The Minatomirai 21 Line (みなとみらい21線 Minato-mirai-21-sen), commonly known as the Minatomirai Line (みなとみらい線 Minatomirai-sen), is a subway line of the Yokohama Minatomirai Railway Company connecting Yokohama Station to Yokohama Chinatown through the Minato Mirai 21 development.

On maps and station numbering the line is identified by the color navy blue and the route symbol MM. The line was opened on February 1, 2004. The whole line is underground and goes through the Yokohama Minato Mirai 21 and Kannai Districts. The line passes though numerous islands made of soft reclaimed land and channels requiring the stations to be built very deep. The original surface alignment Tokyu Toyoko line between Yokohama and Sakuragicho stations were abolished and replaced with a new underground alignment to connect and allow for through services with the newly completed Minatomirai Line.

Through services with the Tokyu Toyoko lineEdit

Almost all trains in the Minatomirai Line through operate with the Tokyu Toyoko line. Essentially the Minatomirai Line is an extension of the Toyoko line. Operationally the two lines operate as one with no crew change at Yokohama station when trains cross between the two companies in contrast to what is done with other through operating services in Japan.
