Suica top-ups by card
Pick your network and the country that issued the card. Every page says plainly where its answer comes from: these are traveller reports, because no operator publishes a definitive list.
Visa — Often declined
Mastercard — Usually accepted
American Express — Usually accepted
JCB — Usually accepted
Discover — Not confirmed
UnionPay — Not confirmed
Where these answers come from
Nobody publishes a definitive list. JR East does not say which foreign cards it will accept, and the card networks do not say which Japanese merchants will decline them, so the pages here summarise what travellers consistently report. That is useful, but it is not a guarantee, and every page says so.
The pattern in one sentence
Foreign-issued Visa cards are declined at the Suica top-up far more often than anything else; Mastercard, American Express and JCB usually go through; Discover and UnionPay are too thinly reported to call. The refusal happens at the network layer, before it reaches your issuer, which is why it never shows on a statement.
The fallback that always works
Cash. Any station ticket machine and any convenience-store register will top up a Suica, including one held inside a phone, with banknotes. Carry 5,000 yen and a refused card stops being a problem.

Frequently asked questions
Is there a card that definitely works?
No card is guaranteed. Mastercard and American Express are reported to work far more consistently than Visa, but the only method with no failure mode is cash at a ticket machine.
Does it matter whether I use Apple Wallet, Google Wallet or the JR East app?
Yes. The same card can be accepted in one and refused in another. If Apple Wallet refuses you and you are on an iPhone XR or later, Welcome Suica Mobile is worth trying because it is built around foreign cards.
Will my bank charge me a foreign transaction fee?
JR East does not add a fee, but your own issuer may treat the top-up as a foreign purchase and apply its usual currency-conversion charge. If your card works, top up in larger amounts to reduce the number of those charges.
Can I add money with a debit card?
Sometimes. Debit cards on the accepted networks do work for some travellers, but they fail more often than credit cards. Do not make one your only plan.
