The Yamaguchi Line (山口線, Yamaguchi-sen) of Seibu Railway is a 2.8 km manually-driven rubber-tyred people mover that runs between Tamako in Higashimurayama, Tokyo and Seibukyūjō-mae in Tokorozawa, Saitama in Japan. The line has an official nickname Leo Liner, after 'Leo', the hero of Kimba the White Lion, who is also the mascot of Saitama Seibu Lions baseball team. The line is the only people mover that is operated by one of Japan's major private railway companies.


In 1950, the predecessor of the line opened as an attraction ride called Fantasy Train (おとぎ列車, Otogi Ressha), running through the amusement area developed by Seibu Railway and its allies. Battery-powered locomotives were used at the time, running on 762 mm (2 ft 6 in) gauge track. In 1952, it legally became a train line, with the official name Seibu Yamaguchi Line. In 1984, the steam and battery powered railway closed, The next year, the new people mover line opened, mostly along the same route.
