Yokohama Marine Tower (横浜マリンタワー Yokohama Marin Tawā?) is a 106 metre high (348 ft) lattice tower with an observation deck at a height of 100 metres in Naka Ward, Yokohama, Japan.

The light characteristic is marked by a flash every twenty seconds, whereby the light's colour is alternating red and green. Originally, at night, the tower shaft itself was lit green and red according to its markings, but now, after the reopening on May 2009, the lights are white.[3]


Yokohama Marine Tower was inaugurated in 1961. The Marine Tower is billed "the tallest lighthouse in the world",[4][5] although this depends on what lighthouses are considered.[6] In clear conditions, visitors can see Mount Fuji from the 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.[5][7][8]
