Railway line in Japan
The Tobu Isesaki Line (東武伊勢崎線, Tōbu Isesaki-sen) is a Japanese railway line operated by the private railway company Tobu Railway, extending from Tōbu-Dōbutsu-Kōen Station in Saitama to Isesaki Station in Gunma Prefecture. The Isesaki Line can refer to the entire section between Asakusa - Isesaki and Oshiage - Hikifune, but from March 2012, the 41.0 km (25.5 mi) section south of Tōbu-Dōbutsu-Kōen was branded as the Tobu Skytree Line in conjunction with the opening of the Tokyo Skytree tower.
