Isumu Railway
Construction of the railway was approved in 1925 following strong requests from local residents, and the JNR Kihara Line began operating in 1930. In 1987 the JNR was privatized, and East Japan Railway Co., Ltd. (JR East) took over. Then in 1988 the line was transferred to a local third-sector firm, Isumi Railway Co., Ltd. Local governments along the line are the main shareholders of this company, the head office of which is at Otaki Station, almost midway along the line.
The Isumi Railway, which covers a total distance of 26.8 km, has 14 stations, almost all of which are unmanned. The rolling stock, such as the Isumi 300 Series, is relatively new, although the company also operates various other projects. At weekends, for example, it runs the Restaurant KiHa gourmet train using old model KiHa 28 carriages.
Otaki, where the company’s head office is located, flourished as a castle town in the past. The lord of Otaki Castle was Honda Tadakatsu (1548–1610), a well-known figure in Japanese history who was one of the so-called four paladins serving the ruling Tokugawa clan. Maybe for that reason, there are many old but solid buildings in Otaki, and the townscape has a somewhat dignified atmosphere. Like the Kominato Railway, the Isumi Railway is nonelectrified and single track, and its stations are mostly modest and unmanned. Its popularity lies in its rich local color.
