Nasushiobara (那須塩原市) is a city in northern Tochigi prefecture, Japan.
The city was established in 2005 with the merger of the former city Kuroiso and the towns of Nishinasuno and Shiobara.
Nasushiobara is on the JR Tohoku Shinkansen line about an hour north of Tokyo. You can make the same journey by local trains in three and a half hours, though it might require a transfer in Utsunomiya.
The nearby town of Nasu is known for hot springs in the mountains.
