Discover modern railways and colorful local lines in Chiba Prefecture, just a stone's throw from Tokyo. We start on "Japan's doorstep", at Narita Airport, riding the Shibayama Line into Chiba City and glide through the sky on the Chiba Urban Monorail, the world's longest suspended railway. Then we cross the prefecture on the Kominato Line, passing stations and bridges built more than 90 years ago, meet the people who saved the Isumi Railway from closing, and finally arrive at a menagerie of trains.
