Its official name is the , but it is referred to as on Tobu signage and publicity information. The Tojo Line and Tobu Ogose Line branch are isolated from other Tobu lines, such as the Isesaki Line and Nikko Line; some trains can however be transported between the Tojo Line and the rest of the Tobu network via the track connections with the Chichibu Main Line while on the ATS-Chichibu-type. There was a plan to connect between Nishiarai on the Isesaki Line and Kami-Itabashi on the Tojo Line, but this was never built. The name of the line comes from the original plan to construct a line linking with (an old province now Gunma Prefecture).
