Definition
Myōkō (妙高) is a named limited‑express train service that has been operated by East Japan Railway Company (JR East) in Japan, primarily connecting the cities of Nagano and Niigata.
Overview
The Myōkō service commenced operation in the mid‑1990s as part of JR East’s effort to provide faster inter‑regional connections between the Chūbu and Kantō regions. The train runs on the Shinetsu Main Line and the Myōkō Haneuma Line, traversing a mountainous corridor that includes the vicinity of Mount Myōkō, after which the service is named. The service was particularly important for travelers moving between the inland Nagano Prefecture and the coastal Niigata Prefecture before the opening of the Hokuriku Shinkansen extension. Following the inauguration of the Shinkansen line, the Myōkō limited‑express service was gradually reduced in frequency and ultimately discontinued in 2015.
Etymology/Origin
The name “Myōkō” (妙高) derives from Mount Myōkō (妙高山), a prominent volcanic peak located in the region that the train serves. The use of the mountain’s name follows a common Japanese railway naming convention in which services are titled after notable geographic features along their routes.
