Hora Actual en Shimo-tsuma, Japón — JST.

Due to motorization beginning in the 1960s, the completion of the Meishin Expressway, the debut of Boeing 727 planes on domestic flights in Japan, and the depopulation of rural areas, many railway lines in Japan have been forced to close down due to lack of riders and increased costs to maintain the lines. With Japanese National Railways (JNR) building more and more infeasible lines, along with additional Shinkansen lines such as the San'yō Shinkansen, nearly all JNR lines – except for those in the Tokyo area and Shinkansen lines – fell into deficit, putting the existence of JNR at risk. This resulted in movements to close such infeasible railway lines owned by the JNR, such as those known as the Deficit 83 Lines and Specified local lines.
