The Yūrakuchō Line (有楽町線 Yūrakuchō-sen ) is a mass rapid transit line in Tokyo, Japan, part of the Tokyo Metro system. The 28.3 km line connects Wakōshi Station in Wakō, Saitama with Shin-Kiba Station in Kōtō, Tokyo. On maps and signboards, the line is shown in gold, often taken as yellow; stations carry the letter Y and a two-digit number.
The proper name as given in an annual report of the Ministry, Ministry of Land, Infrastructure and Transport is Line 8 Yūrakuchō Line (8号線有楽町線 Hachi-gō-sen Yūrakuchō-sen ), but in the reports of Tokyo urban transportation plan, it is more complicated. The line number assigned to the section south from Kotake-Mukaihara to Shin-Kiba is Line 8, but that of north of Kotake-Mukaihara to Wakōshi is Line 13, which indicates the section is a portion of Fukutoshin Line which shares the same number.
The Yūrakuchō Line has inter-running counterparts on its northern side, both of which are "major" Japanese private railway companies in Greater Tokyo. One is the Tōbu Railway at Wakōshi, north to Shinrinkōen. The other is the Seibu Railway at Kotake-Mukaihara with its bypass line Seibu Yūrakuchō Line connecting to its main Ikebukuro Line, through trains north to Kotesashi or Hannō.
Semi-express (準急) services were introduced on the Yūrakuchō Line from June 14, 2008. These operate twice hourly between Wakōshi and Shin-Kiba. Between Wakōshi and Ikebukuro, semi-express trains stop only at Kotake-Mukaihara; between Ikebukuro and Shin-Kiba, trains stop at all stations. The semi-express services run between rush hours during the week, and more frequently on weekends and holidays.
All types are formed as 10-car sets.
