Traveling from Joetsu to Saitama is primarily serviced by the Joetsu Shinkansen, which connects these two regions efficiently. The fastest variant, the Toki Shinkansen, operates at speeds of up to 240 km/h (149 mph) and covers the distance in approximately 1 hour and 50 minutes, making only a few strategic stops at major stations. Meanwhile, the Max Toki, a dual-level train with additional capacity, runs on the same line but may take slightly longer due to more frequent stops, typically lasting around 2 hours and 5 minutes.
Both services offer reserved and non-reserved seating options, with amenities such as power outlets, restrooms, and vending machines available onboard to enhance the travel experience. The Toki is recommended for those prioritizing speed, while the Max Toki provides a unique travel experience with its two levels.
