🗺️ Which Card Should You Get?
→ Get Suica if…
- Your trip starts in Tokyo or the Kanto region
- You want to use Apple Wallet or Google Pay (Mobile Suica has broader international support)
- You’re a first-time visitor who wants the most widely-recognized IC card in Japan
→ Get ICOCA if…
- Your trip starts in Osaka, Kyoto, or Kobe
- You’re flying into Kansai International Airport
- You don’t want to worry about topping up — ICOCA works fine in Tokyo too
→ Visiting both Tokyo and Osaka?
Get whichever card matches your first destination. Both work in both cities. The only practical difference is where you can buy and refund them — plan accordingly so you don’t end your trip holding a card you can’t refund.
⚠️ The One Rule That Catches Most Travelers Off Guard
Suica can only be refunded at JR East stations.
ICOCA can only be refunded at JR West stations.If you buy a Suica in Tokyo and end your trip in Osaka, you cannot get your remaining balance or ¥500 deposit back there. You’d need to spend down the balance, keep the card, or visit a JR East station.
If you know your trip ends in Osaka, consider getting ICOCA instead — or use Mobile Suica, which can be refunded online regardless of location, and handles the deposit issue entirely.
🔋 Auto Top-Up: Only Works in the Card’s Home Region
Suica’s auto top-up (オートチャージ) only activates at stations in the Tokyo metropolitan area. If you’re used to never thinking about your balance in Tokyo, note that this feature will not work in Osaka — you’ll need to top up manually at a machine or convenience store.
The same applies in reverse: ICOCA auto top-up doesn’t activate in Tokyo. Either way, you can always top up at any convenience store (7-Eleven, FamilyMart, Lawson) or station machine across Japan.
📱 Mobile Versions: Suica vs. ICOCA on Your Phone
The two cards differ significantly here depending on what phone you have.
Both Mobile Suica and Welcome Suica Mobile work with any iPhone via Apple Wallet, regardless of which country the phone was purchased in. Simply add the card through Apple Wallet — no Japanese Apple ID required. This is the most reliable mobile option for international visitors.
Mobile Suica on Android requires a Japan-specific FeliCa chip (also called Osaifu-Keitai). Standard NFC is not sufficient. This chip is only found in Android phones sold in Japan — international versions of Samsung Galaxy, Google Pixel, and most other Android phones do not have it.
If your Android phone was purchased outside Japan, Mobile Suica will not work on it.
If your Android phone was purchased outside Japan, Mobile Suica and Mobile ICOCA will not work — even if your phone has NFC. The required FeliCa chip is only included in Japan-market Android phones. Your best option is a physical Suica or ICOCA card, or the Welcome Suica physical card available at major airports.
Mobile ICOCA has the same Android FeliCa restriction. It also has a narrower iPhone compatibility compared to Mobile Suica — international Apple IDs may face limitations. Check the JR West ICOCA official site for the latest information before relying on it.
🚄 Can You Use Suica or ICOCA on the Shinkansen?
Neither card works on the Shinkansen by simply tapping at the gate. You first need to link the card to one of these official services:
- Smart EX — Covers Tokaido/Sanyo Shinkansen (Tokyo ↔ Osaka and beyond). Works with both Suica and ICOCA. Free to register.
- Shinkansen e-Ticket (Eki-net) — JR East routes only (Tohoku, Hokuriku, Joetsu Shinkansen). Works with Suica and most IC cards.
- Touch de Go! Shinkansen — JR East short-distance routes only, no advance reservation needed. Works with Suica.

❓ Frequently Asked Questions
Yes. Suica works on all trains, subways, and buses in Osaka that accept IC cards. The main limitations are that you cannot buy or refund Suica in Osaka, and auto top-up doesn’t activate there — so remember to keep your balance topped up manually.
Yes. ICOCA works smoothly on JR East, Tokyo Metro, Toei Subway, and most private railways in Tokyo. You just cannot buy or refund it there — those functions are limited to JR West stations in Kansai.
Not quite. Welcome Suica is a special version for foreign visitors — it has no ¥500 deposit and no 10-year expiry rule. The trade-off is that it cannot be refunded. Regular Suica has a ¥500 refundable deposit but can be refunded at JR East stations.
Not by simply tapping. You need to link your IC card to Smart EX (Tokaido/Sanyo Shinkansen), Shinkansen e-Ticket via Eki-net (JR East Shinkansen), or Touch de Go! Shinkansen (short-distance JR East routes without reservation).
ICOCA can only be refunded at JR West stations (Osaka, Kyoto, Kobe and the Kansai region).Even though both cards work nationwide, refunds are strictly limited to the issuing region. If this is a concern, consider Mobile Suica — it can be refunded online from anywhere.
