TheMinatomirai 21 Line (みなとみらい21線Minato-mirai-21-sen), commonly known as theMinatomirai Line (みなとみらい線Minatomirai-sen), is a subway line inYokohama,Japan that runs fromYokohama Station toMotomachi-Chūkagai Station through theMinatomirai 21 business district. The line opened in 2004 and is operated by theYokohama Minatomirai Railway Company.

Maps andstation numbering use navy blue and the route symbolMM to identify the line. The entire line is underground and goes under theMinato Mirai andKannai districts, as well as numerous islands made of softreclaimed land andchannels, requiring stations to be constructed deep underground. The original above-ground section of theTōkyū Tōyoko Line betweenYokohama andSakuragichō stations was abandoned and replaced with a new underground connector line to allowthrough services onto the newly completed Minatomirai Line.

All trains run from Yokohama Station toMotomachi-Chūkagai Station and vice versa, with no trains stopping and changing direction at any station in between.

Operations are managed byTokyu Railways, with no changing of staff at Yokohama Station; Tokyu staff (train drivers and conductors) continue to support the train over the Minatomirai portion of the line as well.Station-side staffing is provided by Minatomirai employees with the exception of Yokohama Station, which is managed by Tokyu Railways. Many Minatomirai employees are former employees of Tokyu Railways.Train management is controlled byYokohama Minatomirai Railway Company at an operational command center. Railway facilities are maintained by Yokohama Minatomirai Railway, but the actual maintenance work is contracted to Tokyu Railways employees.Because Yokohama Minatomirai Railway does not own its own rail yard, trains are parked overnight at Tokyu Railways' Motosumiyoshi Rail Yard and at Motomachi-Chūkagai Station. There are plans to construct a portion of track for parking additional trains underneathHarbor View Park starting in 2020.

The Minatomirai Line is essentially an extension of theTōkyū Tōyoko Line. The two lines operate as one, with no crew change at Yokohama station where trains cross between the two lines, in contrast to standard procedure with other line operators in Japan.

With the completion of the underground link line to theTokyo Metro Fukutoshin Line on March 16, 2013, Minatomirai Line trains run onto the Fukutoshin Line via the Tōkyū Tōyoko Line and beyond to theTōbu Tōjō Line,Seibu Yūrakuchō Line, andSeibu Ikebukuro Line.Along with the link to the Fukutoshin Line being established, Tōkyū Tōyoko and Minatomirai express trains (limited express/commuter limited express/express) were expanded from eight-car to ten-car configuration (with the exception of a portion of regular express trains). Platforms were extended at Minatomirai stations receiving express trains in order to be able to accommodate the extended ten-car configuration. Regular trains stopping at each station on the line continue to operate in the eight-car configuration.

All regular trains on the Minatomirai Line use the same services as the Tōyoko Line.

The S-train is the first service on the Minatomirai Line with fully reserved seating. On weekends and holidays it makes two and a half round trips (to Motomachi-Chūkagai Station twice and from the same station three times). All trains continue to the Seibu Ikebukuro Line, and one round trip begins and ends at theSeibu Chichibu Line'sSeibu-Chichibu Station.Within the Minatomirai Line, these trains stop at Minatomirai Station and Motomachi-Chūkagai Station, but tickets are not sold for final destinations at these stations.S-train services use theSeibu 40000 series train exclusively.

Limited Express (特急,Tokkyū) trains run during daylight hours during the week and at all times excepting early morning and late night on weekends and holidays. All services are operated by 10-car sets. Limited express trains stop at Yokohama Station, Minatomirai Station, and Motomachi-Chūkagai Station within the Minatomirai Line.

Commuter Limited Express (通勤特急,Tsūkin Tokkyū) operate during the morning rush hour and in the evening on weekdays. The trains use 10-car sets and stop at all stations on the Minatomirai Line with the exception of Shin-Takashima Station. Many trains continue to the Fukutoshin Line via the Tōyoko Line as Commuter Express services.

Express (急行,Kyūkō) operate all day long. The trains stop at all stations on the Minatomirai Line with the exception of Shin-Takashima Station. Most daytime trains use 8-car sets, but 10-car sets may be used during peak hours in the morning and evening.

Local (各駅停車,Kakueki-teisha) trains stop at all stations. 8-car sets are used to align with the Tōkyū, Yokohama, and Tokyo Metro lines.
