The Nagano to Joetsu route is primarily served by the Hokuriku Shinkansen, which provides an efficient travel option for passengers. The fastest service, the Asama Shinkansen, can reach speeds of up to 260 km/h (162 mph) and covers the distance in approximately 1 hour and 10 minutes, with a few key stops along the way, including Nagano, Karuizawa, and Joetsu-Myoko. In contrast, the local express services take about 2 hours as they stop more frequently, catering to travelers who prefer to disembark at smaller stations.
Both train types feature comfortable seating options and onboard amenities such as Wi-Fi and refreshments. The Asama is specially designed for speed, making it a preferable choice for those aiming for a quick journey, while the local services offer a more in-depth experience of the region's landscapes. Passengers can choose between Ordinary Class and Green Class seating on the Shinkansen, ensuring a tailored travel experience.
