Traveling from Tokyo to Sanjo is primarily served by the Joetsu Shinkansen, specifically the Max Toki and Toki services. The Max Toki train can reach speeds of up to 240 km/h (149 mp/h) and makes the journey from Tokyo to Sanjo in approximately 2 hours and 30 minutes, providing a quick and efficient experience for passengers. On the other hand, the Toki service also operates on the same line but typically takes a bit longer, averaging around 2 hours and 45 minutes due to extra stops at stations like Ueno and Niigata. Both trains offer two classes of seating, Ordinary and Green class, catering to different preferences in terms of comfort and space. The onboard amenities include spacious seats and the availability of refreshments. Travelers looking for the fastest route will benefit from the Max Toki service, while the Toki allows access to additional regional stops for those looking to explore more along the route.
