Which Shinkansen lines can I book on the SmartEX app?

SmartEX covers the Tokaido Shinkansen (Tokyo to Shin-Osaka), Sanyo Shinkansen (Shin-Osaka to Hakata), and Kyushu Shinkansen (Hakata to Kagoshima-Chuo). It does NOT cover northern JR East bullet trains (Tohoku, Joetsu, Hokuriku), which use the JR-EAST Train Reservation system.

Why is my foreign credit card declining on SmartEX registration?

SmartEX enforces strict 3D-Secure 2.0 fraud verification. Mastercard, JCB, and American Express have the highest success rates. If your Visa card declines, try adding your card through the Apple Pay payment option inside the SmartEX app or call your issuing bank to authorize Japanese transit merchant charges.

How does ticketless IC card boarding work at the Shinkansen gates?

After purchasing a ticket in the app, enter your 17-digit Suica/ICOCA number into your SmartEX profile. When you tap your phone at the Shinkansen turnstile, the gate issues a small printed paper Seat Information Slip (Goannai-sho) showing your car and seat number, and the gate opens.

Can I book tickets for multiple people on one SmartEX account?

Yes! You can purchase up to 6 tickets in a single booking. To board ticketless, enter each companion's separate IC card number. Alternatively, collect QR codes in the app or pick up physical paper tickets at any station ticket machine using a pickup code.
