Traveling from Nan'yo to Koriyama, passengers can utilize the Yamagata Shinkansen and the Ou Line services. The Yamagata Shinkansen, specifically the Tsubasa service, operates on this route, offering a swift journey at speeds of up to 260 km/h (162 mph). The travel time on the Tsubasa train is approximately 30 minutes, making it a quick option for those traveling between these two cities.
In contrast, the Ou Line services provide a slower alternative, typically reaching speeds around 90 km/h (56 mph) and taking about 1 hour and 15 minutes for the same journey. While the Tsubasa service prioritizes speed with limited stops, the Ou Line serves more local stations and may allow for more scenic views along the way.
Both train types offer basic amenities; however, the Yamagata Shinkansen boasts more comfortable seating and onboard refreshments, making it a preferable choice for travelers who prioritize speed and comfort.
