The route from Tokyo to Nan'yō is primarily served by the Yamagata Shinkansen, specifically the Komachi service. This train operates at speeds of up to 240 km/h (149 mph) and completes the journey in approximately 4 hours. Travelers can enjoy a comfortable ride with both Ordinary and Green class seating options available. The Komachi makes several stops at notable cities along the way, including Sendai and Yamagata, providing easy access to regional attractions.
The Yamagata Shinkansen also has another service, the Tsubasa train, which offers similar amenities and travel times, although it may have a slightly different schedule. While both trains provide a smooth travel experience, the Komachi is recommended for passengers looking for faster service and fewer stops. Passengers have access to onboard services, including refreshments and spacious seating, making the trip pleasant and enjoyable.
