How to ride the Genbi Shinkansen
Sorry, it is not so easy to ride the Genbi Shinkansen as we already mentioned. Therefore, maybe it is better to book your seat in advance.
You should take the Joetsu Shinkansen to Echigo-Yuzawa from Tokyo. If you want to stay in Nigata, the last station and returning station of the Genbi Shinkansen, the round trip is not necessary. But if you want to go back to Tokyo or to visit other cities, the round trip is better.
