The journey from Kumagaya to Niigata is primarily serviced by the Joetsu Shinkansen, which is one of the main high-speed rail services in Japan. This train operates at speeds of up to 240 km/h (149 mph), providing a swift connection between these two cities. The direct service typically takes approximately 2 hours and 30 minutes, making it an efficient option for travelers.
Another option is the local regular train service, which takes significantly longer, often exceeding 4 hours due to multiple stops along the route.
