Not an AIBU but posting here for traffic. We travel to Japan on 30 July and have bought Green J Passes to travel around the country. However, for some of our routes we have gone on to book seats and there are no seats on the trains available. We have accommodation booked and driving is not an option. Can someone with knowledge of trains in Japan offer any advice as to who we would contact/how we might be able to resolve this please. We are really panicking. We are a family of five and even the seats we have managed to book aren’t together.
