# Ryōmō Line

The Ryōmō Line (両毛線, Ryōmō-sen) is a Japanese railway line connecting Oyama in Tochigi Prefecture with Maebashi in Gunma Prefecture. 84.4 km (52.4 mi) long, the line is owned and operated by the East Japan Railway Company (JR East). The name refers to the fact that Gunma and Tochigi prefectures were once part of an ancient province called Keno (毛野), which was later split into Kōzuke (Gunma) and Shimotsuke (Tochigi). This line connects both halves of the old province.

## Services

Most Ryōmō Line services continue beyond Shin-Maebashi and terminate at Takasaki on the Joetsu Line. Local trains run once an hour during the day between Oyama and Maebashi (more frequently between Maebashi and Takasaki). Some rapid services from Ueno and the Shōnan-Shinjuku Line have through-service to the Ryōmō Line, after which they stop at every station.
Prior to its discontinuation in 2021, Akagi limited express services, branded Swallow Akagi on weekdays, ran between Maebashi and Ueno or Shinjuku.

## History

The Oyama to Kiryu section was opened in 1888 by the Ryomo Railway, and extended to Shin-Maebashi the following year. The company merged with the Nippon Railway in 1897, and that company was nationalised in 1906.
