Minato Mirai 21 Operations

The Minato Mirai 21 district was born as a core project of the effort to strengthen the center of the City of Yokohama, by bolstering Yokohama’s autonomy, transforming the quality of its port functions and reallocating administrative functions of the Greater Metropolitan Tokyo area. The creation of a new city is underway, based on the threefold concept of a city of international culture that is active round the clock, a 21st century city of IT and a city that is kind to people and the environment, rich in water, green spaces and history.
