Standing at 106 metres tall with an observation deck at 100 metres, Yokohama Marine Tower is the tallest lighthouse in Japan. Constructed in 1961, the lighthouse is known for its distinctive flash of alternating red and green lights inbetween a twenty second interval. Yokohama Marine Tower has carved itself out as a national icon through its fairly extensive media appearences, ranging from Godzilla blockbusters, to Digimon. Once proclaimed the tallest lighthouse in the world, on a clear day visitors can make out the beautiful sight of Mount Fuji.
