This train operates on the Nagano and Hokuriku lines and can reach speeds of approximately 130 km/h (81 mph). The travel time is roughly 2 hours and 50 minutes, depending on the specific schedule and number of stops. During the journey, passengers can enjoy comfortable seating options and scenic views of the Japanese countryside.
In contrast, local trains also run between Iiyama and Komatsu, offering a slower yet more frequent service. These trains typically take around 3 hours and may have more stops along the way, making them suitable for those who wish to explore regional stations. While the limited express train is the optimal choice for speed, local trains provide more flexibility for travelers looking to discover smaller towns.
