History
The entire line was opened on October 14, 1969, after over two years of construction, considerably shortening the travel time between Chichibu and Tokyo. Twenty years later, on April 1, 1989, a connection opened to the Chichibu Railway's Chichibu Main Line, and through service began. On March 28, 1996, freight services between Higashi-Yokoze freight terminal and Shin-Akitsu (on the Seibu Ikebukuro Line) ceased. On March 12, 2003, "wanman" (one man) driver only operation began. Until March 8, 2020 there were two Rapid Express round trips from Ikebukuro bound for Nagatoro and Mitsumineguchi.
