The route from Kagaonsen to Iiyama is primarily served by the Limited Express trains, specifically the Hokuriku Shinkansen and the local train services. The Limited Express, such as the Asama, operates at speeds up to 260 km/h (162 mph) and offers a comfortable ride, completing the journey in approximately 50 minutes.

On the other hand, the local trains take longer, typically around 1 hour and 15 minutes, as they stop at several smaller stations along the way. Both train types feature various seating options, and the Limited Express offers more spacious seating and greater amenities. Travelers looking for a speedy trip would benefit from selecting the Limited Express Asama, while those wishing to experience local stations might opt for a local service.
