few days before and after that as well, always around sunset (expected at around 4.30pm).
