For the journey from Kurobe-Unazukionsen to Takasaki, travelers can opt for the limited express train known as the 'Hakutaka'. This service operates on the Hokuriku Shinkansen line and typically reaches speeds of around 260 km/h (162 mph). The travel time for the limited express is approximately 1 hour and 50 minutes, with several stops along the route, including Toyama and Nagano, which allows passengers to experience some scenic views of the Japanese countryside.
An alternative option is the local train service, which takes longer, around 2 hours and 30 minutes, making multiple stops in smaller towns. While the Hakutaka offers a faster and more direct route, the local service provides an opportunity to explore areas not covered by limited express services. The Hakutaka's spacious seating and onboard amenities, such as refreshments and restrooms, contribute to a comfortable travel experience.
