The Nagaoka to Niigata route is served primarily by the Joetsu Shinkansen, specifically the Tsubame and Nasuno services. The Tsubame Shinkansen is the faster option, reaching speeds of up to 240 km/h (149 mph) and covering the distance in approximately 62 minutes with limited stops at major stations. Meanwhile, the Nasuno service takes a bit longer, around 83 minutes, as it makes additional stops, providing access to more regional destinations. Both trains feature two classes of seating: Ordinary and Gran Class, ensuring passengers can choose their preferred level of comfort. The Tsubame is particularly appealing for travelers prioritizing speed, while the Nasuno provides a more leisurely journey with additional station access.
