Booking the Shinkansen from home is genuinely easy in 2026 — once you know which of two dates matters. For the Tokaido, Sanyo and Kyushu lines behind most first trips, use Smart EX: free to join, six card brands, a QR code instead of paper. But the much-quoted "book a year ahead" window is not what most visitors assume it is, and a foreign card is still the commonest thing that goes wrong. If the fare makes you hesitate, we've run the night bus numbers too.
The short answer
Use Smart EX. It is the official site for the Tokaido, Sanyo and Kyushu Shinkansen — the Tokyo–Kyoto–Osaka–Hiroshima–Hakata spine — it costs nothing to join, and it lists Visa, Mastercard, JCB, American Express, Diners Club and Discover. To choose an exact train and seat, book from 10:00 JST one month before you travel. Board with a QR-Ticket, a registered IC card, or a paper ticket.
One year ahead or one month? The window that actually applies to you
Both numbers are real, and they do different jobs. From 5:30 JST exactly one year out, Smart EX takes one-year bookings on selected products only: it holds you a place, but you get no train number, no departure time and no seat number. Those are assigned at 8:00 JST one month before travel and emailed to you. Normal sales — full choice of train and seat map — open at 10:00 JST one month out. Most visitors want that 10:00 slot.
Which system for which route
It comes down to which JR company runs the line. Smart EX covers everything from Tokyo westward and through Kyushu, and is the default for visitors. JR East's eki-net — JR-EAST Train Reservation in English — handles Tohoku, Hokuriku, Joetsu and Nagano. Its membership terms list VIEW CARD, JCB, Visa, Mastercard, American Express and Diners Club: no Discover, unlike Smart EX. Booking there opens at 10:00 JST one month ahead, with no one-year window at all. A few scenic lines sit outside both systems: the Sagano Romantic Train sells its seats through its own channels.
| Route | Book on | Overseas cards |
|---|---|---|
| Tokyo–Kyoto–Osaka (Tokaido) | Smart EX | Yes — 6 brands, 3-D Secure |
| Osaka–Hiroshima–Hakata (Sanyo) | Smart EX | Yes — 6 brands, 3-D Secure |
| Hakata–Kagoshima (Kyushu) | Smart EX | Yes — 6 brands, 3-D Secure |
| Tokyo north (Tohoku / Hokuriku) | eki-net (JR-EAST Train Reservation) | 5 brands + VIEW CARD — no Discover |
When your foreign card gets refused
The single commonest failure. Smart EX requires the card to be enrolled in 3-D Secure, and its own FAQ warns that debit and prepaid cards often break because a change or refund can double-debit, that an issuer may block overseas settlement, and that some cards are declined for security reasons. Eki-net currently posts an error affecting purchases made with passports from some countries, and advises retrying after arrival. Keep a station fallback.
Smart EX, step by step
Create a free Smart EX account: the sign-up asks for your name, date of birth, email, a password and a credit card, and you must be 18 or over. Register a card enrolled in 3-D Secure, then search by date, route and time. Booking runs until four minutes before departure. Reservations are taken around the clock apart from maintenance, but between 23:30 and 5:30 the seat map is unavailable and bookings cap at three people.
Oversized luggage seats: the rule first-timers miss
If your bag's height, width and depth total more than 160 cm and up to 250 cm, reserve a seat with an oversized baggage area on the Tokaido, Sanyo, Kyushu and Nishi-Kyushu Shinkansen. It costs no more than an ordinary reserved seat; turn up without one and you pay ¥1,000. Over 250 cm cannot board at all. Since 1 July 2025 the deck corners are free shelves for bags up to 160 cm — no reservation needed, and the old corner ticket no longer exists.
Reserved vs non-reserved
Reserved (shitei-seki) guarantees a specific seat for a small premium; non-reserved (jiyu-seki) is cheaper and lets you board any unreserved car. Reserve if you have luggage, travel a busy route, or go near a holiday — non-reserved cars fill and you may stand. Nozomi and Mizuho are excluded from the nationwide Japan Rail Pass unless you buy the NOZOMI MIZUHO add-on in Japan: ¥4,960 from Tokyo or Shinagawa to Kyoto or Shin-Osaka, ¥6,500 to Hiroshima.
