Chikatetsu-Narimasu

The Tokyo Metro Yurakucho Line ( 東京地下鉄有楽町線 Tōkyō Chikatetsu Yūrakuchō-sen ? ) is a subway line in Japan owned and operated by the Tokyo subway operator Tokyo Metro . The line connects Wakōshi Station in Wakō, Saitama and Shin-Kiba Station in Kōtō, Tokyo . On maps, diagrams and signboards, the line is shown using the color "gold" ( ), and its stations are given numbers using the letter "Y". The proper name as given in an annual report of the Ministry of Land, Infrastructure and Transport is Line No. 8 Yūrakuchō Line ( 8号線有楽町線 Hachi-gō-sen Yūrakuchō-sen ? ) . [2] According to the Tokyo urban transportation plan, however, 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.
