The Yokohama Landmark Tower (横浜ランドマークタワー, Yokohama Randomāku Tawā) is the third tallest building^[1] and fifth tallest structure in Japan, standing 296.3 m (972 ft) high. Until surpassed by Abeno Harukas in 2014, it stood as the tallest building in Japan. It is located in the Minato Mirai 21 district of Yokohama city, next to the Yokohama Museum of Art.^[3]

The building contains a five-star hotel which occupies floors 49–70, with 603 rooms in total.^[1] The lower 48 floors contain shops, restaurants, clinics, and offices. The building contains two tuned mass dampers on the (hidden) 71st floor on opposite corners of the building.^[4]

On the 69th floor there is an observatory, Sky Garden, from which one can see a 360-degree view of the city and, on clear days, Mount Fuji.^[5]

The tower contains what were at their inauguration the world's fastest elevators (installed by Mitsubishi Electric), which reach speeds of 12.5 m/s (41 ft/s)^[1] (45.0 km/h (28.0 mph)). This speed allows the elevator to reach the 69th floor in approximately 40 seconds.^[6] The elevators' speed record was surpassed by elevators of Taipei 101 (60.6 km/h, 37.7 mi/h) in 2004, but the speed of this elevator's descent is still the fastest in the world.^[7]

The building was designed by the architecture and engineering division of Mitsubishi Estate, now Mitsubishi Jisho Sekkei and Hugh Stubbins and Associates, later KlingStubbins.
