Smart EX for tourists: how to register, pay and ride the Shinkansen (2026)

By the Japan Travel Costs team · 10 November 2026. Every figure links to its source with the date we last checked it, and figures we cannot verify are left out. About us.

Smart EX is the easiest way for a tourist to pay less for a regular Shinkansen ticket between Tokyo, Kyoto, Osaka, Hiroshima and Fukuoka. Joining is free, and a regular-season Nozomi reserved seat from Tokyo to Kyoto costs ¥13,970 (about US$88), which is ¥200 less than the ¥14,170 you pay at the station. That comes from the official Smart EX service price list (labelled as of 1 April 2025) and NAVITIME's fare table, both checked on 2026-11-10.

The ¥200 is not the main reason we use it, though. The real wins are booking from home in your own time zone, changing trains for free as often as you need, and walking through the gate with a phone or an IC card instead of queueing at a ticket office. Here is how it works for a visitor, step by step, with the costs that catch people out.

What Smart EX covers, and what it does not

Smart EX is the online booking service of JR Central, JR West and JR Kyushu. It sells tickets for the Tokaido, Sanyo and Kyushu Shinkansen only: the line from Tokyo through Nagoya, Kyoto, Shin-Osaka and Hiroshima to Hakata and on to Kagoshima-Chuo. Per the official points to note, it cannot be used for other lines and cannot be combined with tickets such as the Japan Rail Pass.

That rules out the Tohoku, Hokuriku and Joetsu Shinkansen out of Tokyo. Those are JR East lines, and our Tokyo to Sendai price guide covers the JR East online options instead. It also means the ticket covers the Shinkansen part only. If you ride a local train to reach the Shinkansen station, that fare is extra, as the smartEX service page spells out.

How to register from overseas

The official registration guide has the full screens. In short:

1. Enter your email. Tap Register on smart-ex.jp and enter an address. Smart EX sends a link from the expy.jp domain, so make sure your inbox accepts it.
2. Agree to the terms. Click the link in the email and accept the membership agreement and privacy policy.
3. Add your details and card. Name, date of birth, a password and a credit card. You have to be 18 or older. Your card will run its own 3D Secure check; if your card does not support it, Smart EX says you may not be able to use the service, or you may need to type the security code every time you book.
4. Add an IC card if you have one. This is optional and can be done later.
5. Wait for the membership ID email. Registration is complete when it arrives.

Two details we would act on. Smart EX sends one-time passwords to your email when you reset a password or get a pick-up code, so it recommends registering more than one address. And the guide warns that you may not be able to collect paper tickets from a machine on the day you register, so sign up a few days before you travel, not on the platform.

Paying: the card rules and the fee nobody mentions

Your card is charged in yen the moment you press Purchase. The Smart EX overview recommends a regular physical credit card. Debit and prepaid cards may see a small test charge, and Smart EX warns that a card company may decline them for this service. Virtual and mini cards lose some features, such as refunds after you pick up a paper ticket.

Here is the cost that surprises people. Every time you change a booking, Smart EX charges the new fare first and then refunds the old one, per the change rules. If your card adds a foreign transaction fee, you can pay that fee again on each change. Change a reservation three times and you may see three sets of fees on your statement. We would use a card with no foreign transaction fee, or settle on your train before you book.

Refunds are simple but not free. Cancel yourself before departure and the fee is ¥320 per person for a reserved seat, per the smartEX service page. After the train leaves you can no longer do it yourself; a set "specified amount" for that section is kept and the rest comes back automatically from the next day, per the refund page.

What you actually save

For ordinary Smart EX fares, the saving on the main Nozomi routes from Tokyo is a flat ¥200 each way in regular season. The bigger drop is Hayatoku 21, the advance fare sold through the same account.

Sources: regular fares from NAVITIME (based on fares effective 14 March 2026); Smart EX from the official smartEX service price list (regular season, as of 1 April 2025, the version linked from smart-ex.jp today); Hayatoku 21 from the official Hayatoku 21 list (as of 13 March 2026). Last checked 2026-11-10.

The Smart EX price moves with the calendar: ¥200 cheaper in off-peak season and ¥200 to ¥400 dearer in peak periods, or double that on routes that cross from the Tokaido to the Sanyo line, per the price list. A typical first trip of Tokyo to Kyoto, then Shin-Osaka back to Tokyo, costs ¥28,890 at the regular fare, ¥28,490 on Smart EX and ¥25,410 (about US$161) if you get Hayatoku 21 both ways. Our Hayatoku 21 guide covers its stricter rules: no changes, a booking window that closes 21 days out, and blackout dates.

Booking, changing and boarding

Ordinary Smart EX seats go on sale from 5:30 Japan time, one year before the travel date, and you can book until 4 minutes before departure, per the reception times page. If you book more than a month ahead, the exact train and seat are confirmed by email about a month before. One booking covers 1 to 6 people, and you can add children.

Changes are free and unlimited until departure, as long as you have not collected a paper ticket or gone through the gate, per the change rules. Miss your train on an ordinary Smart EX ticket and the service page lets you take a later Shinkansen the same day in a non-reserved car.

At the station you have three ways in:

• IC card. Register a Suica, ICOCA or one of the other nationwide IC cards and just tap the Shinkansen gate. The fare comes off your credit card, not the card balance, per the IC card page. Take the "Seat Information" slip the gate prints; the crew checks it. Our IC card guide explains which card to get, and note that Smart EX says IC cards sold to foreign visitors are valid for 28 days from purchase.
• QR ticket. Show it at gates with a QR mark. Every passenger needs their own code, so send each companion theirs, per the QR ticket page. You need it to exit too.
• Paper ticket. Collect it from a ticket machine with the pick-up code. At Tokyo Station, use a JR Central machine on the Yaesu side, per the ticket page. Once collected, you can no longer change it online.

Our practical tips

• Register a week before you fly. The email and card checks are where sign-ups stall, and you may not be able to collect tickets on day one.
• Book early, then adjust. Free changes mean there is little risk in locking in a seat once your rough dates are set. Just watch for repeat card fees.
• Book a luggage seat if your case is big. Bags over 160 cm in total dimensions need a seat with an oversized baggage area, as our Shinkansen etiquette guide explains.
• Do not mix it with a JR Pass. If you hold a pass, reserve through the pass instead. Smart EX is for travellers paying fare by fare.
• Check the live price. Our figures are a planning estimate. The Smart EX booking screen is the price that counts.

Putting it in your budget

If you are taking two or three long Shinkansen trips and no pass, we would register for Smart EX before you leave home. It costs nothing to join, and on the routes above the free changes are worth more to us than the discount. For a family of four, the saving multiplies across every seat.

Not sure whether a pass beats single tickets for your route? Put your legs into our JR Pass vs single tickets calculator, then add rooms and food in the trip budget calculator.
