奈良線
As Kintetsu operates a "Nara Line" of its own, the line is often referred to as the "JR Nara Line" ("JNR Nara Line" prior to 1988). Strictly speaking, the Kintetsu Nara Line links Osaka and Nara (a counterpart to the Yamatoji Line), rather than Kyoto and Nara (connected primarily by the Kintetsu Kyoto Line). However, there are many through trains to the Kintetsu Nara Line from Kyōto Station, so "JR" is often appended for clarity. This was aided by the 1988 introduction of the official nicknames "JR Kyoto Line", "JR Kobe Line" (for parts of the Tōkaidō Main Line and San'yō Main Line) and "JR Takarazuka Line" (southern half of the Fukuchiyama Line) within the Urban Network, making the "JR Nara Line" construction a natural parallel, if unofficial, usage.
