You can charge up the iphone suica balance using cash in the machines... a bit weird but that's what I did.
Getting back home first thing I did was get a mastercard to complement my visa, as it seems EU mastercards still works to charge Suica.
It would be interesting to read about why this happened, it feels like there are interesting payment processing details to learn from it :)
Edit: this article explains it: https://atadistance.net/2023/03/15/troubleshooting-apple-pay... My Visa is actually listed as one of those which still work ("Some VISA debit cards work for adding money to Suica (DKB, Hyundai Zero, Revolut works depending on the country of the account, no other issuers confirmed).")
Not in Japan anymore otherwise I would have tried again.
This article, linked to from a sibling comment here, seems to indicate it shouldn't work for you :) https://atadistance.net/2023/07/15/foreign-visa-cards-blocke...
edit: ha. you read the same articles better than I did.
Is it known whether this foreign-VISA situation is supposed to resolve and get fixed eventually? The article didn't mention whether the current situation is on purpose or an error. I fear that if this is on purpose it might actually get worse and other foreign cards eventually stop working as well.
>Not in Japan anymore otherwise I would have tried again.
I'm neither. Does this change anything? I could charge from home directly in ¥. But the card is from DKB so expected to work.
FWIW I've been using Suica on a Japanese Garmin smart watch and refilling it with Google Pay on an international card without too many problems (and before that with Apple Pay with the same card on iPhone/Apple Watch), although there are probably some gotchas (Apple Pay at POS seems to be pretty hit and miss for in Tokyo and I've never figured out why).
But earlier this year I checked in with some 240 JPY left and found out that I couldn't charge it during the trip... Luckily it was enough for the 2 stations in the Osaka Metro to save me an awkward moment.
