context_page_description: The Toei Mita Line is a subway line of the Tokyo Metropolitan Bureau of Transportation 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.
context_section_description: 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 Tokyo Metro Namboku Line has used full-height platform screen doors since its opening. As of May 2020, the platform doors are being overhauled for future 8 car operation.
  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 traveling 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% capacity between Nishi-Sugamo and Sugamo stations.
