The route from Ueno to Nan'yo is primarily serviced by the Yamabiko and Hayabusa Shinkansen trains, both of which are part of the Tōhoku Shinkansen line. The Hayabusa train is the faster option, reaching speeds of up to 320 km/h (199 mph), and can complete the journey in approximately 1 hour and 50 minutes. This service makes fewer stops, including major stations such as Sendai. On the other hand, the Yamabiko Shinkansen takes about 2 hours and 20 minutes for the same journey, as it stops at additional stations, allowing for more access to regional areas. Both trains offer standard and Green class seating to suit different traveler preferences, with comfortable amenities on board such as spacious seating and refreshments. The Hayabusa is the best option for those prioritizing speed, while the Yamabiko caters to travelers looking to explore more regional stops along the way.
