Eshop code from Amazon Japan is quite cheap compared to buying locally.
I think the process for this would be moving my account over to Japan, which would also move his, redeeming the eshop code on his account , then switching region back to our local one.
Have I understood that correctly?
FYI:
In order to prevent fraudulent use, the Nintendo eShop and My Nintendo Store for Japan will stop accepting credit cards issued overseas and PayPal accounts opened overseas from Tuesday, March 25, 2025.
For customers who have previously used overseas-issued credit cards or PayPal accounts opened overseas, we ask that you please use other payment methods, such as credit cards issued in Japan, from now on.
Given the definition of fraud likely lies within Nintendo’s user agreements I’d tread lightly.
Edit: this was meant for op.
Thanks, though that’s not relevant here since I’ll be buying the code from Amazon Japan.
If you are getting game code, instead of gift cards, then this should be fine. It would still be better to have a separate JP account for logistics though, or in case Nintendo changes something in the future.
For gift cards, oji has explained the issue below. You get card for $10 and the game is of $9.99 so you are left with $0.01 and then can’t change your region.
Really the bit people seem to be missing the mark on, is whether or not my changing the region on my account will also pull my children across with me and in turn let me redeem the code on my sons account.
From research, I think it will but just really looking for confirmation.
No idea about that, but same rules apply, so if you both have 0 balance, try changing and the account and see. Worse case scenario you will have to change region for two accounts instead of one.
Then I have another warning for you. As long as an account has a positive balance, you cannot change its region. This is especially difficult with gift cards. So, as advised in another comment, it is better to have a separate account for this purpose.
Thanks again, but that’s still not quite the scenario I’m describing. This isn’t a code for a balance, its a code for a game. So there will be no issues on it being positive balance or not. Also while it isn’t possible to do it on your own while having a balance, that are plenty of reports online of Nintendo doing it via support.
I would recommend setting up a secondary JP account, buy games there, and then you can just play them on your main account.
I’ve never tried this, but I bet they’ve already thought of it and found a way to prevent it.
