The Shin-etsu Line connects Takasaki Station in Takasaki City, Gunma Prefecture with Niigata Station in Niigata City, Niigata Prefecture.
In the past, a single line connected Takasaki Station to Niigata Station, but with the opening of the Shinkansen line to Nagano (now Hokuriku Shinkansen) in October 1997, the line between Yokokawa Station and Karuizawa Station, which runs parallel to the Shinkansen line, was discontinued. At that time, the remaining line between Karuizawa Station and Shinonoi Station was also transferred to Shinano Railway. In March 2015, the Hokuriku Shinkansen line extension between Nagano and Kanazawa stations opened for service, and management of the line between Nagano and Naoetsu stations was also transferred to Shinano Railway and Echigo TOKImeki Railway.
Currently, the Shin-etsu Line operating as JR EAST has three sections: between Takasaki Station and Yokokawa Station, between Shinonoi Station and Nagano Station, and between Naoetsu Station and Niigata Station. This DLC includes the section between Naoetsu Station and Niigata Station.
Omigawa(青海川) Station, located on the way to the station, is known as a station adjacent to the sea, along with Umi-Shibaura Station on the Tsurumi Line and Rikuzen-Otsuka Station on the Senseki Line, where you can watch the sun set over the Sea of Japan from the platform.The train runs along the seaside section of the Sea of Japan between Naoetsu Station and Kashiwazaki Station, and between Kashiwazaki Station and Niigata Station, it runs through the rural landscape that symbolizes Niigata as a rice-producing region.
