TheNasuno (なすの, "field of Nasu") is a train service operated on theTōhoku Shinkansen byEast Japan Railway Company (JR East) in Japan.[1] It serves all stations betweenTokyo andKōriyama, a medium-sized city approximately 225 km north of Tokyo.[2]
The nameNasuno is derived from the Nasu Highlands (那須高原) and Nasu Onsen (那須温泉) areas located alongside the Tōhoku Shinkansen between Utsunomiya and Kōriyama.
There are approximately 16 returnNasuno trains daily, starting/terminating either atOyama, Nasushiobara, or Kōriyama.Nasuno services stop at all stations en route. Double-deckerNasuno services formed ofE4 series sets also operated up until September 2012, namedMax Nasuno.

The nameNasuno was first introduced on 22 September 1959 for semi-express (準急,junkyū) services operating betweenUeno in Tokyo andKuroiso on theTōhoku Main Line. In 1966, this was upgraded to become an express (急行,kyūkō), and on 14 March 1985, it was upgraded to become aLimited express using185 series EMU rolling stock. From 10 March 1990, the train was rerouted to operate betweenShinjuku in Tokyo and Kuroiso.[5]
On 10 December 1995, the name was adopted for the new all-stations services on theTōhoku Shinkansen.[1] TheTōhoku Main Line services to and from Shinjuku were renamedOhayō Tochigi andHometown Tochigi from this date. Prior to 1995,Aoba services formed the all-stations services along the whole line. However, with the introduction of short-distanceNasuno services,Aoba services were reduced, and in 1997, discontinued altogether, with the local services covered byNasuno as far as Kōriyama, and all further stations served by theYamabiko.