When Nozomi runs all-reserved: the dates left in 2026–27
On these dates every Nozomi between Tokyo and Hakata runs with all seats reserved — no non-reserved cars, and a non-reserved ticket buys standing room only. Still to come in FY2026: 18–23 September, 10–12 October, 21–23 November, 25 December–5 January, then 9–11 January and 20–22 March 2027. The three-day weekends were added this year and are the easy ones to miss. Travelling then? Book a seat. A same-day round trip built around a fixed entry slot — a Ghibli Park day trip from Tokyo, say — is the case where you reserve both legs, not just the outbound.
Early-bird discounts worth catching
Smart EX sells EX Hayatoku fares — Hayatoku 1, 3, 7, 21 and Family Hayatoku 7 — on selected sections only. EX Hayatoku 21 puts Tokyo–Hiroshima at ¥15,390 and Tokyo–Hakata at ¥17,920, roughly ¥4,000–5,700 under the standard reserved fare, booked from 21 days out to 23:30 the night before. Blocks are small and Hayatoku is excluded from one-year booking, so buy when the one-month window opens.
At the station: machines, pickup & IC ride-through
Three ways through the gate. Hold the QR-Ticket over a gate marked QR — smoothest, no paper. Or tap the IC card you registered with Smart EX. Or collect a paper ticket from a green machine using your pickup code. JR Central will stop printing the EX seat-information slip around February 2027; seat details move to the app. Staffed JR offices handle changes. Allow 15 minutes: Shinkansen gates are separate. No IC card yet? A Suica in Apple Wallet takes about two minutes to set up.
Frequently asked questions
My foreign card keeps getting rejected — what now?
Check three things. Smart EX lists Visa, Mastercard, JCB, American Express, Diners Club and Discover, but the card must be enrolled in 3-D Secure, and an issuer that blocks overseas settlement will still refuse. Smart EX's own FAQ warns off debit and prepaid cards, because a change or refund can debit you twice or hit an insufficient balance, and says some cards are declined for security reasons regardless. Try a second credit card first. If it still won't go through, buy at a station ticket machine or JR office on arrival — the fare is the same.
Can I really book a year in advance?
Yes, but not the way it sounds. From 5:30 JST one year before your travel date, Smart EX accepts one-year bookings on selected products with a limited seat allocation. What you get is a place held, not an itinerary: the train number, departure time and seat number are only assigned at 8:00 JST one month before you travel, and emailed to you. Cancellation charges apply even before that confirmation. If you want to pick a specific departure and seat from the map, wait for normal sales at 10:00 JST one month out. EX Hayatoku discount fares are excluded from the one-year window entirely.
Can I change or refund a reserved ticket?
Usually yes, before departure. A Smart EX reservation can be changed online right up to your train's scheduled departure, as long as you haven't picked up the paper ticket or already passed the gate with a QR-Ticket or IC card. At a station machine or ticket booth, only the first change is free. Hayatoku fares are tighter: change to a train three or more days ahead and you may keep the same fare, but inside two days you have to switch to a standard Smart EX fare and pay the difference.
Do I still need a paper ticket, or is it on my phone?
Paper is optional on Smart EX. Hold the QR-Ticket over a gate marked QR, or register an IC card with Smart EX and tap through — IC registration is optional, not required. If you prefer, or if you reserved an oversized-luggage seat, collect a paper ticket from a green machine using your pickup code. On JR East, the Shinkansen e-ticket also lets you tap through on a Suica, PASMO or Welcome Suica rather than collecting paper. Keep whatever you use until you've exited the gates at your destination.
Can I ride Nozomi with a Japan Rail Pass?
Not on the pass alone. Nozomi and Mizuho are excluded from the nationwide Japan Rail Pass, but JR Central sells an add-on — the NOZOMI MIZUHO ticket — that lets pass holders board. It costs ¥4,960 from Tokyo or Shinagawa to Kyoto or Shin-Osaka and ¥6,500 to Hiroshima, one ticket per ride, bought in Japan at a reserved-seat machine or a JR ticket office. Hikari and Sakura stay free with the pass. Note the pass itself gets dearer on 1 October 2026: ¥50,000 to ¥53,000 for 7 days, ¥80,000 to ¥84,000 for 14, ¥100,000 to ¥105,000 for 21.
Which side for Mt Fuji views?
On the Tokaido Shinkansen between Tokyo and Kyoto/Osaka, sit on the right-hand side heading west (seats D/E), the left heading east. Fuji appears roughly 40–45 minutes out of Tokyo, near Shin-Fuji, weather permitting. Reserve a window seat on that side if the view matters — it's clearest in the cooler, drier months.
