The route from Takasaki to Nagaoka is served primarily by the Joetsu Shinkansen, offering both Ordinary and Green class seating for different travel preferences. The fastest option, the Toki Shinkansen, can reach speeds of up to 240 km/h (149 mph) and covers the journey in approximately 1 hour and 50 minutes, with limited stops at major stations like Echigo-Yuzawa. In contrast, the Tanigawa Shinkansen takes a bit longer, around 2 hours and 10 minutes, as it frequently stops at more regional hubs, providing access to additional destinations along the way.
Both services offer comfortable seating and various amenities onboard, including food and beverage options. The Toki Shinkansen is perfect for those prioritizing speed, while the Tanigawa allows for more exploration along the route. For travelers seeking an upscale experience, selecting Green Class seating provides extra comfort with added space.
