The route from Koriyama to Oyama is primarily serviced by the Tōhoku Shinkansen and the local Commuter trains. The Tōhoku Shinkansen, operated by the Yamabiko and Nasuno services, provides a high-speed option for travelers. The Yamabiko Shinkansen reaches speeds of up to 240 km/h (149 mph) and can cover the distance in about 60 minutes with limited stops, including stops at major stations such as Sendai and Utsunomiya. Alternatively, the Nasuno service, which is slightly slower, offers a more regional travel experience with additional stops, taking approximately 1 hour and 15 minutes for the same journey.
For travelers looking for more economical options, local Commuter trains are available, but they take longer and offer fewer amenities. Onboard both Shinkansen services, passengers can expect comfortable seating, food and beverage services, and spacious interiors. The Yamabiko is best suited for those prioritizing speed, while the Nasuno is ideal for passengers who prefer greater access to stations along the way.
