Minato Mirai 21, Waterfront district in Yokohama, Japan.

Minato Mirai 21 is a waterfront district in Yokohama, Japan, with tall towers of glass and steel along the bay. The area includes shopping centers, green spaces, and a marina where a historic sailing vessel sits at anchor.

The site was home to shipyards and railway yards until the 1980s when the city began transforming it into a new business and residential area. Work started in the late 1980s and continued for several decades.

The name Minato Mirai 21 was chosen by public vote in 1981 and means "Port of the Future in the 21st century". The district's street names follow their trees: Sakura-dori for cherry, Keyaki-dori for zelkova, Ichou-dori for ginkgo. The Kishamichi Promenade follows the original harbor railroad tracks, and the Nippon Maru, a four-masted sailing ship, is permanently docked as a museum.

The area sits about a 20-minute walk southwest of central Yokohama Station and is reachable via several train stops. Most buildings are accessible to wheelchair users and the pathways are wide and flat.

A ropeway connects two stations over the water and offers views of the harbor during the short ride. The Ferris wheel displays the time at night through lit patterns on its spokes.
