Local services on the Myōkō Haneuma Line use a fleet of ten ET127 series 2-car electric multiple unit (EMU) trains transferred from JR East.[2] These have reinforced front-end skirts, and feature a new livery.[2] They operate as two- or four-car formation during the off-peak periods, and as six-car formations during peak periods.[2] Shirayuki limited express services operated by JR East use four-car E653-1100 series EMUs.[2]

Since 4 July 2021, Rapid service which uses 413 series and 455 series has been commenced operating on Myoko Haneuma Line on only holidays.

While the western boundary of the Nihonkai Hisui Line is at Ichiburi Station, most services on the line operate between Naoetsu and Tomari on the Ainokaze Toyama Railway Line. At Tomari Station, both ETR trains and Ainokaze Toyama Railway trains use platform 2, allowing a same-platform transfer.[2] The Express service on only holidays which uses 455 series and 413 series has been commenced operated since 4 July 2021, and boarding on this service costs 500 yen.[4]

All stations are in Niigata Prefecture.

The eastern section of the line is electrified at 1,500 V DC and the western section of the line is electrified at 20 kV AC (60 Hz) overhead, with a dead section separating the two different power supplies between Itoigawa and Kajiyashiki stations, but in order to eliminate the need to procure new dual-voltage rolling stock, local services on the Nihonkai Hisui Line use a fleet of eight new ET122 single-car diesel multiple unit (DMU) trains based on the JR West KiHa 122 series design.[2] This fleet includes two special-event cars.[2] Services normally operate as single-car trains during the off-peak periods, increased to two cars during the peaks.[2]

Until March 2017, a seasonal limited-stop "Rapid" service operating between Niigata and Itoigawa ran once a day in each direction using a 6-car JR East 485 series EMU.[2][5]

Since 4 July 2021, Express service which uses 413 series and 455 series has been commenced operating on Hisui Line on only holidays.
