Buying a JR pass online is convenient, and it was very convenient to use on this trip. The only drawback is that you can only reserve seats 7 times using the electronic ticket machine.
After purchasing tickets through the platform, I went directly to the station to exchange them and reserve seats. The whole process was quite convenient and without any major problems. I would consider doing it again if needed in the future.
Convenient and easy to use. From the 7th seat reservation onwards, you need to ask staff to manually assign seats, and the waiting time can be quite long. If you want manual seat assignment, it is recommended to allow plenty of time or use unreserved seats directly.
