But yes, you need to purchase prime in each country. I have all three.
There is a big bug in prime video, after adding Australia I lost access to all my channels, eg, Starz, AMC+, etc, it didn't seem to support different countries. And changing you default country won't fix it.
Perhaps it works for because you used the same email/pwds?
I set up Amz USA and Amz JPN with different emails/street addresses/payments etc. They are quite different accounts.
