The Yokohama Landmark Tower (横浜ランドマークタワー Yokohama Randomāku Tawā) is the second tallest building and 4th tallest structure in Japan, standing 296.3 m (972 ft) high. It is located in the Minato Mirai 21 district of Yokohama city, right next to Yokohama Museum of Art. Work on the building was finished in 1993. When built, it was the tallest building in Japan until it was surpassed by Abeno Harukas in 2012. When opened, it had the highest observation deck in Japan.

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.

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.

The tower contains what were at their inauguration the world's second fastest elevators, which reach speeds of 12.5 m/s (41 ft/s) (45.0 km/h (28.0 mph)). This speed allows the elevator to reach the 69th floor in approximately 40 seconds. The elevators' speed record was surpassed by elevators of Taipei 101 (60.6 km/h, 37.7 mi/h) in 2004.

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