The Japanese national network operated by [[Japan Railways Group]] employs narrow gauge {{RailGauge|1067mm}}. The maximum allowed width of the rolling stock is {{convert|3000|mm|ftin|abbr=on}} and maximum height is {{convert|4100|mm|ftin|abbr=on}}; however, a number JR lines were constructed as private railways prior to nationalisation in the early 20th century, and feature loading gauges smaller than the standard. These include the [[Chūō Main Line]] west of [[Takao Station (Tokyo)|Takao]], the [[Minobu Line]], and the [[Yosan Main Line]] west of [[Kan'onji Station|Kan'onji]] ({{convert|3900|mm|ftin|abbr=on|disp=or}} height). Nevertheless, advances in [[Pantograph (rail)|pantograph]] technology have largely eliminated the need for separate rolling stock in these areas.

There are many private railway companies in Japan and the loading gauge is different for each company.<ref name = "Kubota">{{Cite book | author = Hiroshi Kubota | title = Railway Engineering Handbook | pages = 148 | publisher = Grand Prix publishing | isbn = 4-87687-163-9 | date = 13 February 1997 | language = ja}}</ref>
