Marine Tower, located by Yamashita Park in Yokohama Port, has long been treasured by the residents of Yokohama as the city's symbolic tower. It is also registered in the Guinness Book of Records as the tallest lighthouse in the world. 106 meters high (324 ft) and constructed with red and white iron steel placed in a cone, it is a beautiful site to behold, especially when lit up at night.
Marine Tower was built in 1958 as part of a special project to celebrate the 100th anniversary of the opening of Yokohama Port. The project was initiated by the City of Yokohama and individual volunteers who proposed to construct a monument for the occasion. This progressed into a plan to build a marine center, and eventually it was decided to build an observatory from where the whole of Yokohama could be seen. While the lighthouse design was originally chosen to represent Yokohama’s image as a harbor city, in the end the functions of an actual lighthouse were added, making the tower a landmark for ships sailing in and out of Yokohama. The name "Marine Tower" was solicited from local residents in 1960.
Marine Tower is also a popular tourist spot. The view from the observatory, located under the lighthouse room, is exceptional. It presents before you a 360-degree view of Yokohama, including the port, the Minato Mirai District, and the residential area.
Unfortunately, Marine Tower decided to close its doors on December 25, 2006 due to a decline in the number of visitors. However, due to strong demand from residents to preserve the building, the City has decided to buy the tower and restore it. After the renovations, Marine Tower was reopened on May 23, 2009, in time for the city's 150th anniversary celebrations.
