Toei Mita Line
The Toei Mita Line (都営三田線, Toei Mita-sen) is a subway line of the municipal Toei Subway network in Tokyo, Japan. The line runs between Nishi-Takashimadaira in Itabashi and Meguro in Shinagawa. Trains continue with direct service into the Meguro Line of Tokyu Corporation for Hiyoshi. The portion between Shirokane-Takanawa and Meguro is shared with the Tokyo Metro Namboku Line.
The line was named after the Mita district in Minato, Tokyo, under which it passes. On maps and signboards, the line is shown in blue. Stations carry the letter "I" followed by a two-digit number.
In fiscal year 2023, the Mita Line was Toei's second most profitable line, earning 6.30 billion yen in surplus (after the Asakusa Line). It served 606,811 passengers on average per day, the lowest in the Toei network.
Most platforms on the Mita Line are equipped with chest-height automatic platform gates that open in sync with the train doors. The line was the first in the Tokyo subway system to have low barriers. The section between Shirokane-Takanawa and Meguro, which is shared with the Tokyo Metro Namboku Line, has used full-height platform screen doors since its opening. As of April 2022, the platform doors have been fully replaced for 8 car operations.
The right-of-way and stations between Shirokane-Takanawa and Meguro are shared with the Tokyo Metro Namboku Line – a unique situation on the Tokyo subway where both operators share common infrastructure. Under an agreement of both parties, the fare for this section is calculated on the Toei system for passengers travelling to stations on the Mita Line past Shirokane-Takanawa, using the Tokyo Metro system for those travelling on the Namboku Line past Shirokane-Takanawa, and on the system "most beneficial to the passenger" (presently the Tokyo Metro schedule) for travel solely on the shared section.
According to the Tokyo Metropolitan Bureau of Transportation, as of June 2009, the Mita Line is the ninth most crowded subway line in Tokyo, running at 164%[a] capacity between Nishi-Sugamo and Sugamo stations.
The Mita Line was first envisioned in 1957 as a northern branch of Line 5 (the present Tōzai Line), serving the section between Ōtemachi and Itabashi. Under a revised proposal in 1962, the line was made independent and its construction was undertaken by the Tokyo Metropolitan Government. The new line (Line 6) was planned to run from Gotanda Station on the southwestern side of the Yamanote Line through central Tokyo, with its northern extensions via Yamatochō (大和町) in Itabashi (near present Itabashi-honchō), diverting to Kami-Itabashi and Shimura (志村) (present Takashimadaira). The southernmost portion, from Sengakuji to Nishi-Magome and Nishi-Magome depot, was to be shared with Line 1 (Asakusa Line); therefore, Line 6 would be 1,435 mm (4 ft 8+1⁄2 in) gauge.
Due to political considerations, the design of the Mita Line changed several times during the early 1960s. There were plans for it to run to Toda, Saitama, to serve a boat-racing venue for the 1964 Summer Olympics. The government of Saitama also proposed the construction of a new subway line which would allow through service on the Mita Line as far as Ōmiya Station. In 1964, these plans were changed to allow the Mita Line to connect with the Tōbu Tōjō Line via a branch to be built by Tobu between Yamatomachi (大和町) (now Wakōshi), and Shimura, the northern end of Line 6. At the southern end, the junction with the Tokyu network would be via a connecting line, which would be constructed by Tokyu from Sengakuji to Kirigaya (桐ヶ谷) on the Tōkyū Ikegami Line; the route would continue to the then-Den-en-toshi Line and finally west, down to Nagatsuta. As a result, the construction standards of Line 6 were based on those of Tobu and Tokyu (such as 1,067 mm (3 ft 6 in) gauge track and 20-meter-long cars – today, the Mita Line is the only Toei line to use this gauge). A depot was planned at Shimura, independent of the Nishi-Magome depot on Line 1.
