You do need separate memory cards for both console settings. English or Japanese mode won't access save files on cards formatted to the other.

This. And the easiest thing to do is when you're not paying attention or are tired, accidentally saying "yes" to format your US card while playing a JP game and BAM all your US saves are gone/formatted. That is, if you don't read Japanese and even if you do, auto-pilot can make anyone mess up. Be careful with that stuff~

Yes, but it's important to stress again that what I said is about true JPN console mode.

Often Japan games run under English mode will save.
