The Hanzōmon Line is a subway line operated by Tokyo Metro. It extends from Shibuya to Oshiage in Sumida and features direct through service at both terminus to other railway companies. At Shibuya almost all trains continue traveling on the Tōkyū Den-en-toshi Line to Chūō-Rinkan, while at Oshiage some train services are using the Tobu Skytree Line to Tōbu-Dōbutsu-Kōen and further to Minami-Kurihashi on the Tōbu Nikkō Line or Kuki on the Tobu Isesaki Line. It is the second shortest subway line in Tokyo, however due to through operations trains can go directly the 98.5 km distance between Chūō-Rinkan to Minami Kurihashi - the longest train service on a Japanese subway line. The Hanzōmon Line is also designed to have several transfer stations to the Ginza Line to relieve its limited capacity problem. Between Shibuya and Aoyama-Itchōme both lines run parallel. The line is named after the west gate of the Imperial Palace (Hanzōmon), which in turn is named after 16th century samurai Hattori Hanzō, who was important to the founding of the shogunate which built the palace.
