Traveling from Saitama to Nagano, riders can choose between two notable services: the Shinkansen and the limited express train. The Hokuriku Shinkansen is the primary high-speed service operating on this route, reaching speeds of up to 260 km/h (162 mph). This route facilitates direct access from Saitama to Nagano in approximately 90 minutes, making it an efficient option for both tourists and locals. The Shinkansen offers a range of seating options, including Ordinary and Green class, providing flexibility based on comfort preferences.
Alternatively, the Limited Express Azusa runs the route, offering a scenic experience but at slower speeds, typically around 120 km/h (75 mph), with a travel time of approximately 2 hours and 30 minutes. This service makes several stops at charming smaller stations, appealing to those who wish to explore more regional areas. While the Hokuriku Shinkansen is excellent for those pressed for time, the Limited Express Azusa can provide a more leisurely journey through the picturesque countryside.
