Minato Mirai 21, often known as simply Minato Mirai and abbreviated as MM, is the central business district of Yokohama, Japan. Initially developed in the 1980s, Minato Mirai 21 was designed as a large master-planned development and new urban center planned to connect Yokohama's traditionally important areas and commercial centers of Kannai and the Yokohama Station area.
Today, Minato Mirai is a major center for business, shopping, and tourism, attracting visitors and businesspersons throughout the Greater Tokyo Area. The business district is host to several major hotels, office towers including the Yokohama Landmark Tower, the Pacifico Yokohama convention center, art museums, and numerous cafés and shops in shopping centers and along its central pedestrian mall. The area continues to be developed as originally envisioned in the 1980s.
