The Moonlight Nagara (ムーンライトながら) was a seasonal rapid overnight train service operated by East Japan Railway Company (JR East) and Central Japan Railway Company (JR Central), which ran from Tokyo to Ōgaki in Gifu Prefecture via the Tokaido Main Line.

[1][2] Since the train service had not operated during the summer and winter of 2020 due to the COVID-19 pandemic, this announcement caused 29 March 2020 to be the final run of the Nagara.

From December 2013, Moonlight Nagara services were formed from 185 series electric multiple unit (EMU) 10-car (4+6-car) formations based at Omiya Depot.

[4] Additional Moonlight Nagara 91 and 92 trains also operated during busy seasons, and these comprised ten-car 183 series EMU sets owned by JR East and based at Tamachi Depot.

The name was taken from the Nagara River in Gifu Prefecture, and was formerly used for a semi express service which ran between Tokyo and Ōgaki from 1 June 1960 until 1 October 1965.
