Booking the Shinkansen from home is genuinely easy in 2026 — once you're on the right site. For the Tokaido, Sanyo and Kyushu lines that cover most first trips (Tokyo, Kyoto, Osaka, Hiroshima, Hakata), use SmartEX, which reliably accepts foreign credit cards. JR East's eki-net, covering the northern routes, still rejects most overseas cards. Reserve a seat, add a luggage spot if your bag is big, and you're set.
The short answer
Use SmartEX. It's the official site for the Tokaido, Sanyo and Kyushu Shinkansen — the Tokyo–Kyoto–Osaka–Hiroshima–Hakata spine — and it takes overseas Visa, Mastercard, Amex, JCB and Diners cards. Book from one month ahead, pick a reserved seat, and tap or collect your ticket at the gate. Only the northern JR East lines need eki-net, where foreign cards often fail; for those, many travelers just buy at the station.
Which system for which route
It comes down to which JR company runs the line. SmartEX covers everything from Tokyo westward and through Kyushu, and is the foreigner-friendly default. JR East's eki-net handles the Tohoku, Hokuriku, Joetsu and Nagano routes north and west of Tokyo, and it rejects a lot of foreign cards in 2026. JR West and JR Kyushu also run their own sites with regional early-bird fares. The table sorts the common trips.
| Route | Book on | Foreign cards? |
|---|---|---|
| Tokyo–Kyoto–Osaka (Tokaido) | SmartEX | Yes |
| Osaka–Hiroshima–Hakata (Sanyo) | SmartEX | Yes |
| Hakata–Kagoshima (Kyushu) | SmartEX | Yes |
| Tokyo north (Tohoku / Hokuriku) | eki-net | Often rejected |
SmartEX, step by step
Create a free SmartEX account, register an accepted card, and search by date, route and time. Choose reserved or non-reserved, pick your seat from the map, and pay. You'll get a reservation tied to an IC card plus a QR/booking code. At the station, either tap the registered IC card at the Shinkansen gate or collect a paper ticket from a green machine using your code. Do the account setup at home to avoid fiddling on arrival.
Oversized luggage seats: the rule first-timers miss
If your bag's total dimensions (height + width + depth) run 160–250 cm — most large checked suitcases — you must reserve a 'seat with oversized baggage area' on the Tokaido, Sanyo and Kyushu lines. It's free when booked with your seat; turn up without it and you pay ¥1,000 and hand the bag to staff. Since July 2025 some 16-car trains also trial reservation-free luggage corners, but don't count on finding one. Book the seat.
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. For peace of mind with luggage, on busy routes, or around holidays, reserve — non-reserved cars fill and you may stand. Non-reserved is fine for short, off-peak hops. Note the fastest Nozomi and Mizuho services are reserved-only on some fares and aren't covered by the national rail pass.
Early-bird discounts worth catching
SmartEX sells EX早特 (EX Hayatoku) fares booked a few days to three weeks ahead, shaving roughly ¥1,000–4,000 off popular routes for a limited block of seats; JR West and JR Kyushu offer their own online early-birds. They sell out, so book as soon as the one-month window opens for peak dates. If your plans are firm, the discount is free money; if not, weigh it against the change rules below.
At the station: machines, pickup & IC ride-through
Three ways through the gate. Tap the IC card you registered with SmartEX straight at the Shinkansen gate — smoothest. Or collect a paper ticket from a green ticket machine using your reservation, which you'll want if you booked an oversized-luggage seat. Staffed JR offices (midori-no-madoguchi) handle changes and refunds. Give yourself 15 minutes the first time, since the Shinkansen gates are separate from the local ones.

Frequently asked questions
My foreign card keeps getting rejected — what now?
It's almost always an eki-net (JR East) booking. Switch to SmartEX if your route is Tokaido, Sanyo or Kyushu, since it accepts overseas Visa, Mastercard, Amex, JCB and Diners. For genuine JR East routes north, the reliable fallback is buying at a station ticket machine or office on arrival, or booking through a third-party reseller that takes foreign cards.
Can I change or refund a reserved ticket?
Usually yes, before departure, though discounted early-bird fares are more restrictive and may carry a fee or be non-refundable. Standard reserved tickets on SmartEX can typically be changed to another train at no extra charge before the booked departure. Always read the fare's conditions — the cheaper the ticket, the tighter the rules.
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.
Do I still need a paper ticket, or is it on my phone?
Either works. Register an IC card with SmartEX and you tap straight through the Shinkansen gate — no paper at all. If you prefer, or if you reserved an oversized-luggage seat, collect a paper ticket from a green machine using your booking code. Keep whatever you use until you've exited the gates at your destination.
