While it’s not always required, booking your Shinkansen ticket in advance is highly recommended—especially if you’re traveling during Japan’s peak seasons, such as Golden Week (late April to early May), Obon (mid-August), or the New Year holidays.
Reserving a seat in advance guarantees you a spot on the train, allowing for a stress-free boarding experience and the chance to choose your preferred seating location. Most Shinkansen trains have both reserved and non-reserved cars—with the first 1–3 cars typically designated as non-reserved. While non-reserved seats offer flexibility and don’t require a booking, availability is not guaranteed, and you might have to stand if the train is full.
You can book online, at ticket machines, or in-person at any JR station. If you’re traveling internationally, it’s easiest to book your Shinkansen ticket online with
Rail Ninja or
High Speed Trains before your trip.
