It was so amazing, I was amazed there. Information was written everywhere, but it was a bit confusing because there were so many people. If you want to ask, the staff can really help. Ask the staff at the ticket counter, if they can't speak English, there's a template to explain the train lines. I didn't regret booking the JR Wide Pass. It was really suitable and could save a bit. However, for those who don't want to bother going up and down escalators looking for train routes, this is not suitable. You have to have a high adventurous spirit.
