The journey from Tokyo to Kumagaya can be comfortably made using the Limited Express and the Shinkansen services. The Limited Express train, particularly the New Shuttle, travels at speeds of up to 130 km/h (81 mph) and provides a direct route to Kumagaya, taking approximately 40 minutes from Tokyo. It offers Ordinary and Green class seating options, catering to different passenger preferences.
On the other hand, the Tohoku Shinkansen, while not the primary service for this short route, can be utilized but is not as direct. It operates at higher speeds, reaching up to 320 km/h (199 mph), yet it takes longer due to fewer stops, making the trip inefficient for this particular route.
The Limited Express is recommended for a balance of speed and practicality, while those wanting to experience the Shinkansen may find a longer journey and higher fares less appealing for such a short distance.
