From the wiki: “Yokohama Marine Tower was inaugurated in 1961 as one of the events celebrating the 100th anniversary of the opening of the Port of Yokohama to foreign trade. The latticed, skeletal tower was billed as ‘the tallest lighthouse in the world’ (although this depends on how one defines ‘lighthouse’) and, in clear conditions, visitors can see Mount Fuji from its 100-metre high observation deck.
“On December 25, 2006, Marine Tower temporarily shut its doors. Then the city of Yokohama took over ownership, to restore it. After the renovations, Marine Tower was reopened on May 23, 2009, in time for the city’s 150th anniversary celebrations.”
