The route from Toyama to Takasaki is serviced primarily by the Hokuriku Shinkansen, with options for both Ordinary and Green class seating. The fastest service, the Kagayaki Shinkansen, can reach speeds of up to 260 km/h (162 mph), making the journey in approximately 1 hour and 20 minutes, with fewer stops compared to other services. On the other hand, the Asama Shinkansen takes around 1 hour and 50 minutes for the same trip, as it stops at more stations including Nagano and Ueda, which can be advantageous for travelers looking to explore these areas.
Passengers on both services can enjoy comfortable seating and amenities like food and beverage availability, but the Kagayaki is the better option for those who prioritize speed. The Green Class on the Kagayaki offers additional space and enhanced comfort for a more premium travel experience.
